How far can we see into space and what will we see in its vast reaches? Well, a team of astronomers has been able to observe a solar system object, which is 120 astronomical units from the Earth, the farthest one so far.
The second-most-distant observed Solar System object is Eris, at about 96 AU. Pluto is currently at about 34 AU, making 2018 VG18 more than three-and-a-half times more distant than the Solar System’s most-famous dwarf planet.
The discovery images of 2018 VG18 were taken at the Japanese Subaru 8-meter telescope located atop Mauna Kea in Hawaii on November 10, 2018.
Once 2018 VG18 was found, it needed to be re-observed to confirm its very distant nature. 2018 VG18 was seen for the second time in early December at the Magellan telescope at Carnegie’s Las Campanas Observatory in Chile.
