What are Some Trans-Neptunian Objects?

Trans-Neptunian objects, often referred to as overseas celestial bodies, refer to celestial bodies that are located in the solar system or whose orbits exceed the range of Neptune. The solar system outside Neptune can distinguish the Kuiper belt and the Oort cloud from the inside out. Pluto and its satellite Charon belong to the outer Neptune celestial body, but considering that Pluto's special orbit is partially within the orbit of Neptune, if Pluto is only discovered now, it may not be considered a planet.

Outer Neptune celestial body

Pluto: Eliminated from the planet in August 2006.

Pluto: The moon of Pluto.

1992 QB1 asteroid ((15760) 1992 QB1): QB1-like object (cubewano).

1996 TL66 asteroid ((15874) 1996 TL66): Scattered disk object (astral object deviating from Earth's orbital plane)

Varuna asteroid ((20000) Varuna): genus QB1.

Ixion (28978) Ixion: The genus plutino.

(90377) Sedna: belongs to the asteroid (planetoid), is an asteroid located between the Kuiper Belt and the Oort Cloud, and may be an object of the Oort Cloud.

Orcus (90482) Orcus: a genus of celestial bodies.

Quaoar ((50000) Quaoar): QB1 celestial body of the genus.

2003 EL61 (2003 EL61): Not yet classified (see [1] and [2]).

Eris (dwarf planet): a celestial discrete celestial body whose orbit is at a 45-degree angle with the ecliptic of other planets in the solar system. Larger than Pluto, the largest known outer Neptune celestial body was announced on July 29, 2005. Currently not among the planets.

2005 FY9 Asteroid (2005 FY9): Not yet classified (see [3]).

The imaginary sun companion, Nemesis, falls under the definition of the outer Neptune celestial body, but it does not actually exist.
