The Large Magellanic Cloud is a small galaxy that orbits the Milky Way. It is currently orbiting the Milky Way at a distance of roughly 160000 light-years from the galactic center at a velocity of about 300 km/s.
Use these values in the orbital velocity law to get an estimate of the Milky Way's mass within 160000 light-years from the center. (The value you obtain is a fairly rough estimate because the orbit of the Large Magellanic Cloud is not circular.) Express value using one significant figure

Astronomers have observed a small, massive object at the center of our Milky Way Galaxy. A ring of material orbits this massive object; the ring has a diameter of about 12 light-years. If this massive object at the center has a mass of 2.75 x 1037 kg, what is the material orbital speed? Give your answer in km/h.

It is said that at the center of every galaxy is a supermassive black hole (the picture below shows a picture towards the center of the Milky Way from the Keck Observatory). By observing the orbits of nearby stars, you can get a crude estimate of the mass of this black hole by assuming the stars have a circular orbit. Consider the star SO-2, which has an orbital period of 16.3 years. Its average distance from the black hole is...

3. The Milky Way's Dark Matter Halo The Milky Way's rotation curve is approximately a constant, v(r) ~220 km/s, for 5 20 kpc, This constant circular velocity cannot be explained by the observed distribution of luminous mass Instead, we propose that the Milky Way is embedded in a roughly spherical dark matter halo. (a) Calculate M(r), the enclosed mass of the spherical dark matter halo as a function of r in the range 5< T < 20 kpc, assuming the...

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...
