I thought it was found through orbit perturbation analysis -- does that give any indication of size? <br />My recollection is that Earth is unusually dense for a planet, since a lot of the lighter silicas were blasted off in the collision that formed the moon.Mr. Cosmonoreply@blogger.comtag:blogger.com,1999:blog-3953654.post-51293341317983250552010-10-08T07:22:08.000-04:002010-10-08T07:22:08.000-04:00I like footnotes!I like footnotes!Robinnoreply@blogger.comtag:blogger.com,1999:blog-3953654.post-3767881307840648582010-10-07T23:42:06.000-04:002010-10-07T23:42:06.000-04:00I'm holding out for an earth-like planet that ...I'm holding out for an earth-like planet that will provide me with a net subjective weight loss.Philnoreply@blogger.comtag:blogger.com,1999:blog-3953654.post-92016370633577620162010-10-07T20:31:26.000-04:002010-10-07T20:31:26.000-04:00I never thought that would happen.I never thought that would happen.spaceboy 2.0noreply@blogger.comtag:blogger.com,1999:blog-3953654.post-37579652562778911102010-10-07T19:59:08.000-04:002010-10-07T19:59:08.000-04:00It would also mean that you could mow your lawn an...<i>It would also mean that you could mow your lawn any time of the day. </i><br /><br />Sentient lawns don't like to be mowed.DonBoynoreply@blogger.comtag:blogger.com,1999:blog-3953654.post-72245105839610751502010-10-07T19:33:05.000-04:002010-10-07T19:33:05.000-04:00I think in planetary terms, unendurable would &quo...I think in planetary terms, unendurable would "unable to move".

Surface gravity is the mass in multiples of Earth (a minimum of 3.1 here) divided by multiples of Earth's radius (a minimum of 1.3), meaning the minimum estimated gravity would be 2.3 gs. Heavy (I, at 175 lbs, would be 402 there) but no unendurable. Of course, it all depends on further observation and whether it's a rocky or more watery world (the rockier, the higher the density, the higher the gravity).<br /><br />Note that I may have missed a factor here; I've also seen numbers floating around with sub-2 gs.Joseph J.
