Calculating distance using absolute and apparent visual magnitudes

  1. Jul 6, 2010 #1
    Is there an equation for calculating the distance of a star if you have the values for apparent visual magnitude and absolute visual magnitude?

    You can use

    [tex]\log D = \frac{m-M}{5}+1.513[/tex]

    Where:
    M is absolute magnitude
    m is apparent magnitude
    D is the distance in light years.
