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.)

How far away is Betelgeuse?
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
Is rigel the closest to Polaris the North star?
No. Rigel is in Orion is is pretty far from Polaris.
What are the primary stars in the constellation Orion?
Orion is probably the best constellation of all, given how bright most of its stars are. In the northern hemisphere it is very clearly seen through the winter months. Orion has many stars. There are 7 very clear stars that people see. They are Rigel Betelgeuse Bellatrix Alnilam Alnitak Saiph Mintaka The two brightest magnitude stars in Orion are Betelgeuse and Rigel. Betelgeuse is the bright red-looking star that, from our perspective, would be top left, or Orion's left shoulder if he were facing away from us. It is in fact a type of star known as a red giant. To the top right of Orion is Bellatrix. Across the centre are the three stars often collectively known as Orion's Belt. From left to right they are Alnitak, Alnilam, and Mintaka. On the bottom right is Saiph, the faintest of the 4 outer stars. It is hard to miss Rigel, which is bright blue-white and would be at the lower right, designating the knee. Many people think of stars as being the same colour, but looking at Rigel and Betelgeuse is a great way of seeing how different in colour some stars are. The famous Horsehead Nebula is to the east of Orion's Belt and far too faint to see with most home telescopes. There is also a nebula in Orion's Sword. If you look closely, one of the "stars" in the sword appears fuzzy; it is not a star but the Orion Nebula. Do a net search for Orion, Betelgeuse, Rigel, constellations, "Orion Nebula," "Orion's Belt," or any combination of these. I'm sure you'll find lots of info. Or better yet, buy yourself a backyard guide to the night sky. You may not use it much, but you'll never regret it. You may even become addicted to astronomy. Astronomy is a simple hobby to start. All you have to do is go outside on a clear night and look up. There are always wonders to be seen.
How far is Orion?
Orion [See Link] is a constellation and thus has many stars of different distances from us.The nearest is GJ 3379 at around 17 light years.The brightest is Rigel at around 800 light years.
What are the list of the stars that make up Orion?
There are thousands of stars in Orion. The three in the belt are Alnilam, Alnitak and Mintaka. The brightest star is Rigel and near that is Saiph. These two stars are in the legs of Orion. On the other side of the belt are the reddish star, Betelgeuse and not far away, Bellatrix. These lie in or near Orion's shoulder. His sword is made up of the stars Pi 1-Pi6.

Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.

Orion [See Link] is a constellation and thus has many stars of different distances from us.The nearest is GJ 3379 at around 17 light years.The brightest is Rigel at around 800 light years.
Is Orion located near a planet?
The planets move around the sun so the planet that is pointed most toward Orion's belt will usually be the closest. Orion's belt is actually three stars that are very far away from each other (just in the same direction) so if you want to be especially precise you have to pick just one of them to ask about.

Does Orion contain any galaxies?
The constellation Orion contains at least 4 galaxies.M78 - NGC 2068M43 - De Mairan's NebulaM42 - Orion nebulaIC 434 - Horsehead Nebulaand many other open clusters.Note: These galaxies lie far, far beyond the group of stars delineating the perimeter of the Orion Constellation. By "contain" we just mean we can see these galaxies out the Orion window.
Why cant you see stars being born in the Orion constellation?
Because they're too far away
How big is the Orion constellation in miles?
The thing is, when we look at Orion we are only looking at a projection. We can see the directions of the stars but we can't see how far away they are. Therefore some of the stars in Orion are close, other are very far away, so it's impossible to say they are grouped together in a volume of space.
How far away a star is?
Bellatrix, is the third brightest star in the constellation Orion. It is a blue giant and is around 240 light years from us.
