The Stellar Distance Based on Magnitude calculator computes the approximate distance to a star based on the apparent magnitude of the star (m) and the absolute magnitude of the star (M).

INSTRUCTIONS: Enter the following:

  • (m) This is the apparent magnitude of the star.
  • (M)  This is the absolute magnitude of the star.

Stellar Distance (d): The calculator returns the approximate distance to the star in parsecs.  However, this can be automatically converted to other distance units (e.g. kilometers or light years) via the pull-down menu.

The Math / Science

The formula for the distance to a star based on it apparent and absolute magnitude is:

d = 10(m-M+5)/5
