FUN ACTIVITY
The galaxy NGC-55 is located 2 1/3 mpc from the Milky Way. How far is it from the Andromeda galaxy?
In the previous problems, which galaxy is 2 1/15 mpc further from the Milky Way than NGC 552
Answers
Answer:
The Andromeda Galaxy is 3/4 mpc from the Milky Way, while the Sombrero
Galaxy is 12 mpc from the Milky Way. How much further is the Sombrero Galaxy from
the Milky Way? Answer: 12 mpc - 3/4 mpc = 11 1/4 mpc
Problem 2 -The Pinwheel Galaxy is 3 4/5 mpc from the Milky Way. How far is it from the
Sombrero Galaxy? Answer: 12 mpc - 3 4/5 mpc = 8 1/5 mpc
Problem 3 - The Virgo Galaxy Cluster is 19 mpc from the Milky Way. About how far is it
from the Pinwheel Galaxy? Answer: 19 mpc - 3 4/5 mpc = 15 1/5 mpc.
Problem 4 - The galaxy Messier 81 is located 3 1/5 mpc from the Milky Way. How far is
it from the Andromeda Galaxy? Answer: 3 1/5 mpc - 3/4 mpc = 16/5 mpc - 3/4 mpc =
64/20 mpc - 15/20 mpc = 49/20 mpc = 2 9/20 mpc.
Problem 5 - The galaxy Centaurus-A is 4 2/5 mpc from the Milky Way. How far is it
from the Andromeda Galaxy? Answer: 4 2/5 mpc - 3/4 mpc = 88/5 mpc - 15/20 mpc =
73/20 mpc = 3 13/20 mpc
Problem 6 - The galaxy Messier 63 is located about 4 1/5 mpc from the Milky Way. How
far is it from the Pinwheel galaxy? Answer: 4 1/5 mpc - 3 4/5 mpc = 21/5 mpc - 19/5
mpc = 2/5 mpc.
Problem 7 - The galaxy NGC-55 is located 2 1/3 mpc from the Milky Way. How far is it
from the Andromeda galaxy? Answer: 2 1/3 mpc - 3/4 mpc = 7/3 mpc - 3/4 mpc = 28/12
mpc - 9/12 mpc = 19/12 mpc = 1 7/12 mpc.
Problem 8 - In the previous problems, which galaxy is 2 1/15 mpc further from the Milky
Way than NGC-55? Answer; NGC-55 is located 2 1/3 mpc from the Milky Way, so the
mystery galaxy is located 2 1/3 mpc + 2 1/15 mpc = 7/3 mpc + 31/15 mpc = 35/15 mpc +
31/15 mpc = 66/15 mpc = 4 6/15 mpc or 4 2/5 mpc. This is the distance to the
Centaurus-A galaxy.
