This separation translates into a distance of 12 light days, so it is perhaps not surprising that no orbital motion has been observed, even though the components of the system share the same proper motion trajectory. 35 36 37 Asked in Astronomy, Rigel Is Rigel a blue star? Rigel Statistics. Rigel B is itself a spectroscopic binary system, consisting of two main sequence stars that orbit their center of gravity every 9.8 days. The stars both belong to the spectral class B9V; Rigel B is the more massive of the pair, at 2.5 versus 1.9 solar masses. Rigel A is a massive, luminous star of the spectral type B8 Ia, indicating a bright supergiant appearing blue or blue-white in colour. Mass: 18 x Sun. The name Rigel derives from an Arabic term meaning “the left leg of the giant,” referring to the figure of Orion. Diameter: Approx 65 million miles (105 million km) - 75 x Sun. Luminosity: Approx 117,000 x Sun. Here is some information about each type of known star in our universe. Distance From Earth: Approx 800 light years. The star has a radius almost 79 times that of the Sun and an estimated mass of 21 solar masses. Both members of … – Rigel B: The other component(s) of the system, Rigel B, is actually a binary system in itself, with a separation of more than 2,200 AU between Rigel A and Rigel B. Also Known As: Rigel A, Beta Orionis.
Constellation: Orion. Although main-sequence Red dwarfs are the most common stars in the universe, their are 7 main types of stars in total. With a temperature of 12,100 K, it shines with about 120,000 solar luminosities. Star Type: Class B Supergiant. Rigel is a blue supergiant star with a luminosity more than 100,000 times that of the sun. Rigel or Beta Orionis is a blue/white supergiant star of spectral type B8lab. Due to its measured size and brightness it is expected to end in a supernova one day. Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Temperature: Approx 12,000C (22,000F) Age: Approx 8 … A protostar is … … A companion double star, also bluish white, is of the sixth magnitude. Below, is a simple star color temperature chart that provides examples of some of the most well-known stars in the night sky, and their colors. Protostar: A protostar is what you have before a star forms. A blue-white supergiant in the constellation Orion, Rigel is about 870 light-years from the Sun and is about 47,000 times as luminous. (Its exact luminosity is uncertain, but estimates have been in the range from 61,500 to 363,000 L ☉.)
