WebIf you know how the mass of a galaxy is distributed we can get a good idea of how fast something would be travelling at any point, if allowed to fall. And by the same argument as above, that gives the escape velocity at that point. The escape velocity around the sun is about 1/600 of the speed of light. WebKeeping that in mind, let's see how we find the mass of the Milky Way. Stars in the disk of the galaxy, like our sun, will basically follow a circular orbit ...
