Simulation program: Celestia

I have this program, Celestia, and this is the Google of the known universe. It rendwers a beautiful view of all stars, galaxies and other things known at this time in space. with a click of a mouse button, you can travel to Zeta Ret. system, or anywhere else.
Does anyone else use this program?

Yes I have used it to take a tour of our solar system, but I don't know enough about how to use it. I guess I don't know enough about astronomy or I'm not very good at math.

I'll bet a lot of ATS users would love it if they don't know about it already.

I use it quite a lot. For some things it is better than Stellarium, but harder to use.

OMHO there is place for both of them on my PC.

One of the chief reasons to use it is the good visualization of orbits.

when you zoom out a little, and you see the immenseness ov the galaxy, it reminds you of how small and insignificant we are
