Barnards' Flying Star Planetary System

Barnards' Star Planetary System

I've made an animation of Emerson and Rhoda (click to see), and a near star map (here).

Five (actually, six) planets. Barnards' Star is a 'red' dwarf, but it would actually seem yellow to our eyes, so I used yellow... None of these worlds is 'm class', but the double planet Emerson and Rhoda are super earths with deep oceans under ice. Emerson masses 2.056 Earths and Rhoda masses 1.174 Earths. They’re sort of ice midgets, super Earths with a lot of water and less dense than you might expect, but Emerson has much more water than Rhoda. I think that they are leftovers from a late collision which happened only a few billion years ago when two earlier planets blundered into each other and splashed a lot of mass into orbit around what was left of the previous version of Emerson, so they are in fairly close orbit, a little closer than the Moon to Earth, but of course with three times the mass of Earth they orbit faster, just under a week, about sixty times per local year and each planet’s day has slowed down to that.

Go get Chrome!
