Simulated gravity-satellites in orbit

[QUOTE="haruspex, post: 4587159, member: 334404"] It says similar to the sun, so assume it has that same mass. The speed with which the ring is 'orbiting' its sun is what you are trying to calculate. But it isn't really orbiting it all, since its mass centre is at the sun. It is merely rotating around its sun. I am a bit worried that it quotes the mass of the ring. Seems like they expect you to take into account its gravitational pull. Not sure how to get that when the point of interest is not on the axis of the ring. As I recall, you can't do that by taking the ring to be a line of zero width - the integral does not converge. [/QUOTE]
