Two-faced planet

First of: Great software! One of the most amazing things I ever dragged through my modem! I'm new to SE and can't believe I never knew of it before.

So, I'd love to show my first amazing find in SE.

This afternoon I zoomed in a binary system with one white main sequence star and one brown dwarf. Exploring the brown dwarf's satellites I found this little gem:


Notice how one side is blue from the white star and one side is red from the faint glow of the brown dwarf.
More amazed was I when I looked below the clouds:
front:

back:

both:


Looking at the data on the planet it seems one side always faces the dwarf as the orbital and rotation periods are identical.


So, the side always facing the dwarf has no ice!

As the atmosphere on both sides is lit up by the stars it gives the barren terrain two very different faces. (with a pink bunny world in the middle.




It kind of reminds me of the old KOTOR games where red and blue were the colors for the light and dark side. (but that is probably my mind geeking out on me...)



What this makes me wonder though.. Does the engine take the intensity of surrounding stars into account when generating a planet's terrain, or is this effect of no ice on the dwarf-side just a 1/1000000 coincidence?

EDIT: here is the entry for your 'places' file. Fly safely and responsibly!

SE takes into account the illumination by sun(s). Pick any red dwarf star and look at its closest planets - they are often tidally locked as this planet, and have two different terrain types (but if the atmosphere is so dense so it can move heat from day side, the climate may be identical on all surfaces).

That is amazing. Way beyond what I ever thought possible where models for mainstream pc's are concerned. Hats off to you sir! biggrin
