Next perihelion2023-Dec-25[2][5]

During the 2004 perihelion passage the comet brightened to about apparent magnitude 11.[6] The comet was not observed during the 2011 unfavorable apparition since the perihelion passage occurred when the comet was on the far side of the Sun.

On 2049 April 1 the comet will pass about 0.016 AU (2,400,000 km; 1,500,000 mi) from Mars.[1]
