Pushing the boundaries: discovery of the most distant solar system object ever observed - space short science news

For the first time, astronomers have observed an object in our solar system at a distance of more than 100 times the distance from the Earth to the Sun, at 120 astronomical units (AU) to be precise.

For comparison, the distance from Earth to Pluto is “only” 34 AU, and the second-most distant object, Eris, is 96 AU away from us.

Researchers have observed that the newly discovered object, a planet with the provisional name of 2018 VG18, orbits very slowly, making a full orbit in about 1,000 years.
