Rigel is an intrinsic variable star with apparent magnitude ranging from 0.05 to 0.18. Two stars, components B and C, can be resolved by very large telescopes. The brighter of the two is a spectroscopic binary, the components designated Ba and Bb..
Similarly one may ask, what kind of star is Rigel?
blue supergiant star
Additionally, what stage is Rigel? Which part of the life cycle is the star in currently: Rigel is on the main sequence stage of its life. Temperature: Rigel is estimated to have surface temperatures of around 12,000C (22,000F), more than twice as hot as the Sun.
Similarly one may ask, is Rigel a double star?
It's the first magnitude star β Orionis, better known by its proper name Rigel. Many backyard astronomers are unaware that Rigel is a double star. Its companion (Rigel B) lies 9 arc-seconds away – a gap that should be easily breached by the smallest of telescopes.
Does Rigel have planets?
Rigel incorporates a total of fourteen planets, more than half of them are inhabitable. This large number of class M worlds is attributed to the Hakiel radiation belt that encompasses Rigel A-I, filtering out most of the deadly UV radiation.

Are red or blue stars hotter?
So, the SUN at 5800 Kelvin degrees emits in the visible portion of the EM spectrum and looks greenish yellow. Humans at 300 Kelvin degrees emit in the infrared. Then a blue star is HOTTER than a RED star. The temperature of a blue star is 40000 Kelvin degrees, the temperature of a red star is 3500 Kelvin.Is Rigel hotter than the sun?
It's temperature (36,000 F) is much hotter than the Sun's (10,000 F) and its brightness is about 47,000 times that of the Sun. Rigel, because of its high temperature, is white and is only a bit dimmer than the reddish, cold star Betelgeuse. Rigel is probably one of the brightest stars in our Galaxy.What is the brightest star in the night sky?

In 1871, Sherburne Wesley Burnham suspected Rigel B to be double, and in 1878, he resolved it into two components. This visual companion is designated as component C (Rigel C), with a measured separation from component B that varies from less than 0.1″ to around 0.3″.Why is the Pistol Star Blue?
Pistol star is among the largest known stars. Many of the large stars (eg Betelgeuse) are simply in a temporary red giant phase. For a star (or any radiating body) to appear blue, it has to have a surface temperature of about 10,000K or higher. This can happen with hypergiants and for short times during certain bursts.What does Rigel mean?
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. A companion double star, also bluish white, is of the sixth magnitude. The name Rigel derives from an Arabic term meaning “the left leg of the giant,” referring to the figure of Orion.Why is Rigel white?
