Calculate Recessional Velocity





Formula

The formula to calculate the Recessional Velocity (Vr) is:

\[ Vr = H \times D + Vpec \]

What is Recessional Velocity?

Recessional velocity is the speed at which astronomical objects recede from an observer due to the expansion of the universe. It is calculated using the Hubble constant, the proper distance, and the peculiar velocity of the object.

Example Calculation

Consider an example where:

Using the formula to calculate the Recessional Velocity:

\[ Vr = 342000 \times 1000000 + 10000 = 342000000000 + 10000 = 342000010000 \text{ MPH} \]

This means that the recessional velocity for this example is approximately 342,000,010,000 MPH.
