Asteroids

They are all less than a kilometer in diameter.

They both revolve around the sun and they are both smaller than planets or moon.

The two other large asteroids in our solar system are Vesta and Pallas. Vesta is the second most massive asteroid and is located in the asteroid belt, while Pallas is the third most massive and is also part of the asteroid belt between Mars and Jupiter.

well they do land in the planets but they dont HIT like PUNCH PUNCH PUNCH THERE NO they LAND ON THE PLANETS:)

Yes, meteoroids are basically small pieces space debris that are considerably smaller than asteroids. They're so small that many of them simply burn up in the atmosphere before ever reaching the surface.

An asteroid is a small rocky object that orbits the sun, primarily found in the asteroid belt between Mars and Jupiter. A planet is a larger celestial body that orbits the sun and has cleared its orbit of other debris. Planets are typically much larger and more spherical in shape compared to asteroids.

Several thousands. Most of them are the size of a grain of rice or smaller. A few each day may be the size of a baseball or occasionally the size of a basketball.

Once a week or so, the Earth is hit by a rock the size of a car, and once every few months, we get hit by something the size of a house. A couple of months ago, a meteor the size of a house exploded over central Indonesia; it scared a lot of folks, but apparently did no damage.

The VAST majority of these burn up completely in the atmosphere, surviving as nothing but dust. A few do make it to the Earth, often in small (fist-sized) chunks. Very few do any damage. Only a few people are known to have been hit by a meteorite; there was a boy in Germany last year who was struck in the hand by a meteorite the size of a pea.

Every few hundred years, bigger things hit the Earth, and some do a lot of damage. In 1908, a meteor or small comet exploded high in the atmosphere near a place called Tunguska, Siberia, causing an explosion the size of a nuclear bomb. 5000 years ago, a meteor struck in the Indian Ocean causing a tsunami, which may be the source of the "Great Flood" legends in Gilgamesh and Noah's Ark. 14000 years ago, something hit northern Canada causing the "Younger Dryas" mini-ice age.

It's called a "meteoroid" when it is out in space. When it enters the Earth's atmosphere and is heated to incandescence, the bright streak of light is called a "meteor".

If the object survives the fiery passage through the atmosphere and hits the ground, it is called a "meteorite".

(considering it was a huge asteroid) The world would be blackened out in some areas from the dust, there would be huge tsunamis ( if it hits the ocean)and earthquakes, and many volcanoes may erupt. plus millions of people would die.

Yes. There are some asteroids that are hundreds of kilometers in diameter.

Comets are Comets and Asteroids are Asteroids

The Chicxulub impact crater in the Gulf of Mexico is the most likely suspect for the meteorite impact that caused the Mesozoic extinction. The crater is 180 km in diameter, suggesting that the impacting body was approximately 10 km in diameter.

The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.

Comets and asteroids are superstitiously seen as bad sign in most cultures all around the world due to the fact that they have been linked to natural disasters in history. Halley's Comet, for instance, is seen as a bad omen.

Scientists may not have named all of the asteroids in the asteroid belt because there are so many that they are hard to keep track of.

The classic black and white game Asteroids was released by Atari in 1979

they go throughout the solar system.

The entire atmosphere will burn up small asteroids (meteors), but larger ones will strike the Earth. This is how the Caribbean Sea was created.

Because they do not have volatiles in them to form a coma as to comets.

planetoids.

As of October 2009 around 450,000 asteroids have had at least two days observation, with approx. 397,000 with calculated orbits, and around 222,000 with complete orbits.

it is a big ring of asteroids that separate 4 planets away from the rest!

Small asteroids are called meteoroids.

Yes. The asteroid belt - is a region of space that lies between the orbits of Mars and Jupiter. It's believed the region used to be an early planet - which was struck by something large enough to fragment the planet into billions of pieces - ranging in size from a grain of sand - to a small island.

The smaller version of an asteroid is known as a "meteoroid." Meteoroids are typically defined as small rocky or metallic bodies in space, ranging in size from a grain of dust to about a meter across. When meteoroids enter the Earth's atmosphere and produce a bright streak of light, they are called meteors, and if they survive the descent and land on Earth, they are referred to as meteorites.

The asteroid belt is part of the Solar System, if that's what you mean.
