It was discovered on 4 November 2007, by astronomers Andrew Becker, Andrew Puckett and Jeremy Kubica at the Apache Point Observatory in New Mexico, United States, although images from 2005 have also been recovered.
[2] It measures approximately 160 kilometers in diameter and was the sixth Neptune trojan to be discovered.
These trojans have a semi-major axis and an orbital period very similar to Neptune's (30.10 AU; 164.8 years).
[3] The discoverers estimate that 2007 VL305 has a mean diameter of 160 kilometers based on a magnitude of 22.2.
[5] Based on a generic magnitude-to-diameter conversion, it measures approximately 110 kilometers in diameter using an absolute magnitude of 7.9 with an assumed albedo of 0.10.
