2018 VM35 is a trans-Neptunian object. With a perihelion distance greater than 40 AU, it is considered a detached object. At its discovery it is only the 10th object known with a perihelion over 45 AU and semimajor axis over 150 AU.[3] It is currently 55 AU (8.2 billion km) from the Sun and thus moves slowly across the sky. With a short 89 day observation arc, the orbital parameters are poorly constrained.

Orbit and classification

2018 VM35 orbits the Sun at a distance of about 45.3–426.6 AU once every 3625 years with a semi-major axis of 236 AU. Its orbit has an eccentricity of 0.8 and an inclination of 8.5° with respect to the ecliptic.[2] As with any slow moving object beyond the orbit of Neptune, an observation arc of several years is required to constrain the orbital parameters.

It is predicted to reach perihelion (closest approach to the Sun) around 2057 coming to opposition in February 2058, while only reaching magnitude 24.3.
