EVERYDAY SCIENCE

Detailed explanation-1: -A star is a huge glowing ball of hot gas, mainly hydrogen and helium. The temperature is so high in its core that nuclear fusion occurs, producing energy. Stars are in equilibrium between the inward force of gravity and the outward force of pressure.

Detailed explanation-2: -Only the Sun can generate its own light in the Solar System; all the other astronomical objects shine by reflected sunlight. The Moon reflects the light from the Sun as well. (See the term “star” in the Glossary.)

Detailed explanation-3: -Because planets do not have nuclear fusion, they do not produce their own light. Instead, they shine with light reflected from a star. When we see planets in the night sky, such as Venus, the so-called “Evening Star, ” we’re seeing reflected sunlight.

Detailed explanation-4: -Stars Don’t Just Produce Light – They Reflect It Too, And No One Noticed Until Now. We tend to think of stars as the objects that make most of the light in the Universe, while planets, moons, rocks, dust and gas reflect this starlight.
