Found on September 27th by Scott Sheppard (Carnegie Institution for Science), an asteroid now designated as 2025 SC79 turns out to orbit almost entirely inside the orbit of Venus — only the second asteroid ever found so close to the sun, after one called ꞌAylóꞌchaxnim (594913).

“It was very exciting to discover 2025 SC79,” Sheppard tells Sky & Telescope. He first observed it using the Cerro Tololo Dark Energy Camera the night before leaving on a hiking trip. Because the object was moving fast, he knew it must be very close to the Sun, so he’d need to image it again and soon to confirm its orbit before it became lost in the Sun’s glare.
