The Galaxies Receding Speed Calculator will calculate the:

- Receding speed of a galaxy when its distance from us (expressed in megaparsecs) is known

**Calculation Parameters:** The Milky Way is assumed as centre of the Universe The calculations allow for the margin of error in the Hubble's Constant

Receding speed of galaxy (v) = km/s [kilometer per second] |

Receding speed of galaxy calculation |
---|

v = H_{0} × rv = × 2.4/73.8v = × v = |

Galaxies Receding Speed Calculator Input Values |

Distance of the remote galaxy from Milky Way (r) Mpc [megaparsec] |

Hubble's Constant (H_{0}) km/s·Mpc [kilometer per (second · megaparsec)] |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each galaxies receding speed calculation, the Galaxies Receding Speed Calculator will automatically calculate the results and update the Physics formula elements with each element of the galaxies receding speed calculation. You can then email or print this galaxies receding speed calculation as required for later use.

We hope you found the Galaxies Receding Speed Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe.
