Journey Through Space
Meteorites are fascinating objects that have traveled through space before landing on earth. Their journey begins as meteoroids, small rocky or metallic fragments that orbit the sun. Upon entering earth’s atmosphere, meteoroids experience intense heat due to friction, causing them to burst into flames and create a fiery display known as a meteor.
Surviving this fiery entry, some meteoroids manage to reach the earth’s surface. The path a meteoroid takes through space and its ultimate fate as a meteorite depend on various factors such as the angle of entry, speed, and composition. Scientists study meteorites to gain insights into the origins of our solar system and the processes that shape celestial bodies.
Through these investigations, we can deepen our understanding of the universe and the fascinating entities that traverse it.
