A very interesting star, one of a trio diverging from the constellation Orion. Along with the stars 53 Ari and AE Aur, it likely once formed a stellar system in the constellation Orion, with its fourth component exploding as a supernova 2-3 billion years ago, disrupting the stability of the remaining three, which are gradually moving away from their original position. In our Galaxy, μ Col moves at a speed of about 100 km/s.
