Hi(adsbygoogle = window.adsbygoogle || []).push({});

I am making a solar system emulation. I need some fairly precise velocities for the planets as a start velocity of the planets and since i calculate the gravity i need it perpendicular in a known distance from the sun.

First of all.. is it correct that if i calculate gravity i would only need the 'start'-velocity(perpendicular) of the planet to be able to simulate a correct path around the sun?

i have searched the web and i don't know where to find them any help?

thanks in advance
