Large Scale Distances

We’re having trouble with our OpenGL Solar System model. Right now the sun isn’t visable at distances of 5300 (it is a sphere of radius 327). We want to make everything to scale, and at this scale one AU(distance from Earth to the Sun) is about 70,000. How can we make it so that it will make the Sun visable (as small as it may be) at long distances?

Didn’t you just ask this question? I know I just answered it

Anyway, I would suggest scaling your solar system model so that one unit is something like .1 AUs, so that distances don’t get rediculously large (though the radius of a planet may get pretty small in AUs).
