Ramesh Singh's video: Stars Size Comparison: Hottest Coolest Nearest Stars to Earth and More

Star is a hot ball of plasma held together by its own gravity. Stars are born inside hydrogen-based dust clouds called a nebula. When the hydrogen clouds collapse due to gravity, material at the center begins to heat up, as a result, a Protostar is born. Protostar is a very young star that is still gathering dust and gas from its molecular cloud. For a star like our sun, this protostellar phase lasts about 500,000 years. As the compression of hydrogen gas continues, the core becomes so hot that the process of nuclear fusion starts, where hydrogen atoms fuse to form helium. In this process, some matter is lost which is converted into energy, and a star is born. This relation of matter and energy was discovered by Albert Einstein by his famous formula E=mc^2. Where E is energy, m is the mass, and c is the speed of light. Check out the video for more information and explore the coolest, hottest, brightest, largest, smallest, variable, and nearest star to earth.
