What is metioro?

It is unclear what you mean by "metioro." If you meant "meteor," here is some basic information:

A meteor is a space rock that enters the Earth's atmosphere and burns up. It is also called a "shooting star." Most meteors are very small and burn up completely before they reach the ground. Those that do make it to the surface of the Earth are called meteorites.

Meteors are created when small pieces of rock, dust, or ice called meteoroids collide with the Earth's atmosphere at high speeds. As they move through the atmosphere, the friction between the meteoroid and the air causes it to heat up and vaporize, creating a streak of light that we see as a meteor.

Meteor showers occur when the Earth passes through a trail of debris left behind by a comet. The debris burns up in the atmosphere, creating a display of many meteors in the sky. Some famous meteor showers include the Perseids, the Leonids, and the Geminids.
