Hi George, welcome to IIS
You've undoubtedly read that News.com report....take no notice of it, even after all the botched corrections they've made. Even if Betelgeuse were to explode now (which it probably won't), you won't see the results of the explosion for about another 625-650 years, which is around the distance the star is from us (625-650 light years). Conversely, if we saw the explosion now, that means it would've actually gone off sometime between 1361-1386.
If there were planets in orbit about the star when it went (goes) supernova, they won't be there now. The explosion would've destroyed them.
