"Stars are very big and hot …

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. A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements. The Sun is the closest star to Earth.

Stars have their own heat and light. They have are very big and hot bodies of gases. The Pole Star is a bright star which always shines in the north direction. It helped the navigators to find the direction when the magnetic compass was not discovered.
