Our Solar System is located a little more than half way from the galactic center to the edge of the galactic disk.. Let’s look back at the rotational velocity equation:. v = (M. interior. G/r). 0.5. The rotational velocity is constant at big r values.. What must we conclude?. The mass interior to the orbit is still increasing. Even after the radius r has gone beyond the last of the stars. It must be increasing in order to hold v constant.. QuickSign is a revolutionary app made specifically for the Pitt students that come in every year and have to sign people in and out.
