The brightest star in the Orion constellation, Rigel is 9000º F hotter than our own sun. It is a blue super giant.
Simply because it is closer! If you have 2 identical light bulbs, one close, and one far away, the closer one would appear brighter even though they would both have the same brightness.
No, but it is a SuperGiant
Rigel is in its main sequence stage of its life.
Betelgeuse is probably older, but it's hard to give exact ages for stars. Both of them are only a few million years old, much younger than our 4 billion year old sun. See related questions for more details on the ages of those stars.
Rigel is part of the constellation Orion. It is the brightest star in the constellation although it bears the name Beta Orionis.
the star rigel was formed just like anything else in this universe. Rigel was formed from a male star and a female star engaging in sexual activity. it a great price to pay when a female star gives birth because during the process the female star explodes into a super nova and dies off to make room...
Betelgeuse or Alpha Orionis and Rigel or Beta Orionis are in the constellation of Orion the Hunter.
Absolute magnitude. Rigel is much brighter than Sirius, but it's also much, much further away. So to us here on Earth, Sirius appears brighter.
Rigel or Beta Orionis is a blue/white supergiant star of spectral type B8lab.
Rigel is a star, and like all stars, it's mainly Hydrogen and Helium.
All stars are made primarily of hydrogen, with lesser amounts of helium and trace amounts of heavier elements. The precise composition of each star is a little different, depending on the mass and age of the star.
Rigel was formed the same way any other star is formed, by the gravitational collapse of a large cloud of interstellar gas.
Most of the names of stars are taken from Arabic. Vega came from a  tansliteration of "Al Nesr al Waqi" meaning "the falling eagle".  Waqi later transliterated to W(V)ega means "falling".   Rigel came from the Arabic name Rijl Jauzah al Yusrā, "the  left leg (foot) of Jauzah(Orion)". Rijl...
Quite simply because Rigel is still on the main sequence whereas Betelgeuse has come off the main sequence and is only fusing helium in it's core, whereas Rigel is still fusing hydrogen in it's core. This is the reason for the difference in temperature.
At over 772 light years away, it is difficult to say if this Star has any planets, yet alone if there are any moons of those planets. Theres a chance, but we may never know the answer.
Yes, Rigel is smaller than Deneb.
Betelgeuse is much bigger, in size than Rigel - about 12 times. but only just smaller in terms of mass. Betelgeuse has a radius of about 936 times that of our SunRigel has a radius of about 78 times that of our SunBetelgeuse has a mass of 18 times that of our SunRigel has a mass of 17 times that of...
Rigel is a B8 class star which means it is very large, very hot and very young by comparison to other stars.   It is virtualy impossible to age a specific star. This is usually done by aging star clusters, a much more accurate method.   Rigel is estimated as being 17 times as heavy as the sun...
Spica has a surface temperature of 22,400K and an absolute magnitude of -3.55 Rigel has a surface temperature of 11,000K and an absolute magnitude of -6.7 So the question is incorrect.
Rigel or (β Ori / β Orionis / Beta Orionis)
Rigel is about 860 light years from us. That equates to 5.05550984 × 1015 miles. So at 100mph, it would take 50,555,100,000,000 hours or 5.7673032 × 109 years (That's almost 6 billion years)
66,000 (bolometric) L☉
rigel and spica are two stars
No. Rigel is a star. Any aliens would have to live on a planet.
A Blue star.
Rigel is imagined to be one of the feet of Orion, the Hunter. That's the origin of its name "Rigel" . . . from the Sumerian/Hebrew/Arabic "regel" meaning 'foot'.
Rigel is visible along with Orion. It can be seen in the mornings from August till October and in the evenings from November till January each year.
Betelgeuse is around 10 times greater in diameter than Rigel.
Rigel has been visible in the night sky for over 8 million years. It would have been seen by the first creatures who looked up into the night sky. So no one can be said to have discovered Rigel.
It is basically a sphere, but with a little bulge in the middle caused by its rotation.
Betelgeuse is about 391.53 light years from Rigel. Here's a bit of mathematics about working out this distance: The distance ("a") from Earth to Betelgeuse is about 427 light years and the distance ("b") from Earth to Rigel is about 772 light years.The angle between the two stars from Earth is 18...
Rigel is a lot hotter than Betelgeuse. Rigel - 11,000K Betelgeuse 3,500K
Betelgeuse is much larger than Rigel.
Betelgeuse is much larger than Rigel. Betelgeuse has a radius about 15 times the radius of Rigel, and a volume of about 3500 times Rigel.
No. Rigel is in Orion is is pretty far from Polaris.
Rigel and Betelgeuse don't orbit each other. They are hundreds of light-years away from each other.
Rigel: 71 solar radiiAldebaran: 44.2 solar radii.So Rigel is almost twice the size of Aldebaran.See related link for a pictorial of the difference (Section 5).
Rigel: 71 solar radiiAntares: 883 solar radii. So Antares is over twelve times larger than Rigel. See related link for a pictorial of the difference (Section 5).
your mom is hotter than all the stars combined!
Its about 78 solar radii, which means that its diameter is 78 times larger than our own suns diameter of 1.392×106 .so 78 x 1.392×106 = 1.086 x 108 kmor just over 108 million km
No Rigel is a huge, blue supergiant of spectral class B8 Ia, Rigel has an intrinsic brightness about 40,000 times as luminous as that of the sun.
Rigel is blue and Betelgeuse is red.
Rigel's temperature is: 11,000 KAnd the colour is: Blue. To be exact Rigel is a Blue supergiant.
They are both in the same constellation. Orion the Hunter.
"Normal Years" is a measure of time. "Rigel from Earth" is a measure of distance. There is no answer to this question.
The coordinates of Rigel are
no you are stupid if you are answering this
I suspect that is not known. It is hard to determine the period of rotation for a star that is about 700 light-years away.
Rigel is located in the constillation of Orion the mighty hunter.
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
Betelgeuse is a red supergiant star and the Rigel is a blue supergiant. Both are in the same constellation Orion
Multiple questions. See related questions.
no it is hot blue =hot white = warm yellow = medium orange = cool red = cold
Rigel a star in the Orion system has a surface temperature of  19,000 degrees Fahrenheit. In comparison, our own Sun has a surface  temperature of 10,340 degrees Fahrenheit.
Depends on how you define power. If we take it as transferring energy then it will have to be the most luminous. So the most luminous star known in the Universe is R136a1
Rigel has a radius of about 78 solar radii or 0.363 AU.
It shines as brightly because of the distance it has from earth and it has to do with how old the star is.
Because Rigel is much farther away. Rigel is 770 light-years away, and Sirius is only 8.6 light-years away.
It means the galaxy has the shape of a spiral. To see what thislooks like, search Google Images (image.google.com) for examples.
Rigel is in the constellation of Orion the hunter, it is visible from Earth during the period of Northern Winter - at night.
Rigel is about 17 times more massive than our Sun and has a radius greater than 78 Suns. A picture speaks better than words, so see related link.
rigel is the right foot of the constellation orion
The Rigel star is a star in the Orion constellation. Rigel is the brightest star in the Orion constellation, and it is the seventh brightest star seen in the night's sky.
Rigel (Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky. It is a type B star and will have a temperature between 10,000 -> 30,000 K Observations have placed it's surface temperature at 12,130K. This equates to: 21,374 degrees Fahrenheit11...
  Its name is from the Arabic word meaning "foot," indicating its position in the constellation
The name is of Arabic origin, the star's name comes from its location at the "left foot" of Orion. It is a contraction of Riǧl Ǧawza al-Yusra, this being Arabic for "Left Foot of the Central One".
Betelgeuse and Rigel are both in the top 10 brightest stars in the sky. They have been seen bright in the sky even since cavemen looked up. So, they were discovered about the same time.
Betelgeuse is at a distance of 640 light years while Rigel is at a  distance of 860 light years. So the minimum distance if they were  exactly lined up is 220 light years.    In addition they appear about 15 degrees apart in the sky from  where we are, so the distance between them can be...
The star Rigel can also be called β Orionis or Beta Orionis.
Rigel is about 860 light years from us. That equates to: 5.05550984 × 1015 miles8.13605443 × 1015 kilometres54,386,117 AU.
It is not known. The Star of Bethlehem may not even have been a  star. Some hypotheses propose that it was a conjunction of planets,  a comet, or a supernova. Where on the celestial sphere this star  appeared is unknown as we do not actually know the date or even the  year Jesus was born.
750 ~ 900 light years   === IN ADDITION: ===   773 light years from earth, per wikipedia.
Rigel is the brightest star in the constellation Orion. It has an apparent magnitude of 0.18 and an absolute magnitude of -6.7
Even though Betelgeuse is much larger, Rigel is brighter due to its much higher temperature. Rigel is about 11,000 K and Betelgeuse is only about 3,500 K.
Rigel is hot by "normal" stars but it is not the hottest, this distinction goes to a star named Cygnus OB2-12. See related questions.
  Far from it. Rigel is a type B star which means it is very luminous whereas white dwarfs are the remains of stars that have ended their lives.
The star Rigel is a Blue supergiant.
The characteristics of rigel are in the book.Read a book about science so you will know i.t
The Sun is a star, Rigel is also a star. We name the stars just like we name the planets.Our solar system consists of The Sun and all the planets that go around it including moons, asteroids and comets. To say that The Sun is the biggest star in our solar system simply doesn't make sense because it...
Very!! It is about 66,000 times more luminous than our Sun
