There are countless number of objects in the universe orbiting the Sun. Asteroids and meteoroids are commonly known celestial bodies sharing few common things such as staying close to planets and orbiting the Sun. Well an asteroid is relatively small object composed of rock, metal or carbon. Asteroid are believed to be the leftover in the solar system. On the other hand, meteoroid is a small particle separated or accidentally detached particle of a comet or an asteroid.
Asteroids can also be called as minor planets of inner solar system. There are millions of asteroids in the asteroid belt. More than, 750,000 are found in the asteroid belt, which is located between the Jupiter and Mars. Asteroids can be as wide as hundreds of kilometers. Most asteroids are made of rocks, but with the latest explore some are found to be composed of iron and nickel.
Asteroids don’t have any atmosphere, but because of its enormous size they exert a gravitational pull. According to experts, few asteroids have one or two companion moons and two similarly sized asteroids orbit each other.
On the other hand, a meteoroid is a small rock composed of metal in a outer space. They are significantly smaller than asteroids with size ranging from a millimeter to a meter wide. When meteoroids enter the atmosphere of earth, they eventually vaporize completely and might never reach the surface. They burn during the descent and creates a light trail. Meteoroids are harmless but meteors in larger size tends to explode in the atmosphere can create shockwaves and can cause problems.
In simple terms, the difference between asteroids and meteoroids depends on the question of location. Asteroids are found in space. When it enters an atmosphere, it is known as meteor and when it hits ground it is known as meteorite. Basically all objects are made of rocks and minerals.
Difference Between Asteroid and Meteoroid
|Asteroids are minor planets.||Meteorit are falling star.|
|The orbital shape is elliptical and orbits the Sun||The orbital shape is elliptical and orbits the Sun but, get pulled into larger bodies.|
|Believed to be a leftover from the planet||Believed to be a smaller disintegrated element of comet or asteroid.|
|Do not have an atmosphere||Do not produce an atmosphere, but burn up when falling into a planet.|
|1 to more than 100 kilometer in diameter||Typically less than 10 meters.|
