Question

exclusive facts about stars and planets ​

Answer 1

Answer:

Explanation:

Our Sun is a star. It’s a vast ball made up of 74% hydrogen and 24% helium, with trace amounts of other elements. It has so much mass that the temperatures and pressures at its core are hot enough to ignite fusion. At the core of the Sun (and other stars), atoms of hydrogen are being fused into atoms of helium. This process releases a tremendous amount of energy. If an object isn’t performing some kind of fusion at its core, it’s not a star.
