Explanation: 

Detailed explanation-1: -A star is a huge glowing ball of hot gas. Deep inside its core, hydrogen atoms smash together, forming helium and releasing huge amounts of energy that heats the gas. This is called nuclear fusion, and it’s why a star shines. As the hot gas pushes outward, it opposes the inward pull of gravity.

Detailed explanation-2: -The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.

Detailed explanation-3: -Most stars are made up of mainly two gases, which are hydrogen and helium.

Detailed explanation-4: -New stars are constantly forming in space. with stars, they are not actually on fire. The heat and light are released by the chemical process of atoms joining together.

Detailed explanation-5: -Hydrogen and helium are found in all stars. Ninety percent of all atoms in the universe are hydrogen atoms and fusion reactions fuel stars, resulting in the formation of helium and higher atomic number elements.
