Betelgeuse is 640 light-years away from the Earth.
1 light-year is the distance traveled by light in 1 year.
speed of light = 3 x 108 meters per second
So, 1 ly = 3 x 108 x 365 x 24 x 60 x 60 = 9.46 x 1015 meters
640 light-years = 640 x 9.46 x 1015 = 6.05 x 1018 meters
1 meter = 0.621 x 10-3 miles
640 light-years = 6.05 x 1018 x 0.621 x 10-3 = 3.76 x 1015 miles
That is 3,760,000,000,000,000 miles.

When Betelgeuse explodes how will the Earth be affected?
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.
How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
How far is the earth to Urans?
70 miles
Why is Jupiter in the night sky brighter than betelgeuse?
Jupiter is brighter than Betelgeuse in the night sky because it is much closer to the Earth in comparison to Betelgeuse(Betelgeuse is more than 500 lightyears away form the Earth). This way, Jupiter appears larger than Betelgeuse, and celestial objects that appear larger also appear brighter than objects that appear small.
How far is make make from the sun in miles?
The sun is about 93,000,000 miles from earth.
Why does a star such as Betelgeuse which is located far from earth have much greater absolute magnitude than apparent magnitude?
well my reason is that the betelgeuse must be very large , because they said that the betelgeuse is located far from earth .

Is Betelgeuse going to destroy earth?
No. Some time in the next million years Betelgeuse will explode as a supernova, but it is too far away from us to damage the earth. All we will see is Betelgeuse getting a lot brighter in the night sky.
Beleguise is 520 light year what does this mean?
this means that Betelgeuse, is 3,120,000,000,000,000 Miles from earth perhaps.

Which star is brighter Vega or Betelgeuse?
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)Vega - 0.03.Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.
Does Betelgeuse hold the sun?
No, Betelgeuse is too far away to have any effect on the sun.
How is the sun compared to the star betelgeuse?

How big is Betelgeuse compared to Earth?
Betelgeuse is about 1,180 times larger the Sun. So Betelgeuse is about 128,620 times bigger than Earth. So as a rough approximation about 2,127,774,087,928,000 Earths could fit into Betelgeuse. That's 2 quadrillion.
