Calculate the recession velocity of a galaxy or its distance from Earth using Hubble's law. This fundamental relationship shows the universe is expanding and provides a method to measure cosmic distances.
Enter your values below
Distance to the galaxy in Megaparsecs
Velocity at which the galaxy is moving away
Current value ≈ 70 km/s/Mpc
How this calculator works
Recession velocity equals Hubble's constant times the distance to the galaxy. H₀ ≈ 70 km/s/Mpc.
