Question about velocity...
« on: May 14, 2011, 07:37:18 PM »
I'm trying to simulate a real star, but the only information on velocity I can find are radial velocity, but the game uses the X,Y,Z quadrants. I'm trying to figure out how to use the radial velocity of a given star to accurately input it into the game. Thanks.

The radial velocity can tell you if there is a planet... It's also telling you how it's moving relative us on a dimension through that star and Earth. It's not really possible.

Radial velocity would be the velocity of the star along the axis of the Earth to the star right? If thats what you mean i don't see what you would use that for in US? Unless you are planning on placing the star at its known distance from our star or something?

That would mean it could only go toward or away from us though...

Yup that's what I said in my other post.

Could you link to the site(s)?

Radial velocity is only if you want to accurately make a planetary system around a star.

What is the data you have? Can you give us an example?
