Hubble Law Distance Calculator: Trying to calculate the Hubble distance of galaxy? Don't worry you can learn the step by step process to calculate the Hubble law distance in a simpler manner. We are here to help you in finding the answer to Hubble distance questions using Hubble's law. Want to know more about the concept, then go through the below sections.

Step by Step Process to Calculate Hubble Distance

The following are the steps to calulate the distance between earth and the galaxy with the help of Hubble's law.

  • Get the speed of the galaxy.
  • Divide the speed value by the Hubble constant.
  • The result is the distance to the galaxy.

What is Hubble's Law?

Astronomers first saw that galaxies are moving away from us. One astronomer named Edwin Hubble and George Lemaitre says that the speed they are moving is directly proportional to the distance between them.

Hubble's law states that the galaxies in the universe move away from us faster and farther than they are from us. And it was proportional to the Hubble constant. Its formula is

v = Ho D

D = v/Ho

Where,

v is the speed of the galaxy

Ho is the Hubble constant and value is 70.4 km/s per million-light-years

D is the distance to the galaxy

After finding the shift in observed light into redshift in the spectrum, one can calculate the distance of the galaxy from us using Hubble's equation. The limitations of Hubble's law are in the intrinsic motion of galaxies, the observed velocity will get influenced and the galaxy is orbiting due to the gravitational movement.

Example

Question: For some cluster, velocity measured as v = 103 km/s. What is the distance?

Solution:

Given that

Speed of the galaxy v = 103sup> km/s

Distance D = v/Ho

D = 1000/70.4

= 14.22 MPC

Therefore, the distance is 14.22 mega parsecs
