Why does Rigel star shine as brightly as Betelgeuse star?
It shines as brightly because of the distance it has from earth and it has to do with how old the star is.
How far is Betelgeuse from Rigel in the constellation of Orion?
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 18.56 degrees. Knowing these three numbers, we can now use the "law of cosines" to calculate the distance (c) between the stars: c = square root of (a2+ b2- 2ab x cosine of the angle). (In fact, we don't really know the distances to these stars as accurately as this answer may seem to suggest.)
What will happened when star rigel travels in the Earth?
The Earth will be long destroyed by our own sun before that happens.
Is the rigel star moving toward or away from the earth?
Away, at around 18 km/s.
Which is brighter Rigel or Betelgeuse?
Rigel is brighter.
How many normal years is Rigel from Earth?
"Normal Years" is a measure of time. "Rigel from Earth" is a measure of distance. There is no answer to this question.
What distance is rigel have?
Rigel is 260 +/-20 parsecs away.
How many miles does Rigel is away from Earth?
Distances between stars are not measured in miles: that is like measuring the distance from the Earth to the Sun in thousandths of an inch! However, since you asked, Rigel is approx 5 quadrillion miles away.

What is the galaxy called the Rigel star is in?
Rigel is in the same galaxy as Earth is, which is the Milky Way.
How many earth's could you fit inside Rigel?
In the star Rigel, 100,000,000 roughly.
If Deneb and Rigel were located at Alpha Centauri's distance from earth how would they appear?
They would both be bright enough to be seen by, and probably too bright to look at
Is rigel the closest star to earth other then the sun?
No, it is not.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
Rigel has a greater absolute magnitude than Sirius but apears dimmer from Earth do to the farther distance the light waves must travel through space (just a little more information : ), but there are probably alot more stars around that distance
When and where does Rigel appear in the sky?
Rigel is in the constellation of Orion the hunter, it is visible from Earth during the period of Northern Winter - at night.
How far was the rigel to the earth?
Approx 260 +/- 20 parsecs.
