A star with mass greater than 0.4 times the Sun's will expand to become a red giant when the hydrogen fuel in its core is exhausted.Other characteristics of a star, including diameter and temperature, change over its life, while the star's environment affects its rotation and movement.A plot of the temperature of many stars against their luminosities produces a plot known as a Hertzsprung–Russell diagram (H–R diagram).William Herschel was the first astronomer to attempt to determine the distribution of stars in the sky.During the 1780s he established a series of gauges in 600 directions and counted the stars observed along each line of sight.Plotting a particular star on that diagram allows the age and evolutionary state of that star to be determined.


In 1584 Giordano Bruno suggested that the stars were like the Sun, and may have other planets, possibly even Earth-like, in orbit around them, By the following century, the idea of the stars being the same as the Sun was reaching a consensus among astronomers.
