Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8 ✕ 1011 solar masses. A star orbiting near the galaxy's periphery is 5.6 ✕ 104 lightyears from its center.
What should the orbital period (in y) of that star be?
If its period is 5.9 ✕ 107 y instead, what is the mass
(in solar masses) of the galaxy? Such calculations are used to
imply the existence of "dark matter" in the universe and have
indicated, for example, the existence of very massive black holes
at the centers of some galaxies.

Andromeda Galaxy, M31, is considered a sister galaxy to Milky Way galaxy. One similarirty is their masses (a) Astronomers have used orbiting satellite galaxies to calculate the mass. At a distance of 190 kpc from the center of M31, the circular velocity of these objects is 150 km/s. Using the measurements and tools that astronomers use, calculate the total mass of M31 in units of the mass of the Sun, M. Watch your units in your calculations! Here are few...
