    Apparent magnitude of star:

    Apparent magnitude of a star is how bright it appears on earth.

    Absolute magnitude of star:

    Absolute magnitude of star is how bright it appear from a distance of 32.6 light years from earth.

    Due to farthest distance of star from earth, it appears smaller. But when we look at it from near it will appear greater in size or magnitude. That is why, we can say that absolute magnitude of some stars is greater than their apparent magnitude.
