Brightest Stars in the Sky

This is a list of stars arranged by their apparent magnitude - brightness as observed from Earth.
The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A star of magnitude 2.0 is 2.512 times brighter than a star of magnitude 3.0, 6.31 times brighter than a star of magnitude 4.0, and 100 times brighter than one of magnitude 7.0.
Some are binary star systems which appear to be a single star when viewed with the naked eye.
