42 Camelopardalis
Hot blue starWhat is 42 Camelopardalis
42 Camelopardalis is a fifty-million-year-old blue B4 subgiant, six and a half times the Sun's mass and spinning at more than a hundred kilometres per second at its equator. Its peculiar velocity through space marks it as a candidate runaway: most likely it was flung from its birth cluster by the explosion of a former companion. It now burns alone 924 light-years away, in the dim northern Giraffe.
