Detailed explanation-1: -When a meteoroid enters Earth’s upper atmosphere, it heats up due to friction from the air. The heat causes gases around the meteoroid to glow brightly, and a meteor appears. Meteors are often referred to as shooting stars or falling stars because of the bright tail of light they create as they pass through the sky.
Detailed explanation-2: -A meteor is made up of bits of dust and rock that broke away from colliding asteroids, comets, or planets. Most of these chunks of rock and metal burn up in the Earth’s atmosphere and become meteoroids.
Detailed explanation-3: -Some people call them shooting stars. Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
Detailed explanation-4: -Most meteorites found on Earth come from shattered asteroids, although some come from Mars or the Moon. In theory, small pieces of Mercury or Venus could have also reached Earth, but none have been conclusively identified. Scientists can tell where meteorites originate based on several lines of evidence.
