Question

Differentiate star and planet

Answer 1

Star-They have their own light .They are far away from earth and they twinkle.
Planets-They reflect light from the sun.They are closer to earth and they do not twinkle.

Answer 2

 Stars are balls of gas that are so massive that the pressure inside of them causes a nuclear reaction. That makes them bright and hot.

Planets can vary a bit, and I don't know the exact definition. Planets like the earth and Mars are rocky with a metallic center -- in other words, they're solid. But planets like Jupiter and Saturn are mostly gas, like a star. The difference is that they aren't big enough to cause the nuclear reactions, so they aren't so hot and don't emit much light
