(336756) 2010 NV1, provisionally known as 2010 NV1, is a centaur roughly 20–45 km in diameter. It is on a retrograde cometary orbit. It has a barycentric semi-major axis (average distance from the Sun) of ~286 AU.[lower-alpha 1]
2010 NV1 has a well determined orbit and has been assigned a minor planet number.
It came to perihelion in December 2010 at a distance of 9.4 AU from the Sun.[3] As of 2016[update], it is 14 AU from the Sun.[5]
It will not be 50 AU from the Sun until late 2044. After leaving the planetary region of the Solar System, 2010 NV1 will have a barycentric aphelion of 563 AU with an orbital period of 4830 years.
In a 10 million year integration of the orbit, the nominal (best-fit) orbit and both 3-sigma clones remain outside 7.7AU (qmin) from the Sun.[2]

Notes
- ↑ 1.0 1.1 1.2 Given the orbital eccentricity of this object, different epochs can generate quite different heliocentric unperturbed two-body best-fit solutions to the semi-major axis and orbital period. For objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. Using JPL Horizons, the barycentric semi-major axis is approximately 286 AU.[6]
