Still room for an Earth-like planet

edit

So I took all the data in this article and crunched the numbers and figured out that the 1.82 Jupiter mass planet receives 236% of the irradiance that Earth does (Venus being about 191%), and the hill sphere radius is only out to roughly 0.71 AU. That means that there still could be a planet at the 100% distance from the star, which in this case is 1.005 AU, where the solar constant is the same as the Earth. 24.79.36.94 (talk) 22:50, 30 January 2015 (UTC)Reply

In case anyone interested takes it that far, perihelion is 0.69324 AU, the hill sphere then is 0.0577 AU, and the total is 0.751 AU. 24.79.36.94 (talk) 22:50, 30 January 2015 (UTC)Reply
