Only one that we know of. Explanation: The only planet that can support life that we know of is Earth. The set of circumstances for a planet to be able to support life, things like temperature range, atmosphere, available water, and the existence of a magnetosphere are not all that unique to Earth. There are planets in our own solar system that have some of the requirements, but only Earth has all of them. The distances between Earth and even the nearest star besides our own, are so far that although we can determine if those stars have planets and if those planets are in the right temperature range we cannot determine the availability of water on those planets nor can we tell if there is a suitable atmosphere or if there is a magnetosphere. So even though we have found a few planets that might be able to support life we don't know for certain if they could. Drake's equation is an equation that took certain variables and assigned numbers to them to determine the likelihood that humans would find other intelligent life in the universe.
