246P/NEAT is a periodic comet discovered on 2004 March 28 by Near-Earth Asteroid Tracking (NEAT) using the 1.2 m (47 in) reflector at Haleakala.[2] It was given the permanent number 246P on 14 January 2011.[3]
Orbit
It is a Quasi-Hilda comet.[4] Due to perturbations by Jupiter, the 2005, 2013 and 2021 perihelion passages will be closer to the Sun.[5] The comet is observable all through its orbit.[5]
