A comet orbits the sun and an asteroid does not

|
An asteroid is formed from leftovers from the formation of the solar system and a comet is not

|
When a comet comes near the sun it loses material while an asteroid typically remains solid

An asteroid orbits the sun in the oort cloud while a comet orbits the sun between Mars and Jupiter

Detailed explanation-1: -Asteroids were formed much closer to the sun where it was impossible for the ice to remain solid. Comets were formed farther away from the sun where the ice remained solid. Comets that approach the Sun lose material with every orbit around it as its ice melts and vaporizes to form the tail known as the coma.
Detailed explanation-2: -Asteroids are small rocky planetoids. while comets are formed of frozen gases held together by rocky and metallic material.
Detailed explanation-3: -When a comet’s orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of miles.
Detailed explanation-4: -Near-Earth asteroids (NEAs) have Earth-like orbits, so their collisions with Earth tend to be glancing blows from behind or from the side. But comets travel around the sun in more random paths and can thus slam into the planet head-on, with potentially catastrophic results, researchers say.
Detailed explanation-5: -The main difference between comet and meteor is that a comet is a cosmic object made of ice, gases, rock and dust that orbits the Sun while a meteor is a meteoroid that has entered the Earth’s atmosphere. Meteors, meteoroids, meteorites, and asteroids are all objects that originate in the space.
