An illustration of a HertzsprungRussell diagram for the set of stars that features the Sunshine (Middle) (see Classification) The time a star spends on the leading sequence is dependent totally on the quantity of fuel it's got and the rate at which it fuses it. The Solar is anticipated to Reside ten billion (1010) a long time. Massive stars take in their fuel pretty speedily and are small-lived. Minimal mass stars take in their gas very bit by bit.
