When Betelgeuse explodes how will the Earth be affected?
MarkvanHoppe
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.
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 do you die from a supernova?
If a supernova were to explode nearby, then life on Earth might be impacted by the increased amount of radiation that would strike our planet, especially X-rays and cosmic rays. Fortunately for us, there are no nearby stars which are good candidates to be come supernovas. The closest is the red giant star Betelgeuse, in Orion, at about 800 light years away. When Betelgeuse explodes, it may shine as brightly as the full Moon!
How many earths in Betelgeuse?
The size of Betelgeuse is variable (it pulsates); plus, there are different estimates. But its diameter is approximately 900 times that of our Sun, which in turn is roughly 100 times the diameter of Earth (actually 109, but the data don't justify a very exact calculation), so Betelgeuse has roughly 900 x 100 = 90,000 times the DIAMETER of Earth; the ratio of volumes is that same number, cubed, or (after some rounding) about 700,000,000,000,000 times as much.
Is Betelgeuse a dwarf planet?
Betelgeuse is a supergiant star.

What will happen when Betelgeuse explodes?
If the Sun was replaced by Orion's star Betelgeuse , its size would completely engulf the earth. Also it would extend past the orbit of Jupiter, and most of the planets would be inside the star including Jupiter. Betelgeuse would outshine the Sun like our Sun outshines the Moon. Unfortunately the Earth would have a "Front Row Seat" when the Red SuperGiant blows itself into oblivion. The explosion would be so bright that the star in Orion (constellation) which is 640 Light Years away. Days would still change from day into night, but for a few weeks or so it would appear like there are two Suns in the sky. this is what would happen when Betelgeuse explodes :)
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.
How is the sun compared to the star betelgeuse?
Size-wise, the Sun is to Betelgeuse as the Earth is to the Sun.
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.
How Many astronomical units is the sun from Betelgeuse?
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
How many light years away is betelgeuse?
Betelgeuse is approximately 600 light years from Earth.
Is betelgeuse the farthest star from earth?
No, Betelgeuse is about 640 light-years from earth, but some stars are many billions of light-years away.
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.
