[edit] Unsourced Facts
Figures shown for radius and density are purely speculative. All we really know from the data is mass and period, unless a reliable source for these figures can be found this data should be removed. Rich.lewis 21:01, 7 May 2007 (UTC)
- I calculated the radius and density of the planet when the star's radius, semi-major axis, and planet mass are known. See talk:Gliese 581 c#Radius for my equation. BlueEarth 01:18, 10 May 2007 (UTC)
On which note, the surface gravity is greater than 2g, if you use the figures currently supplied (M>7.7M_E, R=1.96R_E). Given those figures come with health warnings, I'm not adding that calculated gravity figure to the article. But it may be useful in case the figure gets tied down later.
