|
|
Asteroids’ orbit is more rounded and less elliptical than comets

|
|
They have the same orbit

Detailed explanation-1: -Most asteroids are found in a ring between the orbit of Mars and Jupiter called the asteroid belt. Some asteroids are round, some are elongated, and some even have a satellite. A comet also orbits the Sun, but unlike an asteroid, it’s composed of ice and dust.
Detailed explanation-2: -Planets have a low eccentricity, that is they are very circle-like. They are not very elliptical. Comets have highly elliptical orbits-an oval with the Sun near the very end of one ellipse. They often have parabolic, or open, orbits meaning they may not return to the same position again.
Detailed explanation-3: -As they revolve around the Sun in elliptical orbits, the asteroids also rotate, sometimes quite erratically, tumbling as they go.
Detailed explanation-4: -An asteroid is a small rocky object that orbits the Sun. A comet is a ball of ice and dust that obits the Sun. A meteoroid is a small piece of an asteroid or a comet. A meteor is a streak of light in the sky that appears when a meteoroid burns up upon entering Earth’s atmosphere.
Detailed explanation-5: -Comets and asteroids have a lot in common. Both orbit the sun. Both are far smaller than the planets. Both are remnants of the solar system’s formation almost 5 billion years ago.
