    Alnilam is the brightest star

    Absolute brightness is how bright the star actually is. Apparent brightness is how bright the star looks.

    Factors that influence how bright a star looks is distance. The fact that Alnilam has the same apparent brightness of the other two stars even though it is farther away, means that it is brighter.
