If only 1 in every million stars had a solar system with a planet like earth then how many earthlike planets would that make in the Milky Way galaxy?
if the Milky way galaxy has roughly 100 billion stars in it like
scientist believe. and the odds of this happning are one in one
million. when you do all the math it works out to be 10000 earths
in our solar system. but that's only if there really is one earth
in a million stars. its almost impossible to know for certain
