Question
As Earth is a planet of the Sun (a star) that supports life, is it true that there is life on the other planets that travel around Proxima Centauri?
No planets have been discovered orbiting Proxima Centauri, the nearest star. This is a low-mass star and therefore might not be expected to have planets with life. Needless to say, if we can't even determine whether there are any planets, we certainly cannot address your question asking whether there is life. David Morrison
