2007 VL305 is a Neptune trojan discovered on November 4, 2007, by the Sloan Digital Sky Survey. It was first imaged in November 2005, and was the sixth such object to be discovered.[3] It has the same orbital period as Neptune and orbits at the L4 Lagrangian point about 60 degrees ahead of Neptune.[3] As of 2016[update], it is 34.1 AU from Neptune.[4]
It has an inclination of 28 degrees. As of September 2009, this was the highest inclination of any known Neptune trojan.[3]
With an absolute magnitude of 7.9,[1][3] it has a diameter in the range of 65 to 150 km.[5]
It has been observed 30 times over 4 oppositions.[1]
