Betelgeuse

-6.02

Its diameter is about 6 astronomical units, or 500 million miles, that is about 600 times the Sun's diameter. It is big and unstable, it is only 10 million years old and will probably explode as a supernova in the next million years.

First of all it is important to know that finding exact distance between stars is a very complex and inaccurate process. That said the distance between our sun and Betelgeues star is 640 light years give or take 143 light years. :)

yep its very inaccurate.

In miles 640 lightyears turn out to be 3784292189032320000 miles

Studies since 1990 have produced an angular diameter (apparent size) ranging from 0.043 to 0.056 arcseconds.

the Betelgeuse is colder than the sun

Yes, Betelgeuse is one of the brighter stars in the sky. The red star of Orion's left shoulder is Betelgeuse.

It shines as brightly because of the distance it has from earth and it has to do with how old the star is.

most likely Beteleuse will become a neutron star after the nebula that it will create dies away.

M2

Yes. Betelgeuse is a kind of star called a red supergiant.

1180 solar radius

Betelgeuse has a density of about 1.119 × 10−8 that of our Sun.

Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here.

Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it.

But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!

Betelgeuse is a red supergiant star located in the constellation of Orion. It primarily consists of hydrogen, helium, and other trace elements. Its extreme size and mass make it a unique and intriguing object for astronomers to study.

The surface of Betelgeuse emits light across a broad range of wavelengths, including visible, infrared, and ultraviolet light. The dominant wavelength emitted by Betelgeuse is in the red region of the spectrum, specifically around 700 nanometers.

Betelgeuse is approximately 900 times larger in diameter than the sun, about 1.5 billion kilometers.

No. Check the absolute magnitudes, for example in Wikipedia or in Wolfram Alpha. The LOWER numbers refer to a HIGHER brightness (for visible magnitude) or total power output (for bolometric magnitude).

Betelgeuse is a star, so there is little chance that anyone lives on it.

We will have a pretty sight in the night sky. When it explodes, Betelgeuse is predicted to be almost as bright as a full moon in our night sky for a few weeks. Scientists will also learn a lot about supernovas, from being able to observe one happening relatively close. But, Betelgeuse is too far away to do any damage to Earth.

Maybe because an oil taker named Betelgeuse exploded in 1979 and many were killed, it was called the Whiddy Island disater.

Our own galaxy, the Milky Way. In general, most stars that have a proper name (as opposed to just a catalog number), and definitely all stars you can see with the naked eye (except for an occasional supernova) are part of our own galaxy.

Nothing in real life. But in the movie Betelgeuse will come and visit you and do something.

He will come to your house and when you sleep he will stare at you and scare you all night it's true I tried it and almost pooped my pants.

Betelgeuse is about 600 light years from us. A light year is about 5,878,630,000,000 miles. So to travel there and back would be a journey of about 7,054,356,000,000,000 miles. Nothing can go faster than light and we cannot come anywhere close to going as fast as light. At the speed of light a round trip would be 1200 years. Even if we went at 25,000 miles per hour it would take us over 32 million years to get there and back.
