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.. .. 1. First spiral nebula found in 1845 by the Earl of . Rosse. .
