Does Betelgeuse hold the sun?
No, Betelgeuse is too far away to have any effect on the sun.
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.
How far away is Betelgeuse?
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
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.
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.
Do earth have stars?
No, The earth does not have stars. Stars are like the sun. They are so far away that they do not look bright to us. Look at car headlights. When a car is far away, its headlights seem dim. They get brighter as the car gets closer.
How far is Betelgeuse from the sun?
Betelgeuse is about 640 light-years from the sun.
How can betelgeuse look sso bright if it is far away and has a cool surface?
Several things to consider:-- Because of its ENORMOUS size. We believe that Betelgeuse is about as largeas the orbits of the Asteroid Belt. So if Betelgeuse sat exactly where the sun sits,then Mercury, Venus, the Earth, and Mars would all be inside of it.-- Because it's so close to us. Betelgeuse is roughly 800 light-years from us. That'san enormous distance, but actually pretty close as stars go.-- Because it's so hot. The surface temperature of Betelgeuse is estimated at 3,600 K,which is roughly 3,325° Celsius and 5,960° Fahrenheit. That's pretty cool for a star,but you still wouldn't want to touch it.
How long does it take Betelgeuse to revolve around the sun?
Betelgeuse doesn't revolve around the sun. It is a star, even larger than the sun, and much too far away for the sun to have much effect on it.
What does Saturn look like from far away?
From Earth, it looks a lot like a bright star. From further away, it would appear as a dimmer star, or would not be visible at all.
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 .
