What are the main sources of meteoroids?

Answer 1

1. Interplanetary debris that was not gravitationally swept up by the planets during the formation of the solar system.

2. Material from the asteroid belt.

3. The solid remains of comets that once traveled near Earth's orbit.

Answer 2

The question of, the "main" sources, of meteoroids, has been answered (e.g., cometary debris, asteroids, and asteroidal collisions). I thought it would be helpful to mention the origin of all of these - the coalescence of, 'free-floating', matter, and gases, produced, by self-gravitational, 'collapse' (coalescence).

Slicate, mineral, and metallic particles are produced by supernovae events ('Population-II' stars; zero-metallicity - mainly, hydrogen gas). Metals, and other elements, are created under high pressures, and temperature, when one of these stars explodes, and, then, spreads this material into the Interstellar Medium, eventually, to re-coalesce into 'Population-I' stars (high-metallicity). The materials that, ultimately, form, 'meteoroids', are created at the cores of, exploding, Pop-I stars. The 'ejecta' from these explosions is dispersed into, otherwise, nearly, completely, empty space (interstellar space), forming interstellar clouds called, 'molecular' clouds. When particles in these clouds collect, together, gravitationally, they have a common center of gravity, which continuously collects, more, and more particles - ultimately, to form, what we think of, as, large, objects (asteroids, meteoroids, moons, planets). Any of these masses can collide, with any other, and eject smaller fragments of themselves into local, nearby, space. When any of these particles, rocks, boulders, etc., come under the gravitational pull of a larger object - such as, the Earth -they succumb to gravitational pull, and, they may, ultimately, become 'meteorites' - "grounded" meteoroids, asteroids, dust particles. A 'meteoroid', is any particle with a diameter of 1-meter, or, smaller. An, 'asteroid', is any particle, larger than 1 meter, up, to almost, planetoid-sized, asteroids. At this point, such an object would undergo, gravitational, collapse. Given enough mass, the object would also reach hydrostatic-equilibrium, and assume a spheroidal shape.

Well, that's about as far as I'm going to go with this one!

Answer 3

Meteoriods, space rocks that are floating around in space and orbiting the Sun, probably formed of "left-over" material that was never incorporated into one of the planets, or condensed in smaller pieces somewhere in the solar system. Many of them were, once, bound together with ice as part of a comet; many others were part of larger bodies that collided and broke apart. A recent Hubble picture shows the debris pattern resulting from two larger asteroids colliding in the asteroid belt.

Some research indicates that the impactor that struck the Earth 65 million years ago (and caused the extinction of the dinosaurs) probably came from a asteroid collision millions of years earlier.

Answer 4

Meteors occur in showers, which arise when the Earth passes through a trail of debris left by a comet, or as "random" or "sporadic" meteors, not associated with a specific single cause. Remember movies like "Asteroid", "Armageddon"- in both films meteor arised cause Earth's and meteor's orbits intersected

Answer 5

There is no one, certain origin, but there are a number of various origins. One could be debris from a large impact of two planets or asteroids, or other rocky body.
They are bits of the debris left over from the formation of the solar system. Many are the debris resulting from collisions between larger (differentiated) bodies that were forming with the primitive solar system.
Meteoroids are rocky or metallic objects traveling in space. They are mostly small splinters that come from asteroids or comets.
Meteoroids are material left over from the formation of the solar system that did not become part of the sun or any planet.
Comets or asteroids trust me I know my science and it's weird but its right

between Jupiter and Saturn

Answer 6

debris that wasn't swept up by gravity itself

Answer 7

A meteorite comes from outer space. A meteorite is formed when an asteroid breaks up and the particles go shooting across the sky.

Answer 8

They can be dirt or dust in space or the debris from things like comets or other objects in space. When we pass through a trail of this material we get meteor showers.

Answer 9

Some meteoroids form when asteroids collide in space. Others form when a comet breaks up and creates a cloud of dust that continues to move through the solar system.

Answer 10

comets and asteroids
