How do a star and a planet different?

Answer 1

Stars have motion "left over" from the Big Bang; also, they are affected by the gravity of other stars, so that most are circling galaxies. In addition, stars can be affected by the shock waves of nearby novae and perturbed by their own planets and passing stars and dark bodies.

Remember the Second Law of Motion: stars are massive and space is largely empty, so a star in motion isn't slowed down by having to buck the medium, as all Earthly objects do when they pass through the air (or water).

Answer 2

Because the stars do not move, they only appear to move because the earth is moving. So this causes the other planets and the stars appear to be moving differently, like when you are riding in a car the other cars would be the planets and the light posts and trees would be the stars.

Answer 3

Stars are usually large, and they are made up of gas that is constantly fusing in a chemical reaction to make heat, light, and energy. Planets are completely different, and they usually orbit around stars.

Answer 4

A star gives of large amounts of heat and light. It does this because it has nuclear fusion reactions going on inside it.

A planet only shines by reflected light from its star. In our solar system that star is the Sun.

Answer 5

Every star has its own "proper motion", and some of them are moving pretty quickly - but the stars are so far away that the apparent motion even over the course of decades is unnoticeable. The planets move more slowly, but are relatively close; close enough that we can see the change in position from one night to the next.

Answer 6

A star is a luminous sphere of plasma held together by its own gravity, primarily powered by nuclear fusion in its core, whereas a planet is a celestial body that orbits a star, does not produce its own light, and is typically composed of rocks, gases, or ice. Stars emit light and heat, while planets reflect light from their star.

Answer 7

Planets do not emit light, they reflect it. Furthermore, stars are much more massive, more than a thousand times the mass planets.

Answer 8

Stars are basically big burning balls of gas that give off light/heat. Our sun is an example of a star. Planets, like earth, is a body that moves around (orbits) a star.
