2000 YH2
, also written as 2000 YH2, is a trans-Neptunian object. It is a plutino in a 2:3 resonance with Neptune.〔〔
==Pluto-like orbit==
is currently 27.4 AU from the Sun,〔 and came to perihelion in March 2014.〔 This means that this plutino is ''currently'' inside the orbit of the planet Neptune. Like Pluto, this plutino spends part of its orbit closer to the Sun than Neptune even though their orbits are controlled by Neptune. Simulations by the Deep Ecliptic Survey (DES) show that over the next 10 million years may acquire a perihelion distance (qmin) as small as 26.7 AU.〔
It has only been observed 25 times over seven years and has an orbit quality of 4 (fairly average).〔
Assuming a generic trans-Neptunian albedo of 0.09, is about 122 km in diameter.〔 But since the true albedo is unknown and it has an absolute magnitude (H) of 7.8,〔 it could easily be from about 73 to 163 km in diameter.〔
