Hot blue star

Its story

μ Columbae is a runaway star: a hot young B-type sun ejected some two or three million years ago from the region of the Orion Nebula, likely by the violent breakup of a multiple system. Today she crosses the sky at over a hundred kilometres per second relative to the interstellar medium, leaving her birthplace far behind, some 1,330 light-years from Earth.
