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]

It has an inclination of 28 degrees.[1][3] As of September 2009, this is the highest inclination of any known Neptune trojan.[3]

With an absolute magnitude of 8.0,[1][3] it has a diameter in the range of 65 to 150 km.[4]

It has been observed 24 times over 4 oppositions.[1]
