Detailed explanation-1: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.
Detailed explanation-2: -Rotation. Asteroids and comets rotate, but not exactly like the Earth. Because Earth is a sphere, its mass is distributed relatively evenly, so it rotates smoothly. Asteroids and comets aren’t uniformly shaped, so their rotation can be more of a tumble.
Detailed explanation-3: -Most asteroids are not strong, and when they disintegrate in the atmosphere they often produce a shower of meteorites on the ground. Comets are also small bodies orbiting the sun, but they also contain ices that produce a gas and dust atmosphere and tail when they get near the sun and heat up.
