| − | There are four known planets in orbit around Gliese 581, with two inside the star’s [[habitable zone]]. The first, [[Gliese 581c|Gliese 581 c]], is the most widely reported. However '''Gliese 581 d''', discovered later, is a much better candidate for a [[terrestrial]], possibly life supporting world under current terrestrial [[climate]] models. | + | There are four known planets in orbit around Gliese 581, with two inside the star’s [[habitable zone]].
