A planet and a comet are both celestial bodies that orbit around a star. They are alike in that they are both part of our solar system and are affected by the gravity of the sun and other celestial bodies.
They are different in several ways:
A planet is typically much larger and more massive than a comet.
Planets have a definite shape, whereas comets have a loose collection of dust and ice particles held together by gravity.
Planets have a regular, nearly circular orbit around the sun, whereas comets have highly elliptical orbits.
Comets are composed of ice and dust, and as they come closer to the sun, they heat up, and the ice turns into gas, creating a cloud around the nucleus called a coma, and a tail, which points away from the sun because of the solar wind pushing the gas and dust.
Planets are mostly solid and have a thick atmosphere.
Planet mostly reflect the light of the sun, while Comets emit light by the solar radiation on their surface.
