Are there any stars in space that could explode and harm planet Earth?
Scientists say we have to be within 50 light-years of a supernova for it to affect Earth. Iif a supernova exploded within 30 light-years, would severely deplete the base of the ocean food chain.
There are possibly 2000 stars within that range, and 133 of them are visible to the naked eye. But astronomers say with certainty that none of them are massive enough to explode and harm Earth. There has been no supernova within 50 light-years in the known history of humankind.
The closest star that could turn into a Supernova is IK Pegasi B which is 150 light-years away.
Nobody knows how often supernovas erupt in our Milky Way galaxy.
