Detailed explanation-1: -Stars are huge balls of burning gases, most of which are made of hydrogen. As the hydrogen gas in a star is squeezed due to gravity, it produces huge amounts of energy, which make it glow. The size, temperature, brightness, and color of stars vary. The color of a star is determined by its temperature.
Detailed explanation-2: -Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
Detailed explanation-3: -Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.
