The supernova must be at most 3000 light years away from Earth to have any effect on us. If it is, the ultraviolet and gamma radiation will scorch everything on Earth, and kill all the phytoplankton in the ocean. If the plankton dies, all fish die. If fish die, all fish-eating land animals die, and so on until all animal life on Earth is dead. Plants may survive.
If the supernova is 100 light years away, it will obliterate the planet itself.
we all die
A supernova occurs at the end of a massive star's life cycle.
A supernova can't occur on any planet. A supernova occurs when a very large star, at least 8 times more massive than the sun dies.
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
Iron cannot release energy by fusion. When a star has used up all the lighter elements and has just iron left, it has no more nuclear "fuel". That causes the star to contract then explode very violently as a supernova.

Supernova
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.

No. An asteroid is a piece of rock and/or metal in in outer space. A supernova is an explosion that occurs when a large star dies or when gas accumulates around a white dwarf.
No. Some supernova remnants contain black holes.
