Rigel
Rigel is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18. Although it has the Bayer designation "beta", it is almost always brighter than Alpha Orionis (Betelgeuse).
Rigel B is itself in fact a close binary star with Rigel C. Each of these two stars is of Visual Magnitude 7.6 with a separation of 0.12 arc seconds, corresponding to a separation of 28 AU.
Rigel is the 7th brightest star in the sky. It is called Beta Orionis even though it is brighter than Alpha Orionis (Betelgeuse). This is because Betelgeuse, a variable star, was misclassified. Take a look at the list of the Brightest Stars ...

Rigel is part of the winter circle asterism.
The right shoulder Betelgeuse(alpha orionis), is second brightest and is a variable star. It was named during a period of brightness making it appear more luminous than Rigel.
Rigel of the constellation Orion is a blue supergiant.
Supergiants are pretty much gas with very little solid matter so, despite their enormous size, they tend to be surprisingly low mass.
RIGEL
Rigel (beta Orionis) is the brightest star in the and one of the brightest stars in the sky. It is a blue (very hot) , over 60 million miles in diameter (almost 100 times bigger than the sun).
Rigel has a visual magnitude of mV = 0.18 and distance about 773 light-years

Although Rigel appears brighter than Deneb in the sky (it has a smaller apparent magnitude), they actually have the same real brightness (their absolute magnitudes are the same).

Class A
Class A stars are amongst the more common naked eye stars, and are white or bluish-white.
Beta Orionis (Rigel) has a 10.4 visual magnitude companion at 202º and a wide 9.5" separation. This is a fixed system.
Lambda Orionis (between Betelgeuse and Bellatrix) is another fixed binary, with a 5.5 companion at PA 43º and 4.4" away.
The great star Betelgeuse is one of the two that dominate mighty Orion of northern winter, the other Rigel, the pair respectively also called Alpha and Beta Orionis.
Examples are Cygni (Deneb), Orionis (Rigel), and Ursae Majoris (Alkaid). See navigational stars, table.
In this case the supergiants Rigel and Deneb have the same effective temperature as Sirius but have extremely high luminosities. They have large radii than Sirius hence greater surface areas and higher luminosities.
The leg of the hunter, beta Ori, Rigel (arab.: the foot), is a blue-white giant of 0.08 mag. This makes it the sixth brightest star in the sky and the brightest in the constellation Orion.
Thus, the two brightest stars in the constellation Orion"Betelgeuse and Rigel"are also known as Orionis and Orionis, respectively.

Often distinguished by its belt of three stars, Orion sports a bright blue-white star to the lower right of the belt named Rigel, and a bright ruddy star to the upper left of the belt called Betelgeuse (often pronouced "beetle juice").
For example, the apparent brightness of our Sun is much greater than that of the star Rigel in the constellation Orion because it is so close to us.
[5971] beta Orionis or Rigel ("the foot"), the brightest star in Orion, is the sixth brightest star in the sky. It is a blue supergiant located at Orion's left foot.
The brightest star in Orion is actually Beta Orionis, called Rigel from the Arabic rijl meaning ‘foot' since Ptolemy described it as marking the left foot of Orion. Rigel is a brilliant blue-white supergiant.
The star can be found: west of Zaurak (Gamma Eridani); southwest of Cursa (Beta Eridani) and Rigel (Beta Orionis); northwest of Mu, Alpha (Arneb), and Beta Leporis (Nihal); and southeast of Keid and Beid (Omicron2 and Omicron1 Eridani, respectively).

For example, Rigel (Beta Orionis) is actually slightly brighter than Betelgeuse (Alpha Orionis), and Kappa Orionis is considerably brighter than the position of Kappa in the Greek alphabet would suggest.
Among the brightest stars in our sky is Rigel (β Orionis), in the Orion constellation.
This huge and faint envelope of glowing hydrogen encircles center of Orion and it is a lot larger than marked on finder chart below, almost reaching Rigel. It probably corresponds to intersteller buble or supernova remnant.
ORION
Orion, also known as "The Hunter," is a constellation. The brightest stars in Orion are Rigel. Betelgeuse, and Bellatrix. The Horsehead Nebula and the nebulae M42 and M43 (called the Orion nebula) are also in this constellation.

Eridanus begins next to the bright star Rigel, which represents the foot of Orion. It then meanders its way through the sky. Eridanus originally ended with the star Acamar, which is the last bright star visible to people living in northern latitudes.
