Which is the nearest star to us that could go supernova? What would that event look like from earth?

Answer 1

The closest star to us which could go super nova is Pegasi.

Don't worry if you think a supernova will affect us; to qualify as a supernova, a star would need to be 75 light years away; Pegasi is 150 light years away, and Spica is 260 light years away.

Our star neighborhood can be compared to New York City's middle of Kansas.

If observable, a supernova will appear as an exceptionally bright star.

Answer 2

The closest star to go supernova is Betelgeuse. In the event that it does, it would be visible as a sudden and intense brightening of the star, possibly even during the day, that would last for several weeks or months.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
