3. Meteoroids

Meteors enter the Earth’s atmosphere at a very high speed and get heated up due to friction in the atmosphere. This small object glows and evaporates quickly like a bright streak for a short time. These bright streaks of light, which is visible in the night sky, are called meteors. It is also known as shooting stars.

 

When Earth crosses the leftover of a comet, groups of meteors are seen. These meteors fall on Earth like a shower and are known as meteor showers. They occur at regular time intervals in each year. The time of their visibility is found through a scientific magazine.

 

Sometimes, the large meteors can reach the Earth before they evaporate completely. They are known as a meteorites. These objects help scientists to understand the nature of the material from which the solar system was formed.

 

 

Every year, around $3000$ meteorites fall on different parts of the Earth. The Hoba Meteorite in Namibia is the largest discovered meteorite, which is mainly made up of iron.
