Description

2005 VX3 orbits the Sun at a distance of 4.1–1,826 

retrograde orbit and its low Tisserand parameter (TJupiter of −0.9430).[3] It is a Jupiter-, Saturn-, Uranus-, and Neptune-crosser. The body's observation arc begins with its first observation by the Mount Lemmon Survey on 1 November 2005.[1]

2005 VX3 has a

2012 DR30 have a larger barycentric semi-major axis. The epoch
of January 2016 was when 2005 VX3 had its largest heliocentric semi-major axis.

The object has a short

dormant comet that has not been seen outgassing. In the past it may have made closer approaches to the Sun that could have removed most near-surface volatiles. The current orbit crosses the ecliptic just inside Jupiter's orbit and has a Jupiter-MOID of 0.8 AU.[3]

In 2017, it had an

opposition
in mid-June. It would require one of the largest telescopes in the world for any more follow-up observations.

Comparison

The orbits of Sedna, 2012 VP113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine. The three sednoids (pink) along with the red-colored extreme trans-Neptunian object (eTNO) orbits are suspected to be aligned against the hypothetical Planet Nine while the blue-colored eTNO orbits are aligned. The highly elongated orbits colored brown include centaurs and damocloids with large aphelion distances over 200 AU.
