Comet Machholz, formally designated C/2004 Q2, is a comet discovered by Donald Machholz on August 27, 2004.

It reached naked eye brightness in January 2005. Unusual for such a relatively bright comet, its perihelion was farther from the Sun than the Earth's orbit.

[edit] Return

While this comet will almost certainly return, its extremely large orbit will not bring it back to the inner solar system until approximately the year 111,348.
