- There are five other long-period comets named Machholz: C/1978 R3 (a.k.a. 1978 XIII, 1978l), C/1985 K1 (a.k.a. 1985 VIII, 1985e), C/1988 P1 (a.k.a. 1988 XV, 1988j), C/1992 N1 (a.k.a. 1992 XVII, 1992k) and C/1994 T1 (a.k.a. 1994 XXVII, 1994r).
, formally designated C/2004 Q2
, is a comet
discovered by Donald Machholz
on August 27
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.
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.
