Meteoroids

A meteoroid is a small rock or particle of debris in our solar system. They range in size from tiny grains to objects that are several meters in diameter. Meteoroids are the remnants from the formation of the solar system and can be found throughout the solar system. They are commonly composed of rock-forming minerals like olivine and pyroxene, as well as metals such as iron and nickel.

Characteristics of Meteoroids

• Size: Meteoroids can range in size from tiny particles to several meters in diameter.
• Composition: They are typically composed of rock-forming minerals and metals.
• Origins: Meteoroids can originate from comets, asteroids, or even the Moon and Mars.
• Speed: When they enter the Earth's atmosphere, they travel at extremely high speeds, often exceeding 25,000 miles per hour.
