Orbits
« on: May 01, 2011, 09:05:10 AM »
Hey, just got this on steam and it is great!
My only issue so far is when trying to create my own solar system... I'll start with a star then add some planets.  But when I try to add moons around these planets, the lines that show their trajectories act as if the moon is orbiting the sun, but the moon is orbiting the planet fine and its description field shows that it is in fact orbiting the planet, is this a bug or am I missing something?

Thanks.

Have you checked the trails by centering the planet? In this example, I've centered the moon of a planet, with a smaller moon orbiting it, which would be like the planet in your simulation.

If you place the planet further away from the star, and place the moon closer to the planet, its orbit should be more visible (assuming this isn't a bug in the program).

Ah I see :D Thanks!

Is there any option to see each bodies orbit relative to its parent at the same time?

I don't think so, but that'd be a great feature.

Thanks for the responses guys...

This is another orbit question so figured I would just post it in the same thread:
How come in the galaxy scenarios the sun orbits opposite of all the stars/dust that is visible?

That looks strange. Until it's fixed in the official simulation, you can click the Sun, click the box with the velocity on its menu, and from the small list of options, click "reverse velocity".

Projected lines from moons are not relative to the planet they're orbiting they're relative to absolute space. You point out a problem that I have to yet to address. Can you add this to the idea list?
