The asteroid is a small star-like body that is also called a minor planet or planetoid. It does not cause a major impact as it mostly burns up before hitting the ground or fall into the ocean as the major portion of the earth consists of oceans. The hitting of an asteroid would cause a major impact on the earth with a change in the climate and diversity of the affected area. It does not have gravitational pull and burns up before falling on any other surface.

It exerts a gravitational pull due to its enormous size. The meteoroid also does not produce an atmosphere The asteroid does not have any atmosphere. It also has elliptical orbit but gets pulled easily into larger bodies like planets due to its mass. It follows elliptical orbit such that its distance from the sun does not differ very much. It is a smaller body with a size range of fewer than 10 meters in diameter. It is a larger body with size 1 to more than 100 kilometers in diameter. It made up of rocky substances with metals on its outer surface. It usually made up of rocky substances, but some are also composed of nickel and iron. The meteoroids believed to be originated from the disintegration of the comet. It believed to originate from the remanents of planets that fell apart. The asteroid is also called a planetoid or a minor planet. The meteoroid is not so significant to get named. The phenomenon is called a meteor shower.Shaped like a star Comparison Chart AsteroidĪ solid object, moving in the solar system that has a size smaller then planets but more extensive than meteoroids, is known as an asteroid.Ī solid object, moving in the solar system that has a size smaller then asteroid but larger than an atom, is known as a meteoroid. When meteoroids enter the earth’s atmosphere at extremely high speeds in parallel trajectories, the meteors formed as a result are observed to radiate or originate from one point in the night sky.When meteoroids enter the atmosphere of the Earth, they vaporize completely and might never reach the surface.The fastest meteoroids move at about 42 kilometers per second.Meteoroids revolve around the sun at various speeds.Meteoroids are pieces of interplanetary matter that are frequently only the size of millimeters.Almost all asteroids are irregularly shaped although some of the large ones are nearly spherical.Asteroids are rocky bodies that do not have an atmosphere but because of their size, they have a gravitational pull.

Asteroids are also known as minor planets or planetoids of the inner solar system.

They are typically less than 10 meters in diameter. Their size ranges from 1 km to more than 100 kilometers in diameter. They do not have an atmosphere but burn up when entering the earth’s atmosphere. They are rocky bodies that do not have an atmosphere. They are believed to be small disintegrated elements of a comet or asteroid. They are believed to be leftovers from the planetesimal bodies within the sun’s solar nebula. They orbit the sun and their orbital shape is elliptical. They orbit the sun and their orbital shape is elliptical There are also other types of asteroids made up of rare compositions. They seem like they are made up of nickel-iron. They make up most of the rest of the asteroids. They are reddish color asteroids that dwell in the middle region of the main asteroid belt. They appear to be made of silicate materials and nickel-iron and account for almost 17% of known asteroids. They are greenish and reddish asteroids that dominate the inner asteroid belt. They probably consist of clay and stony silicate rocks and include more than 75% of known asteroids. They are most common grayish-colored asteroids that inhabit the main belt's outer regions. Currently, the known asteroid count is 1,113, 527.Īsteroids fall into three categories based on their composition. They are said to be remains of planetesimal bodies within the sun’s solar nebula which never grew to become full-grown planets. They are rocky bodies that do not have an atmosphere but because of their size, they have a gravitational pull. There are millions of asteroids in the asteroid belt. They are found mainly in the asteroid belt between Jupiter and Mars. Key Terms: Meteoroids, Asteroids, Asteroid belt, Apophis, Trojan asteroids, Dwarf planet ceresĪsteroids are also known as minor planets or planetoids of the inner solar system.
