The spiral galaxy known as NGC 2403 lies at a distance of about 11 million light years and is in the constellation Camelopardalis. It is an outlying member of the group of galaxies that also includes M81 in Ursa Major. In 2004, a star in this galaxy believed to be about 15 times the mass of the sun and about 14 million years old became a type II supernova.
