How are most meteoroids formed?

Answer 1

Meteorites begin as asteroids, which are loose rock in space formed either from pre-planetary accretion, or from impact with larger bodies such as planets or moons. Asteroids are attracted to Earth because of it's gravitational pull. When the asteroid enters Earth's atmosphere it becomes a meteoride, when it lights up due to friction it becomes a meteor, and when it hits Earth's surface, it is called a meteorite.

Answer 2

For clarification, meteoroids are the lumps of stuff that falls into earth atmosphere and either disintegrates & burns up there or lands on the earth some place. Theyre also known as 'shooting stars' giving a characteristic trail as they burn up, lasting only a few seconds.

They are formed like all the other planets, moons & asteroids. After formation of the sun, debris was left over that orbited it, this debris came to circulate in line with the rotation of the sun and all rotated in one direction due to gravitational effects. The debris was now in a dispersed ring around the sun, gravity caused the debris to conglomerate & come together in clumps, similar to the way eddies in streams spiral into themselves while remaining in orbit. These clumps got large enough eventually to have a significant gravity of their own and started to mop up the remaining debris of the solar system, these large clumps became the planets. But, smaller clumps left over, were free to have their own orbits, and there is a vast number of these, billions, in the solar system, mainly centered around the asteroid belt but they also inhabit different areas and can have eccentric orbits, also interaction with the gravity fields of some planets like Jupiter can cause them to fly off course. They can end up in line with earth's orbit and as such they come to collide with the Earth.

tldr: gravity

Answer 3

Meteor showers are formed when the Earth goes through a debris field left by a comet or asteroid.
