"Dynamical mass of the O-type supergiant in ζ Orionis A". Neutral. The system was first resolved as a binary star system in 1819 by German astronomer George K. Kunowsky. Three of the components are B-type main sequence stars with stellar classifications of B1 V, B3 V and B2 V.[3], This entry is from Wikipedia, the leading user-contributed encyclopedia. Rank. However, because most of the radiation emitted is in the ultraviolet, the total luminosity of Zeta Orionis is some 100,000 times of the Sun.[7]. (2004). DSS2 image of η Orionis.

Orion. It is, in fact, the brightest class O star seen from Earth in the night sky. It is estimated to have 14 times the mass of our Sun, and some 1,100 times the visual luminosity, even though much of the radiation is in the ultraviolet. [12], It has also been suggested that component Ab is intrinsically variable with a period of 0.3 days and a very small amplitude.

Aus Scheinbarer Helligkeit und Entfernung errechnet. An equivalent to over seven times the distance of Pluto from our Sun. Amongst the 85 additional doubles I included Eta Orionis but I also added a third star at 115" of magnitude 9.4 - can't remember why!!

It has an apparent magnitude of 4.2, making it normally visible in dark skies, but it is obscured by the much brighter Zeta Orionis Aa.
