Asteroids are generally bigger than comets, with sizes ranging from a few meters to hundreds of kilometers in diameter. Comets are typically smaller and are made up of rock, dust, and ice. However, there can be exceptions, and sizes can vary among individual asteroids and comets.
An asteroid is basically a rock in space. A meteor is basically a space rock falling into our atmosphere. Therefore, meteors are asteroids that are falling into our atmosphere, there is no size comparison, only a location and action change.
Comets do not fall. They orbit around the Sun in elongated orbits, with their paths often bringing them close to the Sun before they swing back out into the farther reaches of the solar system. This motion is due to the gravitational forces acting on the comet from the Sun.
No. The meteors you see in meteor showers are sand to pebble sized objects that burn up long before reaching the ground. Most meteors are too small to reach the surface. Meteorites come from larger meteors that fall individually and often show up brilliantly in the night sky. Some a bright enough to be visible during the day.
The number one thing in our solar system is space, or empty vacuum, through which blows the solar wind. The sun is the next largest thing in the solar system, outmassing all the planets, asteroids, comets, and icy debris beyond the orbit of Neptune by a factor of a thousand.Planets, their moons, the Kuiper Belt, Oort Cloud, comets, asteroids, and meteroids constitute much of the remainder of the solar system.Our solar system consists primarily of the sun, which accounts for 99% of the solar system's total mass. The remaining 1% are the eight major planets and their moons, numerous minor planets, and other bodies such as comets and asteroids.
I think they're simply called asteroids if that's what you're asking. You may be thinking of meteors though. Meteors when they're in space. Meteorites when they fall to Earth.

Comets, while visible in the sky, do not normally fall to Earth. Meteors do fall towards Earth very quickly.

Asteroids, meteoroids, and comets are space objects that are made of chunks of rock. Asteroids are rocky bodies that orbit the Sun within the asteroid belt, meteoroids are smaller rocky fragments that travel through space, and comets are a mixture of rock, dust, ice, and frozen gases.
Yes, meteors do fall very quickly to Earth.
Asteroids can fall on any planet (or moon).
The materials they are made of and what happens to them in relation to the Earth. Meteors are small chunks of rock and metals that fall into Earth's gravity field and pass through the atmosphere, burning up in most cases. An asteroid is a celestial body smaller than a moon and it may be rock or minerals and often is found in a group - a field of asteroids. They are now often called "minor Planets." A comet is a semi-frozen asteroid that orbits the Sun and when close to the Sun shows a 'tail' - this is debris coming off the comet including ice, dust and small rocks. It is guessed that some asteroids were actually comets that had their coverings burnt off over time.
They do fall on the Earth.
