By Applying Newton's law of gravitation to this speeds, we can deduce the mass of the cluster.
What is a galaxy?
A galaxy is a collection of stellar remnants, stars, interstellar gas, dust, and dark matter that is gravitationally bound to each other. The name comes from the Greek word galaxias, which translates to mean "milky" and refers to the Milky Way galaxy, which houses the Solar System. Galaxies range in size from dwarfs with fewer than one hundred million (108) stars to the largest galaxies known as supergiants with one hundred trillion (1014) stars, each orbiting its galaxy's center of mass. Galaxies are thought to contain an average of 100 million stars.
Therefore, the speeds of individual galaxies can be used to determine the mass of the cluster of galaxies by the method of measuring the speeds and positions of the galaxies in a cluster as they orbit. And then, applying Newton's law of gravitation to this speeds, we can deduce the mass of the cluster.
Determination of mass of cluster using speeds of galaxies orbiting the center:
a) determine a cluster's average speed and redshift measurements
b) To determine each galaxy's individual speed, deduct this average from the galaxy's overall speed.
c) calculate cluster mass using newtons universal law of gravitation and individual speed
