163P/NEAT is a periodic comet discovered on November 5, 2004 by Near-Earth Asteroid Tracking (NEAT) using the 1.2 meter Samuel Oschin telescope at Palomar Observatory. [1]
Precovery images of the comet were found by Maik Meyer in December 2004. [6] There were two images from 1997, two images from 1991, and three images from 1990. [7]
During the 2005 perihelion passage the comet brightened to an apparent magnitude of about 16. [8]
Around November 17, 2114, the comet will pass about 0.117 AU (17,500,000 km; 10,900,000 mi) from Jupiter. [9]
