A star undergoes nuclear fusion in its core and emits light, a planet does neither. The planet orbits, while the star is at the focus of the elliptical orbit.

Stars are huge balls of hydrogen and helium which glow as they fuse into heavier elements. The sun is a star. The other stars you see in the sky at night are similar, but are trillions of miles away. A planet looks like a star at night, but it's actually a body closer to the size of the earth (much smaller than a star) which orbits a star. All the planets we can see orbit the sun and, along with the earth, make up the solar system.

Stars are a collection of burning gases that give off light, some with planets orbiting and some without. A planet is a body that orbits a star. They generally have atmosphere and they only reflect light. In the night sky, if you look up you can see the difference. The light from a star "twinkles" while the light from a planet is steady.

Stars are hot balls of gases fueled by nuclear fusion of lighter elements into heavier ones. Planets can be either made of light elements like hydrogen or helium just like stars but too small to sustain nuclear fusion or heavier solid material like the earth. Planets can be distinguished from smaller bodies like asteroids because they gravitationally dominate the volume of space they occupy as they orbit their parent star or any body in the Solar System that is more massive than the total mass of all of the other bodies in a similar orbit, unlike asteroids that will share the same orbital region of space (like the asteroid belt between Jupiter and Mars and the Kuiper Belt beyond the orbit of Neptune). That is why Pluto is no longer considered a planet because it has not collected the left over debris/asteroids in its path like the other planets has done.

Stars are generally very much larger than a planet and they burn atomic fuel and therefore emit their own light. Planets shine by reflected light only and orbit around the stars - to put it very simply

The difference between a star and planet...
Star - A celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior.
Planet - Any of the nine large celestial bodies in the solar system that revolve around the sun and shine by reflected light. For example Mercury, Venus...etc.

Effectively Mass. A planet does not undergo fusion whilst a star does.

A star is a HUGE burning ball of gas, and a Planet is a giant floating rock.

A star is a massive, luminous ball of plasma that is held together by its own gravity...... a star shines due to thermonuclear fusion
Planets circle the star. They can be either rocky or gaseous in composition.

a star is a huge heat mass (ex sun). planets are masses of rock, gas, etc. that orbit a star

Stars revolve around the earth but planets wander in the heavens.
