NGC 3010 is an elliptical galaxy of Hubble type S in the constellation Ursa Major at the northern sky . It is an estimated 206 million light years from the Milky Way .
The object was discovered by John Herschel on March 17, 1828 . The identification of the galaxy is very uncertain. The nearby galaxy NGC 3009 is identified by all sources consulted in the galaxy PGC 28303, with the exception of Professor Seligman, who claims it is the galaxy PGC 28330 (PGC 28335). However, the selection for the galaxy NGC 3010 is complicated, which was also observed by John Herschel that same night. In this region there are three galaxies that are east of NGC 3009 (PGC 28330, 28335 and 28340) and are each classified in NGC 3010 with AC.
Since the galaxy PGC 28830 is the brightest of the three, it may have been observed by Herschel, but according to Professor Seligman it would be NGC 3009, not NGC 3010.
