What is a meteoroid? • It is the last but not the least discussion about our Space Rocks series. And for today’s video, we will learn the last category of space rocks, which is the Meteoroids. • Let us start with a quick recap of Space rocks. These are cosmic objects smaller than planets that orbit the sun. These are asteroids, comets, and meteoroids. In our previous videos about the Space Rocks series, we already talked about asteroids and comets. So, let us proceed with learning about meteoroids. • We initially talked about meteoroids briefly, which is its main comparison to the other space rocks is it is a smaller version of asteroids. Yes, meteoroids are similar to asteroids because it is also made of rocks or metals, yet they differ in size. Meteoroids can be as small as dust size up to as big as100 meters in diameter. If it is beyond 100 meters in diameter, it will be classified as asteroid. • Where do these dust size up to 100-meter diameter meteoroids come from? These are formed from the burning debris of comets and colliding asteroids. That is why if we closely examine its composition, it is similar to the component materials of terrestrial planets, just like asteroids and comets. The very tiny meteoroids or dust-size meteoroids are called micrometeoroids or cosmic dust. Just like the rest of the space rocks, they also do not emit light on their own, unless they reflect the light from the sun for example is the moon. Therefore, we could say that among the space rocks, meteoroids are hardly visible except for the larger ones or through using very powerful telescopes. • These meteoroids are the most frequent visitors to our planet. The moment they enter our atmosphere, they are now identified as meteors. They enter the Earth as fast as 42 kilometers or 26 miles per second which is twenty-eight times faster than an airplane. Traveling this fast could burn the meteor up to 1000 degrees Celsius due to friction with the atmosphere. The heat produces a tail of burning bright light which could make them visible especially at night. This is what we identify as ‘shooting star’, ‘falling star’, or ‘bulalakaw’ in Philippine terms. There are also meteors that burn brighter than the planets, these are what we call fireballs. There are certain occasions where we can see thousands of meteors within an hour and in near places, these are the most common spectacular night show, the meteor showers. • Enjoy this video about Meteoroids. • • #Meteoroids #EarthPen #EducationalVideo • CONTACT US • Email: [email protected] • Facebook Page: / earthpen • Youtube Channel: / @earthpen
