Meteoroid
A meteoroid is a relatively small (sand- to boulder-sized) fragment of debris in the Solar System. When entering a planet's atmosphere, the meteoroid heats up and partially or completely vaporizes.

History
A meteoroid is a piece of astronomical debris, smaller than an asteroid.
Meteoroids and Space Debris Activity
Meteoroids and space debris present a potential hazard to astronauts and spacecraft. This activity demonstrates the penetrating power of a projectile with little mass but with high velocity.
The fastest meteoroids travel at roughly 26 miles per second (42 km per second) through space.
Spacecraft Damage from Meteoroid
Meteoroids have done minor damage to spacecraft, including the Hubble Space Telescope (HST).
Definition: Meteoroid: A small rocky object orbiting the Sun; smaller than an asteroid. Also: Meteoroid; A piece of stone or metal that travels in outer space.

General considerations. The solar system contains many small bodies that move in orbits sufficiently eccentric to cross over and intersect the orbit of the Earth.

Isn't that amazing?
Meteoroids burn up in the atmosphere and fall to the Earth as dust. Every day, approximately 3000 metric tons of dusty space material falls to Earth.
Micrometeoroid. Very fine grains of space dust are called micrometeoroids.

Meteoroid
A meteoroid is a small chunk of material typically from a comet, asteroid, or ejecta material from a planetary impact. When a meteoroid enters the Earth's atmosphere and becomes visible, it is known as a meteor (or shooting star).

The meteoroids in the meteor stream are basically travelling parallel to each other, but to an observer in the middle of the stream, the meteors fall to the left and right, behind and in front of him.
Most meteoroids crumble and disintegrate completely before they reach an altitude of 80 km (50 miles).
The average meteoroid enters the atmosphere at between 10 and 70 km/sec. But all but the very largest are quickly decelerated to a few hundred km/hour by atmospheric friction and hit the Earth's surface with very little fanfare.

The track of the meteoroid in this image is only about 0.05 inches long. The meteoroid itself has a diameter of only about 1/1000 of an inch and has come to rest just beyond the narrow end of the track in the upper right (the small white dot).

Earth scoops up meteoroids on the dawn side of the planet and outruns them on the dusk side.
To produce a meteor a meteoroid needs only a mass of one millionth of a gram, but needs to be travelling at a tremendous speed: anywhere between 11 and 74km/sec (that is up to 100 times faster than a rifle bullet).

Meteoroids moving at any speed can hit the atmosphere. Before midnight your local part of the Earth is facing away from the direction of orbital motion, so only the fastest moving meteoroids can catch up to the Earth and hit the atmosphere.
The planets are still growing slowly as comets and meteoroids collide with them. Events such as the 1994 impact of Comet Shoemaker-Levy 9 into Jupiter remind us that the Under Construction signs in our solar system can't be taken down just yet.
(c) A solid portion of a meteoroid that has reached the earth's surface. There are three types of meteorites - stony, iron, and stony-iron meteorites - and they range in size from microscopic to the size of an asteroid.
There are no small craters because small meteoroids burn up in the dense atmosphere before reaching the ground, and the bunching of craters suggest that large meteoroids usually break up before reach the surface.
Incidentally, just before a rock fragment enters our atmosphere, it is called a meteoroid. While it is traveling through the atmosphere and is visible as a shooting star, it is called a meteor.
a small planetary body in orbit around the Sun, larger than a meteoroid but smaller than a planet. Most asteroids can be found in a belt between the orbits of Mars and Jupiter.
