What is the Star?
Star is a huge sphere of glowing gas and its very hot. One of those closest Stars to the Earth is called Sun.
Stars produce their own light and energy by process called nuclear fusion. Stars classified by the color as: blue, orange, red and white. They are sorted by sizes as: small, medium, giant and super giant. The luminosity is how bright Star is, also sorted by the numbers from 0.0001 to 1,000,000. And temperature of the Stars from 2,000 to 50,000 (T,K). Stars also has different ages like young, middle age and old stars. Scientists use "Spectral Class" to sort and show the difference of size, luminosity, and color of the Star.

There many different types of Stars as: White Dwarf, Main Sequence, Giants, and Super Giants. White Dwarfs Stars are very small, hot, dim, and they are old Stars.
Main Sequence Stars. They are different colors, different temperature, different sizes, and with different luminosity such as: Bright and Dim Stars. Giant Stars. They are huge, bright with lowest temperature, and they also have different colors. Super Giant Stars are really huge with lowest temperature, and highest luminosity.
H-R Diagram
The Hertzsprung-Russell Diagram is used by scientists to measure how far or close objects are to the Earth. It also helps astronomers to classify the temperature, luminosity, color, and the size of the Stars.
Nuclear Fusion
Nuclear fusion is the process by which multiple atoms having the same charge two atomic nuclei join together in order to form a heavier nucleus. Like Hydrogen atoms fused together to form a Helium atom. The Formula of Nuclear Fusion is
2H→He+ Energy
The Life Cycle of a Star
Every single Star have age like humans, they all born and they all dies. Stars begin to form from clouds of gas and dust, and this process called Stellar Nebular
Here is the life cycle of Sunlike Star:
Stellar Nebula - Sun Like Star - Red Giant - Planetary Nebula - White Dwarf - Black Dwarf
Here is the life cycle of Huge Star:
Stellar Nebula - Huge Star - Super Giant - Supernova - Neutron Star
This also life cycle of Giant Star:
Stellar Nebula - Giant Star - Super Red Giant - Supernova - Black Hole
