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.[1] It was given the permanent number 246P on 14 January 2011.[5]
Orbit
[edit | edit source]It is a Quasi-Hilda comet.[6] Due to perturbations by Jupiter, the 2005, 2013 and 2021 perihelion passages will be closer to the Sun.[7] The comet is observable all through its orbit.[7]
