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 about apparent magnitude 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]
