Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A star is classified as variable if its apparent brightness as seen from Earth changes over time, whether the changes are due to variations in the star's actual luminosity, or to variations in the amount of the star's light that is blocked from reaching Earth. Many, possibly most, stars have at least some variation in luminosity: the energy output of our Sun, for example, varies by about 0.1% over an 11 year solar cycle, equivalent to a change of one thousandth of a magnitude. Astronomers use the term millimagnitude, abbreviated as mmag, for one thousandth of a magnitude.
