a) How does this distance compare with the diameter of the Milky Way? If we used the Milky Way's diameter as a measuring stick, how many "Milky Ways" away is it? b) What is the distance to the Andromeda Galaxy in kilometers? You'll need to look up how many kilometers there are in a light year and convert from the distance in light years above. c) If it is moving toward our galaxy at 110 km/s, how long (please give the answer in years, use scientific notation as needed) before the Andromeda Galaxy and the Milky Way merge? Calculate your answer using your distance in part b. You can start by finding the time in seconds and then converting to years. There are 3.15 x 10' seconds in 1 year. Remember time is just distance divided by speed.
