659 Nestor is a Jupiter Trojan asteroid orbiting the Sun. Along with the other Jupiter Trojans in the Greek Camp, it orbits along Jupiter's path, about 60 degrees ahead of the planet.

Photometric observations of this asteroid during 1995 were used to build a light curve showing a rotation period of 15.98 ± 0.03 hours with a brightness variation of 0.31 ± 0.01 magnitude.[1]

On 30 June 2006 it occulted TYC 6854-00630. The duration of the disappearance (9.52 seconds) equates to a size of at least 109 km diameter.
