Question

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

science physics

Answer 1

Answer #1

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

Answer 2

Answer #2

Answer 3

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.
