 但現在 60AU 發現一群

a cluster of approximately a dozen icy objects lying beyond 60 astronomical units (AU), nearly as far from Pluto as Pluto is from the sun.

The revelation has led to speculation about the existence of a second Kuiper belt, challenging the conventional boundaries of our solar system.
The finding, though preliminary and awaiting peer review, gains support from measurements taken by New Horizons, which is venturing beyond the known Kuiper belt at 57 AU (an astronomical unit is roughly the distance from Earth to the sun and approximately equal to 150 million kilometres, otherwise 93 million miles).
