It is a multiple star system, composed of a large B-type blue giant and a more massive O-type main-sequence star. The Mintaka system constitutes an eclipsing binary variable star, where the eclipse of one star over the other creates a dip in brightness. Mintaka is the westernmost of the three stars of Orion's Belt, as well as the northernmost. [6]
The major stars of the σ Orionis cluster, described in the text, plus: HD 294268, F6e, probable member HD 294275, A0 HD 294297, G0 HD 294300, G5 T Tauri star HD 294301, A5 . The σ Orionis cluster is part of the Ori OB1b stellar association, commonly referred to as Orion's Belt. The cluster was not recognised until 1996 when a population of ...
HD 34445 is a star in the equatorial constellation of Orion. With an apparent visual magnitude of 7.31, [ 2 ] it is a 7th magnitude star that is too dim to be readily visible to the naked eye. The system is located at a distance of 150.5 light years from the Sun based on parallax measurements, but is drifting closer with a high radial velocity ...
Rigel is generally the seventh-brightest star in the night sky and the brightest star in Orion, though it is occasionally outshone by Betelgeuse, which varies over a larger range. A triple-star system is separated from Rigel by an angle of 9.5 arc seconds. It has an apparent magnitude of 6.7, making it 1/400th as bright as Rigel.
The three stars of θ 2 Orionis within the Orion Nebula. θ 2 Orionis consists of three stars in a line, each about an arc-minute from the next. In addition to the well-known three stars, the Washington Double Star Catalog confusingly lists a component D which is actually θ 1 Orionis C. [16] There is one other star brighter than 10th magnitude ...
HD 34989 is a blue-white star in the main sequence, of apparent magnitude 5.80, [2] in the constellation of Orion. It is 1700 light-years from the Solar System . HD 34989
The photos Orion snapped on its first near pass to the Moon were rather grainy and blown out, ... It launched on November 15th as part of the Artemis 1 mission atop NASA's mighty Space Launch System.
