With the redshift determined, you can now easily calculate the radial velocity of the galaxy. To do this multiply the z by the speed of light, 299,793 km/s. The answer will be the radial velocity of the galaxy in kilometers per second. For example, if you calculated z to be 0.01417, then the radial velocity would be 4407 km/s. Use the formula below to calculate NGC 1050's radial velocity and record that value in the space below
