The rotation curve of a galaxy; that is, the orbital velocity as a function of distance from the centre of the galaxy.

In astrophysics, the rotation curve of a galaxy is a graph that plots the orbital velocity of the stars or gas in the galaxy on the x-axis against the distance from the center of the galaxy on the y-axis.
