If a galaxy is 165 Mly away from us, how fast do we expect it to be moving and in what direction?
Answer in km/s
Here ,
distance , D = 165 Mly
Now , speed of galaxy = Ho*D
speed of galaxy = 20 * 165
speed of galaxy = 3300 km/s
speed of galaxy = 3.3 *10^4 km/s away from us
If a galaxy is 570 Mly away from us, how fast do we expect it to be moving and in what direction?
The rate at which two galaxies are moving away from each other can be determined from Hubble's law. This speed can be estimated by multiplying the distance between the galaxies by the Hubble constant of 20 km/s/Mly. The formula isv Hod where Ho is the Hubble constant and d is the distance between the galaxies. A galaxy is 22 Mly away from the Milky Way. How fast is this galaxy moving away from the Milky Way in kilometers per second?...

Galaxy A moves away from galaxy B at 0.700 c0 relative to B. A spaceship leaves a planet in galaxy A traveling at 0.550 c0 relative to galaxy A. If the direction in which the ship travels is the same as the direction in which A is moving away from B, what do observers in B measure for the ship's speed?
D. (a) How fast and in what direction must galaxy A be moving if an absorption line found at 500 nm wavelength for a stationary galaxy is shifted to 450 nm for galaxy A? (b) How fast and in what direction is galaxy B moving if it shows the same line shifted to 650 nm?

If a galaxy is traveling away from us at 2.0 % of the speed of light, roughly how far away is it?
pls help hurry pupp! If a galaxy moves away from us 4 times its original distance, how would its redshift change? It would remain the same It would increase by a factor of 1/2 It would increase by a factor of 2 It would increase by a factor of ΒΌ It would increase by a factor of 4 A star that is 100 light years away from us has a luminosity of 1 L_Sun. What would its luminosity be if...
2000 Ho=68 km/s MPC + Redshift (km/s) 1000 + + Virgo Cluster + 10 20 Distance (Mpc) 0 The universe is expanding according to Edwin Hubble's famous equation v = Hod where v is the velocity of a galaxy at distance d away. Professional astronomers usually talk about Hubble's Constant in the weird units of H, = 70 km/sec/Mpc. This final unit, "Mpo" is the "Megaparsec" and it equals approximately 3 million light years. This is a powerful equation. It...
