Question

Short note on meteorids

Answer 1

Small chuncks of stone that are capable of intersecting Earth's orbit. When a meteoroid enters Earth's orbit it is known as a meteor or "shooting star." If it doesn't entirely disintergrate into the atmosphere and strikes the surface of the Earth it is called a meteoroite. They travel at high speed when it enters Earth's atmosphere and the friction they encounter heats the surrounding area. Atoms and Moleclues get exited and the atmosphere becomes luminescent

Answer 2

Hey ! here is your answer


A meteoriod is a small rocky or metallic body in outer space . Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust . Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars . When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km/s (72,000 km/h; 45,000 mph),
aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a
meteor or "shooting star". A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower . If that object withstands ablation from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a
meteorite .
An estimated 15,000 tonnes of meteoroids, micrometeoroids and different forms of space dust enter Earth's atmosphere each year.
