There are huge spaces between stars. The biggest threat to Earth would be the gamma radiation emitted, which could sterilize the Earth from as far as 10 light-years away.
Mass. E=MC2 Supernova explosions happen with the most massive of stars > 20 of our Suns.
Supernova
er\we
Life on earth would cease to exist.
it would increase
we would stop getting the warmth a light
Ok to start the solar system spins around the sun because of the suns massive gravitational pull. #2 the sun will not go super nova because its mass is not the same as 1.4 suns and has no way of gaining mass so it cant go supernova.
Emperor of the Fading Suns happened in 1997.
No. A Red Dwarf is a very low mass star - less than our Sun. Only massive stars > 20 Suns will result in a supernova [See Related]
It takes about 8 minutes for the Sun's light to get to Earth. So if the Sun explodes because of a Supernova or other, we would know 8 minutes later!
In 1968 a group of Phoenix Men bought the Suns.
Not in our Sun, but heavy elements up to and including iron are formed in very massive suns (stars). Elements heavier than iron are formed with suns die in a supernova.
