SOLAR SYSTEM

Detailed explanation-1: -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. So, when a comet gets close to the Sun, its ice and dust content start to vaporize.

Detailed explanation-2: -The Short Answer: Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth’s atmosphere, creating a streak of light in the sky.

Detailed explanation-3: -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.

Detailed explanation-4: -What is the difference between asteroids and comets? Comets are visible without a telescope. Asteroids are mostly rock and rock pieces, comets are composed of ice, gases, and dust.

Detailed explanation-5: -Specifically, comets and asteroids have much higher concentrations of iridium and other heavy metals than Earth’s crust has.
