Is there any supernova candidate in the neighbourhood of the earth, near enough to be able to annihilate us due to the radiation?

Which is the minimum distance a supernova can stay whithout friying us?

anybody knows?

Off the top of my head, I don't think there are any candidates close enough to be of great concern. Correct me if I'm wrong.

In general, any planets of a star going supernova are going to be deep fried...

As for the Earth, Betelgeuse might put on an interesting show but I think we'll be ok...
