NGC 2403 was discovered in 1788 by the German-British astronomer Wilhelm Herschel. It is a spiral galaxy with prominent spiral arms in the constellation of Camelopardalis in the northern sky. In the center of the galaxy are several large, open star clusters with massive, very hot stars embedded in HII regions.

NGC 2403 is a member of the so-called M81 galaxy group and is about 11 million light years away. In 2004, the 2004dj supernova erupted in this galaxy. Already in 2002 SN 2002kg and before SN 1954J was observed in NGC 2403.
