Beta Orionis, also known as Rigel, was a binary star system. [4] Rigel is the most luminous star in our local region of the Milky Way; the nearest more powerful star is Deneb, almost 1,500 light years away in Cygnus. Rigel A was a B class star with a magnitude of -7. Rigel, one of the brightest stars in the sky, intrinsically as well as in appearance. Contrasting with the orange-red Betelgeuse, Rigel appears as blue-white to the naked eye.

Rigel, brightest star in the easy-to-see constellation of Orion the Hunter, shines with a blue-white color. Rigel is a Blue supergiant at 17 solar masses, it shines with approximately 40,000 times the luminosity of the Sun. Rigel is a Binary or Multiple star system. Rigel B was a B class star. Rigel is located at a great distance from the sun (330 parsecs) and has a high luminosity—81,000 times greater than the luminosity of the sun. All three stars together make up … – Rigel A: This is a blue-white supergiant with an absolute magnitude of -7.84. Beta Orionis was located 773 light years from the Sol system, in non-aligned space in the Beta Quadrant. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. The most energetic stars out there are the blue stars. Rigel (Beta Orionis) is a blue supergiant, normally the brightest star in Orion (although variable Betelgeuse can occasionally overtake it), and the seventh brightest in the sky.

A companion double star, also bluish white, is of the sixth magnitude. The history of the star: Rigel. Rigel is the 7th brightest star in the night sky and is the brightest star in Orion based on the Hipparcos 2007 apparent magnitude.

The Universe Today. It is expected that Rigel will eventually end its life in a type II supernova explosion, providing the material for future star formation. Space and astronomy news. RIGEL (Beta Orionis). The star Rigel is made up of 3 separate stars, they call them Rigel A, B, and C. Two of the stars are white and the other is blue right now.

Rigel is the 7th brightest star in the night sky and has an extremely high intrinsic luminosity. Stars can also change in luminosity over time. With over 120,000 solar luminosities, it’s not quite as powerful as Deneb, but it’s still by far one of the most powerful stars within 1000 lightyears of Earth. The Rigel Star has a temperature of _____K and a luminosity of 10,000 and 100,000 The vast majority of stars on the Characteristics of Stars diagram are classified as Rigel is also a multiple star system – composed of at least four stars. Rigel Technology is a Singapore-based company that specializes in developing innovative and eco-friendly bathroom solutions – encompassing design, manufacturing, marketing & supply of green restroom products. Rigel has a radius that is 78.90 times bigger than the Suns. A similarly named Rigel Beta ultimately made its way into canon in Star Trek Into Darkness. Radius – Rigel A: This is a blue-white supergiant with an absolute magnitude of -7.84. The two main components of this binary star system are Rigel A and Rigel B. 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. Rigel is a massive blue supergiant with a luminosity of around 61.500 up to 363.000 that of the Sun. from p.312 of Star Names, Richard Hinckley Allen, 1889.
