Planet vs. Star

A large body orbiting a star versus a massive ball of hot plasma that emits light from nuclear fusion.

The comparisoni

✗ Wrong

The Sun is a planet.

✓ Correct

The Sun is a star — it generates its own light through nuclear fusion. Planets (like Earth) orbit stars and only reflect their light.

The ruleii

PLANET = orbits. STAR = fuses.

STAR is a massive ball of hot plasma sustained by nuclear fusion — emits its own light (sun, Alpha Centauri). PLANET is a smaller body orbiting a star, does not fuse, and reflects starlight. Earth is a planet; the Sun is a star.

Memory aidiii

Remember it like this

Stars fuse. Planets reflect.
