Rho Orionis, Latinised from ρ Orionis, is the Bayer designation for an orange-hued binary star system in the equatorial constellation of Orion.It is visible to the naked eye with an apparent visual magnitude of +4.44. [2]
Xi Orionis (ξ Orionis) is a binary star system in the northeastern part of the constellation of Orion, well above the red giant star Betelgeuse in the sky. It lies next to another blue main-sequence star, Nu Orionis, which is somewhat closer at 520 light-years' distance.
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.
Meissa / ˈ m aɪ s ə /, designated Lambda Orionis (λ Orionis, abbreviated Lambda Ori, λ Ori) is a star in the constellation of Orion. It is a multiple star approximately 1,300 ly away with a combined apparent magnitude of 3.33. [12] The main components are an O8 giant star and a B-class main sequence star, separated by about 4
Pi 6 Orionis (π 6 Ori, π 6 Orionis) is a solitary [9] star in the eastern part of the constellation Orion. It is visible to the naked eye with an apparent visual magnitude of 4.469. [2] Based upon an annual parallax shift of 3.45 mas, [1] it is around 950 light-years from the Sun.
This is an A-type main-sequence star with a stellar classification of A3 Va. [3] It is a Lambda Boötis star, [8] which means the spectrum shows lower-than-expected abundances for heavier elements. [9] Pi 1 Orionis is a relatively young star, just 100 million years old, [5] and is spinning fairly rapidly with a projected rotational velocity of ...
V380 Orionis is a multiple star system containing at least three stars. A very faint cool star 9" away is also thought to be gravitationally bound, making it a hierarchical quadruple system. Two infrared sources within NGC 1999 have been listed as companions in some catalogues, [7] but are not thought to be stars. [8]
Eta Orionis or Algjebbah, Latinized from η Orionis, is a multiple star in the constellation Orion. It lies a little to the west of Orion's Belt between Delta Orionis and Rigel, being closer to Delta Orionis than to Rigel. It lies at a distance of around 1,000 light-years from Earth and is part of the Orion OB1 association.
