WebHubble’s law formula is given in the following table: v = H 0 d. Where, v is the velocity of the galaxy in km/s. H 0 is the Hubble constant in km/s/Mpc. d is the distance of the galaxy in Mpc. A megaparsec is a unit of measurement equal to one million parsecs or 3.26 million light years. Mpc is a common expression for megaparsec. WebRecessional velocity. Recessional velocity is the rate at which an extragalactic astronomical object recedes (becomes more distant) from an observer as a result of the expansion of the universe. [1] It can be measured by observing the wavelength shifts of spectral lines emitted by the object, known as the object's cosmological redshift .
