Meteoroids



Meteoroids derived from an Asteroid. When asteroids are pulled inside the gravitational force of Earth collision occurs. Due to the force, asteroids splitted into tons of pieces. When the pieces of asteroids reaches the atmosphere some are burned completely. While it enters into the earth it becomes smaller in size. The pieces which left over are called meteorite. The pieces which fall from the sky are termed as “meteor shower”. The meteorite contains 92.8% composed of silicate stone, 5.7 percent composed of iron and nickel. It is also called as shooting star. Meteoroids travel around the sun in a variety of orbits and at various velocities. The fastest ones move at about 26 miles per second. Meteoroids also cause tiny damage to satellites. Most of the meteors are viewed visibly in the desert region.
