What is a Comet?
什麼是彗星

Comets are basically dusty snowballs which orbit the sun. They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust. These materials came from the time when the solar system was formed. Comets have an icy center (nucleus) surrounded by a large cloud of gas and dust (called the coma). The coma is created as the ice in the nucleus is warmed by the sun and vaporizes. Comets can develop 2 tails as they travel closer to the sun, a straight gas tail and a curved dust tail. The gas tail is created by the solar wind, whose magnetic fields pull the gas away from the comet's coma. The dust in the coma is not affected by magnetic fields but is vaporized by the sun's heat, and forms a curved tail which follows the comet's orbit.
彗星基本上是繞太陽軌道的髒雪球 , 通長是由水,冰,碳氫化合物 , 氨和甲烷等且混合了塵埃。這些材料來自太陽系形成時的時間。彗星有一個冰冷的中心(核)周圍繞著的氣體和塵埃(彗髮)大雲。彗髮 是因為冰核被溫暖的陽光和蒸發產生 。彗星可以發展2尾巴,當他們的旅行更接近太陽,直氣的尾巴(離子尾) 和一個彎曲的塵埃彗尾。彗星的尾巴是由太陽風的磁場吹走彗星彗髮的氣體。在彗髮中的塵埃是不受磁場的影響但受太陽的熱蒸發,並形成如彎曲的尾巴隨著彗星的軌道




When will Halley's comet return?
何時哈雷彗星會回歸
Halley's comet will next appear in the night sky in the year 2062. It orbits the sun every 75-76 years, so this is the time between appearances. Halley's comet was recorded by Edmund Halley in 1682. It was seen again in 1758, 1835, 1910, and 1986.
哈雷彗星的將出現在夜空中是在2062年。它軌道繞太陽每隔75-76年,所以它出現的時間。埃德蒙_哈雷在1682年記錄到哈雷彗星的記錄。並在1758年,1835年,1910年和1986年再次看到。


Did a comet really crash into Jupiter?  
彗星真的會撞進木星嗎?
Yes, between July 16 and July 22, 1994, several pieces of Comet Shoemaker-Levy 9 collided with Jupiter. It was the first collision of two solar system objects ever observed. The comet had been captured and broken apart by Jupiter's strong gravity. More than 20 fragments of the comet crashed into Jupiter's southern hemisphere at speeds of about 130,000 miles (210,000 km) per hour. The impacts released a lot of energy and created several large, dark scars in Jupiter's atmosphere which lasted for several weeks.
是的,7月16日至1994年7月22日,幾個蘇梅克 - 列維 9號彗星的碎片與木星相撞。這是兩個太陽系天體頭一次碰撞被觀察到。這顆彗星被木星的強大引力抓住,並被撕裂(ps. 潮夕力撕裂 蘇梅克 - 列維 9號彗星 ) 。超過 20彗星的碎片以每小時約 13英里(210,000公里)的速度撞向木星的南半球。撞擊釋放出大量的能量,並產生了幾個大的,黑暗的疤痕在木星的大氣層並且持續幾個星期。

What is the difference between an asteroid and a comet?
小行星和彗星有何差異
The main difference between asteroids and comets is what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago. Asteroids formed much closer to the sun, where it was too warm for ices to remain solid. Comets formed farther from the sun where ices would not melt. Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail.
小行星和彗星之間的主要區別在於它們是由什麼樣的東西組成。小行星是由金屬和岩石物質,而彗星是由冰,塵埃和岩石物質。小行星和彗星都在45億年前的太陽系早期形成的。小行星的形成更接近太陽,它太溫暖所以只留下岩質物體。彗星在遠離太陽且冰不會融化的地方形成。彗星當靠近太陽時因為軌道是結構鬆散的材料,當他們的冰融化和蒸發會形成一條彗星的尾巴。


What is the size of a comet?  
彗星大小有多大
Most comets have a nucleus (the center of a comet) that is less than about 6 miles (10 km) wide. The size of a comet changes depending on how close it is to the sun. As a comet gets closer to the sun, the ices on the surface of its nucleus vaporize and form a cloud called a coma around the nucleus that can expand out to 50,000 miles (80,000 km). A tail also forms on a comet as it approaches the sun. Comet tails can be over 600,000 miles (1 million km) long.
大多數彗星是小於約 6英里(10公里)寬的原子核(彗星的中心)。彗星大小的變化取決於它如何靠近將太陽。當彗星接近太陽時,其內核表面上的冰蒸發,形成雲稱為彗髮圍繞彗核能夠擴大到50,000英里(80,000公里)。當它接近太陽也會形成彗尾。彗尾可以超過 60萬英里(1萬公里)長。


What is a meteor shower?  
什麼是流星雨
As a comet travels close to the sun, it heats up and part of the comet vaporizes. After a comet has orbited the sun many times, a lot of small pieces of the comet are left along the comet's path. A meteor shower happens when Earth passes through the path of a comet. When this happens the bits of comet debris, most no larger than a grain of sand, create streaks of light in the night sky as they burn up in Earth's atmosphere Bits of debris which enter Earth's atmosphere are called meteors. On any night, there are several small meteors which shoot across the sky. However, during a meteor shower, tens to hundreds of meteors can be seen each hour. Many of these meteor showers can be predicted and occur at the same time each year.
彗星旅行接近太陽,太陽加熱彗星使其一部分蒸發。在彗星繞太陽很多次後,很多彗星殘渣離開彗星的軌道。流星雨發生在地球通過彗星的路徑上。當這種情況發生時彗星碎片多數沒有比一粒沙子大,在地球大氣層燃燒會在夜空中產生條紋的光,當這些進入地球大氣層時被稱為流星雨。在任何一個晚上,有幾個小流星劃過天空拍攝。然而在流星雨期間,可以每個小時看到幾十甚至幾百流星雨的,在每年同一時間這些流星雨有許多是可以預測。

拜咕狗大神,答案就來了。
什麼是彗星?

彗星基本上都是圍繞太陽旋轉的塵土飛揚的雪球 。 它們是由冰,水,二氧化碳,氨和甲烷等,混合了灰塵。 這些材料來自太陽系形成時的時間 。 彗星有一個冰冷的中心(核)周圍的氣體和塵埃(昏迷)大雲。 昏迷中被創建為冰核是由溫暖的陽光和蒸發。 彗星可以發展2尾巴,因為他們的旅行更接近太陽,直氣的尾巴和一個彎曲的塵埃彗尾 。 氣體的尾巴是由太陽風的磁場拉距彗星的昏迷氣體。 在昏迷中的灰塵是沒有磁場的影響,但太陽的熱量蒸發,並形成如下彗星的軌道彎曲的尾巴。

What is an asteroid?
什麼是小行星
Asteroids are rocky-metallic objects which range in size from about the size of pebbles to around 600 miles (~1,000 km) across. Although they orbit the sun, they are too small to be considered planets. Asteroids are thought to be leftover material from the formation of our solar system. Most are found in the Asteroid Belt, a doughnut-shaped ring which lies between the orbits of Mars and Jupiter. Astronomers have also identified a group of asteroids whose orbits cross Earth's orbit. Several hundred thousand asteroids are known to exist in our solar system, and many are yet to be discovered. Most of the undiscovered asteroids are the smaller ones (less than 100 km across) which are more difficult to detect. It is estimated that there are over a million of these smaller asteroids.
小行星是岩石的金屬物體的, 尺寸範圍從鵝卵石般大小到越約 600英里(約1000公里)都有。雖然它們圍繞太陽旋轉,它們太小,無法被視為行星。小行星被認為是我們太陽系的形成後留下的材料。大多數是在小行星帶位於火星和木星軌道之間的一個環形圈。天文學家們還發現了小行星的軌道和地球的軌道有交叉。數十萬小行星被稱為存在於我們的太陽系,許多人尚未被發現的。未被發現的小行星大多是較小的(小於 100公里橫跨),這是更難以察覺。據估計,有超過百萬顆這些更小的小行星。



What is the asteroid belt?
什麼是小行星帶
The asteroid belt is a region of space between the orbits of Mars and Jupiter where most of the asteroids in our solar system are found orbiting the sun. The asteroid belt probably contains millions of asteroids. Astronomers think that the asteroid belt is made up of material that was never able to form into a planet, or of the remains of a planet which broke apart a very long time ago. The asteroids in the asteroid belt come in a varity of sizes. Some are very small (less than a mile across), while others are quite large. The largest asteroid is called Ceres. It is about one-quarter the size of our moon
小行星帶是在火星和木星之間的空間 ,其中大部分小行星繞太陽的軌道在。小行星帶中可能包含數以百萬計的小行星。天文學家認為,小行星帶是由沒有能夠形成一個行星的材料組成,或是行星球很長一段時間前解體。在小行星帶的小行星有多種尺寸。有些是非常小(不到1英里),而有些則是相當大的。最大的小行星被稱為穀神星。這是我們的月球大小的大約四分之一


What is the largest asteroid?
小行星最大是那個
The largest asteroid is called Ceres. It is about one-quarter the size of the moon and orbits the sun between Mars and Jupiter in a region called the asteroid belt. Unlike most asteroids, Ceres is spherical in shape. Ceres was discovered by the Italian astronomer Giuseppe Piazzi in 1801 as he searched for a planet which was predicted to exist between Mars and Jupiter. It was the first asteroid ever discovered.
被稱為最大的小行星是穀神星。大約四分之一的月亮的大小其軌道在火星和木星之間的太陽在一個區域稱為小行星帶。不像一般小行星,穀神星是球形的。穀神星被發現在1801年由意大利天文學家Giuseppe Piazz ,他預測火星和木星之間可能存在行星做行星搜索。這是迄今發現的第一個小行星。

Can asteroids have moons?
小行星有衛星嗎 ?
Yes, asteroids can have moons! Some of the larger asteroids in our solar system actually do have moons. In 1993, an tiny moon called Dactyl was discovered orbiting the large asteroid Ida. Dactyl is only about 1 mile wide, while Ida is about 19 miles across. Since then, several other moons have been discovered orbiting asteroids. In 1999 an 8 mile wide moon called Petit-Prince was discovered orbiting the 135 mile wide asteroid Eugenia. In 2000, the 90 mile wide asteroid Pulcova was discovered to have its own moon, about nine miles wide. Over two dozen more have been discovered.
是,小行星有衛星!其實在我們的太陽系的一些較大的小行星有衛星。在1993年,大型小行星艾達( Ida) 發現一個一個小衛星叫 Dactyl 。 Dactyl只有約 1英里寬,而IDA是約 19英里。從那時起,數個繞小行星的軌道衛星被發現。在1999年8英里寬的月亮,稱為Petit-Prince  被發現繞135公里寬的小行星尤金妮亞Eugenia軌道上。在2000年,90英里寬的小行星Pulcova發現有自己的小衛星,大約9英里寬。2l41vu到現在已經發現了超過兩打多的小行星衛星 。

Can you really walk on an asteroid like in some movies?
可以在小行星上行走類似電影上嗎 ?
Since asteroids are generally small, their gravity is very weak. An astronaut standing on an asteroid would weigh very little and would tend to float more than walk.
由於小行星一般都比較小,其重力性是非常薄弱。太空人站在一個小行星上重量會很輕,比較像在是飄浮不像在步行

Can an asteroid really hit Earth?
小行星會撞上地球嗎 ?
It is possible that an asteroid may hit Earth one day, but the chances of this happening are very small. Most asteroids are located in the asteroid belt and stay between the orbits of Mars and Jupiter which is very far from us. However, some are in orbits which can take them closer to Earth. Astronomers are always watching the sky and some of them specialize in tracking these asteroids. If an asteroid was heading for Earth, chances are that we would know about it years ahead of time and would have a lot of time to plan a defense.
一顆小行星有可能某天撞上地球,但這種情況發生的可能性非常小。大多數小行星都位於離我們很遠的火星和木星軌道之間的小行星帶。然而,有些小行星軌道會使小行星更接近地球。天文學家們一直看著天空,其中一些專門跟踪這些小行星。如果這顆小行星會是地球頭號問題,機會就是我們會了解它, 在今後幾年的時間會有很多的時間計劃和防護

Have any spacecraft landed on an asteroid?
有任何太空船登陸過小行星嗎 ?
Yes, on February 12, 2001 flight controllers landed NASA's NEAR spacecraft on an asteroid called Eros. NEAR was the first spacecraft to orbit and touchdown on the surface of an asteroid. NEAR began orbiting Eros a year earlier, on February 14, 2000. The spacecraft collected close up photographs and measured the size and shape of Eros before landing. Eros is the largest of the asteroids whose orbits cross the orbit of the Earth.
是的,2001年2月12日,美國航空航天局nasa控制的近地小行星任務太空船的降落在一個愛神小行星。近地小行星任務太空船是第一個繞小行星。軌道和接觸小行星,  近地小行星任務太空船在一年前2000年2月14日 開始繞愛神小行星軌到, 太空船在降落前收集愛神的特寫照片和測量大小和形狀。在有穿越地球的軌道的小行星軌道中愛神星是最大。

How hot is Mercury?
水星多熱
Since Mercury is the closest planet to the sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury's temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day (This is hot enough to melt lead!).
由於水星是最靠近太陽的行星,緩慢的旋轉,並且不會有大氣抓住熱,它的溫度差別很大。水星的溫度可以在晚上華氏零下279度(攝氏零下173度) 白天到 華氏801度(攝氏427度)之間  ( 熱到足以融化鉛)

Why does Mercury have more craters than the other planets?
水星為什麼比其他行星有更多隕石坑
All of the planets in our solar system have had a lot of craters. This was especially true in the past when there were many more meteoroids traveling in our solar system than there are today. On planets like Venus, Earth and Mars, we do not see as many craters because most of them have been eroded away by wind, rain, volcanic activity and other forces. On the giant gas planets, Jupiter, Saturn, Uranus and Neptune, we do not see any craters because there is no visible solid surface for the meteors to hit. On the Mercury, where there is no atmosphere, there is no weather to erode away the craters, so most of the craters are still visible.
How small is Mercury compared to Earth?
在我們的太陽系的行星都l有很多隕石坑。這是在過去時有更多的隕石在太陽系流浪,在金星,地球和火星等行星上我們沒有看到很多隕石坑,因為他們大多數已被風,雨,火山活動和其他勢力的侵蝕。在巨大的氣體行星,木星,土星,天王星和海王星,我們沒有看到任何隕石坑,是因為沒有可見的固體表面可被隕石擊中。對水星來說,那裡是沒有大氣,有沒有天氣會削弱了隕石坑所以大部分的隕石坑仍清晰可見




水星和地球比有多小
Mercury has a diameter of 3,032 miles (4,879 km) making it a little more than one third the size of Earth. If Earth were the size of a baseball, Mercury would be about the size of a golf ball.
水星直徑是 3032 英里 (4879 公里) , 略多於三分之一的地球大小的。如果地球是一個棒球的大小 水星將一個高爾夫球大小。

How strong is the gravity on Mercury?
水星上重力多強
Since Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.
由於水星的質量比地球少,水星表面的重力小於地球表面引力。水星上的表面重力只有約38%的地球表面引力,因此,如果你的體重100磅地球上,你在水星上只有38磅



How close is Mercury to the sun?
水星離太陽多近
Mercury is the closest planet to the sun. It's orbit around the sun is very elliptical, like a stretched out circle. Mercury's distance from the sun ranges from 28.6 million miles (46 million km) to 43.4 million miles (69.8 million km).
水星是最靠近太陽的行星。它繞太陽運行的軌道是非常像橢圓形的像一個伸出的圓圈。水星離太陽的距離從2860萬英里(4600萬公里)到4340萬英里(6980萬公里)範圍



How fast does Mercury orbit the sun?
水星繞太陽軌道多快
Mercury circles the sun in only 88 days, compared to 365 days for Earth, at at an average speed of 107,088 miles (172,341 kilometers) per hour. This is faster than any other planet in the solar system.
水星繞太陽公轉只有88天,相比地球繞太陽公轉為 365天 , 每小時的平均速度107088英里(172341公里)。比太陽系任何行星都還快。



How long is a day on Mercury?
水星一天多長
A planet's day is the time it takes the planet to rotate or spin once on its axis. Mercury rotates very slowly compared to Earth so a day on Mercury is much shorter than a day on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long.
一個星球的一天是星球軸線的旋轉或自旋。和地球比水星的旋轉非常緩慢,所以水星上的一天比地球上的一天短?Huh?Huh?。水星上的一天是58.646個地球日或1407.5小時,而地球上的一天長23.934小時

===> 這邊有問題 , 字面說 水星上的一天比地球上的一天短 ,
但轉得很慢 應該是 比地球的一天還長吧 ..如以地球時間為單位



How long is a year on Mercury?
水星一年多長
A year on Mercury is about 88 Earth days long. Mercury has the shortest year of any planet in the solar system.
一年約 88地球天,  比起其他行星水星有最短的一年

How far is Mercury from Earth?
水星離地球多遠
Mercury is the first planet from sun and Earth is the third planet from the sun. Mercury is an average distance of 48 million miles (77 million km) from Earth
從太陽數來水星是第一顆行星和地球的是從太陽數來的第三顆行星。從地球到水星的平均距離4千8百萬英里(7千7百萬公里)

Does Mercury have an atmosphere?
水星有大氣層嗎 ?
Mercury has an extremely thin atmosphere which is made up of atoms blasted off its surface by the solar wind, a constant stream of particles coming from the outer layer of the sun. Because Mercury is so hot, these atoms quickly escape into space. Unlike the stable atmospheres of Earth and Venus, Mercury's atmosphere is constantly being replenished
水星極有其稀薄的大氣,它是由原子組成是因為來自太陽的外層粒子的太陽風,其表面由於水星會這麼熱,這些原子迅速逃逸到太空。不像地球和金星有穩定的大氣。水星的大氣中須要不斷地被補充。

What is the weather like on Mercury?
水星上的氣候是如何
Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat)
由於水星幾乎沒有任何大氣,它並沒有像風暴,雲,風或雨的天氣。白天其表面溫度可達到華氏801度(因為它是如此接近太陽),晚上可以下降到華氏零下279度(因為沒有大氣會抓住白天的熱)

What does the sun look like from Mercury?
從水星上看太陽會如何
Since Mercury is the closest planet to the sun, the sun would look much larger from Mercury than it would from any other planet in the solar system. From Mercury the sun would appear to be about 2 1/2 times larger than it appears from Earth.
由於水星是最靠近太陽的行星,太陽看起來會比從任何其他行星在太陽系水星較大。從水星上看太陽會比從從地球上出現大約2.5倍


What is Mercury made of?

Mercury is a rocky planet with a huge iron core which makes up a large part of its interior. The core takes up nearly 3/4 of the planet's diameter. Mercury's iron core is about the size of the moon. Iron makes up about 70% of Mercury's total weight making Mercury the most iron-rich planet in the solar system. On top of this core, lies an outer, rocky shell which is about 350 miles (~550 km) thick.
水星是與一個巨大的鐵核,這使得其內部的很大一部分的岩石行星。核心佔用了行星的直徑近3 / 4的。水星的鐵的核心是差不多是月球的大小。鐵核新約佔水星的總重量約 70%使水星在太陽系中是含鐵最豐富的星球。在這個核心之上,其外層這是約 350英里(約550公里)厚的岩石外殼

How old is Mercury?
水星有多老
Mercury was formed at the same time as the rest of the solar system, from a large spinning disk of gas and dust. Astronomers think that all this happened about 4.6 billion years ago! So Mercury is about 4.6 billion years old
水星和太陽系的其餘部分的同時期形成,從一個大的旋轉的氣體和塵埃形成。天文學家認為,約 46億年前發生的這一切!因此,水星約 46億歲

=> 怪了  billion 是 10億 ..為何 4.6 billion  google 一直翻  4.6億 Huh?



How many spacecraft have been to Mercury?
有多少太空船到過水星
Only one spacecraft has ever visited the planet Mercury. It was called Mariner 10. During 1974 and 1975, Mariner 10 flew by Mercury three times and mapped about half of the planet's surface. Mariner 10 also discovered Mercury's thin atmosphere and detected its magnetic field.
只有一個太空探測器到過水星。它被稱為水手10。在1974年和1975年,水手10號飛越水星三次,並照過水星表面一半左右。水手10號還發現水星的稀薄的大氣層和偵測到它的磁場。

Who discovered Mercury?
誰發現水星
There is no single person who is credited with the discovery of Mercury. Mercury is one of the five planets that can be seen in the night sky without using a telescope or binoculars. The planet Mercury has been known since ancient times and was observed for thousands of years by the people of many different cultures. One of the earliest records of Mercury comes from the Sumerians around 3,000 BC. Since Mercury never travels far from the sun in the sky, it is more difficult to see and was probably discovered later than brighter planets like Venus, Mars, Jupiter and Saturn.
沒有任何單一的人發現水星的記錄。水星是五個行星之一且不使用望遠鏡或雙筒望遠鏡就可以在夜空中看到。自古以來一直被稱為水星,是由許多不同文化的人民千百年來觀察。水星的最早記錄之一是大約公元前3000年的蘇美爾人。由於水星在天空中從未遠離太陽 ,這是比較難見到,可能是因此 發現比其他明亮的行星,如金星,火星,木星和土星還晚。

How did Mercury get its name?
為何會取名為水星 ? 
The Romans knew of seven bright objects in the sky, the sun, the moon and the five brightest planets. They named them after their most important gods. Because Mercury was the fastest planet as it moved around the sun, it was named after the Roman messenger god Mercury. Mercury was also the god of travelers. According to myth, he had a winged hat and sandals, so he could fly.
羅馬人知道七明亮的物體在天空,太陽,月亮和五個最亮的行星。他們命名是取其最重要的神名。因為水星它繞太陽移動是最快的行星,它被命名為水星是羅馬神話中眾神的信使。水星也是旅行之神。根據神話,他有翅膀的帽子和涼鞋所以他能飛。

ps. 中國又稱為辰星 但 水星中文名稱由來 Huh???



How long does it take to get to Mercury from Earth?
從地球到水星要多久
How long it would take to travel to Mercury would depend on where Earth and Mercury were in their orbits at the time a spacecraft started its journey from Earth, and also on the path chosen. For example, Mariner 10 was launched on November 3, 1973 and it arrived at Mercury on March 29, 1974.
太空船從地球到水星要多久和地球和水星的軌道間位置有關,  所選擇的道路上也將取決於此。例如,水手10號,1973年11月3日發射,它在1974年3月29日到達水星。


Is there any water on Mercury?
水星上有水嗎 ?
Recent radar data shows that water ice may exist in the bottoms of craters at Mercury's poles. Although Mercury is the closest planet to the sun, and can be extremely hot over most of its surface, ice may exist at the bottoms of some polar craters because the crater floors are permanently shadowed by the crater rims. Mercury's axis has almost no tilt, so its poles receive very little direct sunlight.
最近的雷達數據顯示水冰可能存在於水星的兩極的隕石坑底部。雖然水星是最靠近太陽的行星,且其表面非常熱,冰可能存在於一些極地隕石坑底部,因為火山口底部是陰影區。水星的軸幾乎沒有傾斜,所以它的兩極收到直射陽光很少。

What color is Mercury?
水星是甚顏色
Planets have the colors that they have because of what they are made of and how their surfaces or atmospheres reflect and absorb sunlight. Mercury has a dark gray, rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust
行星的顏色是因為它們是由其表面或大氣反射和吸收太陽光產生。水星有一個暗灰色,這是一層厚厚的灰塵覆蓋的岩石表面。該表面被認為是由火成岩的矽酸鹽岩石和塵埃
