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.
