What is the relationship between a galaxy's recessional velocity and its distance from Earth as per Hubble's Law?

  • The velocity increases with distance

  • The velocity decreases with distance

  • There is no relationship

  • The relationship is yet to be discovered

Answer

Hubble's law states that the velocity of a galaxy's recession from Earth is proportional to its distance from Earth. In other words, the farther away a galaxy is, the faster it is moving away from us. This relationship is often expressed as the formula v = Hd, where v is the recessional velocity of the galaxy, H is the Hubble constant, and d is the distance to the galaxy.
