Smaller, cooler stars like red dwarfs have the longest life spans of up to trillions of years because they burn their fuel slowly. In contrast, massive stars like blue giants have much shorter life spans of only a few million years.
Suns
Smaller stars, such as red dwarfs, have the longest life spans, on the order of tens to hundreds of billions of years. Larger stars, like blue giants, have much shorter life spans, typically only a few million years.
The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.
The starting mass of the longest living stars, known as red dwarfs, is around 0.1 to 0.5 times the mass of the Sun. These stars have a very slow rate of nuclear fusion and can live for tens to hundreds of billions of years.

Main sequence
Smaller stars, such as red dwarfs, have the longest life spans, on the order of tens to hundreds of billions of years. Larger stars, like blue giants, have much shorter life spans, typically only a few million years.
White dwarf stars are theorized to be the final evolutionary state of all stars that did not become neutron stars. This stage is the longest in a stars life outside of black dwarfs which are white dwarfs that have cooled dramatically.
The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.

The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
The main sequence phase represents the longest period of time in a star's life cycle, during which the star fuses hydrogen into helium in its core. This phase can last billions of years, depending on the mass of the star.
The Longest Day
Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.
The stars that are spaced less than your latitude from the celestial pole never set.
The longest life span of a buffalo is 45 years.
