Nine are known as extreme trans-Neptunian items, which have orbits that swing out at least 150 AUs from the sun. At these distances, the objects are barely affected by Neptunes gravity, but their unusual orbits suggest an impact from outside the solar system. In this case, the items share Neptunes orbit around the sun.
They consist of dwarf planets such as Pluto and Eris as well as small Kuiper Belt things like Arrokoth, a rocky body checked out by the New Horizons spacecraft in 2019. Nine are understood as extreme trans-Neptunian things, which have orbits that swing out at least 150 AUs from the sun. At these ranges, the items are hardly affected by Neptunes gravity, however their weird orbits recommend an influence from outside the solar system. The newly found things might thus help scientists sharpen in on the possible Planet Nine– or disprove its existence.The researchers also discovered four new Neptune Trojans. In this case, the things share Neptunes orbit around the sun.
