Is there a way to make realistic orbits and rotations with the earth, moon and sun. Also, will there be eclipses?
-
Yes, the plan is to use available data for realistic positions of bodies. At the moment sun position is computed for given time of day and day of year.
Eclipses probably too, when there's some time to implement it for such a rare event, though we don't aim to be an astronomical simulator - there's plenty of those out there.

Hi cameni,
even if not an astronomical simulator, do you think outerra will support/implement something to see other planets like:

Actually, for that you don't need anything special, just to render the other planet. Atmospheric lighting takes care of the rest. See, for example, this topic: http://www.outerra.com/forum/index.php?topic=158.0 (http://www.outerra.com/forum/index.php?topic=158.0)

But how many have Games being made in them?..
none.

Wow. So after the moon is rendered and I look up to the sky Ill see the moon and not some "skybox" thing? Wow. Thats gona be awsome!!!

like Kerbal Space Program :)

Oddly enough, I know a little bit about the math regarding that, so if Cameni or Pig gets something wrong, they're GOING to hear about it if and when they implement it.
j/k ... I wouldn't know math from a cheese cracker.

Would there be a problem with the earth hurdling 67,000 Mph around the sun?
-
It's matter of properly chosen reference frames. Ultimately, everything is converted into camera space for rendering. Positions of planets and moons are going to be computed in a solar coordinate system; to render the moon you'd add the difference of camera and moon positions to coordinates of objects in the local moon-space system .. etc.

Ok I think I understand.
