'''Gliese 581 d''' is an [[extrasolar planet]] orbiting the [[red dwarf]] [[star]] [[Gliese 581]]. Due to its mass it can be categorized as a [[Super-earth]].<br />
<br />
Gliese 581 d is near the outer edge of the habitable zone. <ref>{{cite web |url=http://arxiv.org/PS_cache/arxiv/pdf/0705/0705.3758v1.pdf |title=The Habitability of Super-Earths in Gliese 581 |accessdate=2007-05-29 }}</ref><br />

== Climate and habitability ==<br />
Although Gliese 581 d orbits outside the theoretical [[habitable zone]] of its star, scientists surmise that conditions on the planet may be conducive to supporting life[http://www.space.com/scienceastronomy/070618_mm_gliese_581d.html]. Scientists originally believed that Gliese 581 d would in fact be too cold for liquid water to exist, and therefore could not support life as we understand it. However, due to a theorized [[greenhouse effect]], research now suggests that atmospheric conditions on the planet create temperatures at which water can exist, and therefore the planet may be capable of supporting life. It is important to note that these conditions are based on models of the planet, and have not been directly observed.<br />
