Stars get most of their energy through nuclear fusion. Mainly, the fuse hydrogen to helium. However, many stars will eventually fuse helium to the so-called "metals", meaning any element heavier than helium.
Most stars, for most of their existence, fuse hydrogen into helium.
Mainly its mass. The most massive stars develop the most quickly.
Stars are formed when elevation gass escapes the sun. They will then catch heat from planets, the planets orbit will then place the stars in a special order. Then the star will glow for 10,000 years then will die.

Because the sun is brighter than stars
Stars generally get their energy from hydrogen. By far the most common source of energy from a star (like our sun) is the nuclear fusion of hydrogen atoms into helium. As long as there is enough hydrogen, and other elements, to support the nuclear fusion, the process will go on. Therefore, stars generally get their energy from large amounts of hydrogen which coalesced during the star formation and through gravity received enough mass (weight) to start the nuclear process.
More white dwarves. Most stars will become white dwarves at the end of their lifetime. On a "select few" will become black holes - the most massive stars.
What Is The Most Exiting Thing that happend
Genghis Khan killed 20 million people during his lifetime.
Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion.

The lifetime of a star varies a lot, depending on its exact mass. The lifetime of a star can be anywhere from just a few million years for the most massive stars, to trillions of years for red dwarves.
