Шаблон:Short description

Шаблон:Use dmy dates Шаблон:Infobox planet Шаблон:Mp, provisionally known as 2001 XH255, is a trans-Neptunian object (TNO) that has a 4:5 resonance with Neptune.[1]

It will come to perihelion in 2041.[2]

Assuming a generic TNO albedo of 0.09, it is about 100 km in diameter.[3]

Resonance

According to the Deep Ecliptic Survey and Minor Planet Center, Шаблон:Mp has a 4:5 resonance with Neptune.[1][4] It comes as close as 32.2 AU from the Sun and has a fairly low orbital eccentricity of 0.07 with an inclination of only 2.86 degrees.[2]

The Neptune 4:5 resonance keeps it more than 7 AU from Neptune over a 14000-year period.[5]

It has been observed 21 times over 5 oppositions and has an orbit quality code of 3.[2]

Potential for Exploration

A NASA study in 2019 that confirmed the viability of using small radioisotope or nuclear fission power systems combined with xenon electric propulsion for deep space exploration, used 2001 XH255 as a representative Kuiper Belt Object as the mission's destination to orbit.[6]
