Asteroids

The satellite, or moon, called "Luna" averages 238,800 miles distant from Earth.

From the sun it goes Mercury, Venus, Earth, Mars, ASTEROID belt, Jupiter, Saturn, Uranus, Neptune, Pluto (although no longer classed as a planet). So the earth is inside the orbit of the asteroid belt.

No. An asteroid can be anything from 10 metres to 487km as in the case of Ceres the largest asteroid.

In Japan, the superstitions that are related to comet and asteroid is that it is death calling. People therefore are usually afraid to see the comets and asteroids.

size doesn't matter its the angle and speed of the asteroid that it is at, plus if that did happen the earth would either drift off into space and eventually get back into a orbit because of the suns gravity or explodes and everything would just flip, roll over, fall how ever you wanna put it. plus its nearly impossible for a asteroid to do that it would probably do what i said in the second sentence.

asteroid belt and kipter belt.

Mars and Jupiter.

Mercury is not a part of the asteroid belt. The asteroid belt is located between the orbits of Mars and Jupiter. Mercury is far closer to the sun.

Comets are fairly small bodies of rock and ice which are in a highly eccentric orbit around the sun. The actual nucleus of a comet can be between a few hundred metres across, to 40 or more km in diameter. Their mass is quite low, but their density is also quite low as they are mostly made of water ice and frozen gases.

They spend most of their time slowly orbiting the sun, far out beyond the outer planets (and way beyond the asteroid belt). Their orbit eventually brings them close to the sun, where the surface is heated and gives the comet its tails.

Just about any object in space will rotate - not just asteroids.

This asteroid does exist, found in less than two weeks before the Spanish La Sagra Observatory astronomer, 2012 DA14 just temporary number. Has been found to connect 10 days of observation, astronomers generally determined its orbit, similar to the Earth's orbit, but the inclination is large. Therefore, most of the time, the asteroid away from Earth came away. But it does have two opportunities each year the asteroid can run very close to the distance of the Earth.

Just said, year 2 chances will run to the near Earth asteroid. Last February 16 this year, when it was closest to the earth about 250 million kilometers, equivalent to the Earth-Moon distance of 6 times, partial, or very far. However, next year's February 15, 2012 DA14l indeed close to the Earth. It grazed from about 21,000 kilometers from the Earth's surface, the height of the geostationary orbit communications satellites used to broadcast television signals are low than us!

Though this is really close to the Earth rub in the past, but still just "rub." In the past it does not hit the Earth. 21000 meters in astronomy scale is really close to the standards of everyday life, this distance is far enough. It is unlikely to hit the Earth in February 2012 DA14 next year.

Yes. We have had several on record and probably many more that were not recorded.

An asteroid or meteor that would cause climatic change, about 1 in 600,000 to 1 in 10,000,000.

Yes, asteroids orbit Sun, even meteors and comets. But generally, every pieces of asteroid doesn't have orbits, it has a zone. They bump each other until they form into a larger ones. If an asteroid got out of the zone it now move freely into space and crashes into a planet by gravity. Astronomers now detected a planet, or a dwarf planet, or still an asteroid itself, called Ceres

the asteriod bet

Life did not start after the dinosaurs were wiped out. Life on Earth started billions of years before that. The asteroid wiped out a large portion of life on earth, but not all of it. Some things survived.

They are bigger than some stars. Depends what planet and star you are comparing like earth to our star the sun...well obviously the sun is bigger but earth to a lets say a neutron star(im not sure) but I think earth would be bigger

No

of all the minor bodies of the solar system, the largest fragments of rock are called asteroids, so yeah.

Of course, we have the "dwarf planets" now. They would be the answer, if you call them minor bodies

Very funny you asked as a matter of fact, it does. One is referred to as polypious persistous.

Yes.

Very powerful volcanoes can blast millions of tons of dust and ash high into the stratosphere, where it reflects a substantial fraction of the Sun's light and heat back into space. These happen every couple of centuries, and the weather gets several degrees colder for a year or two. VERY large eruptions can darken the sky for decades, and may be the cause of some ice ages.

Asteroid impacts can have similar effects. For example, something big struck northern Canada about 15,000 years ago, and the resulting mini-ice age called the Younger Dryas probably caused most large animals in North America and Siberia to become extinct, including the mammoth and mastodon, and the saber-toothed tiger. It also killed off the American aboriginal humans known as the "Clovis People" who had inhabited North America before that time. The "Native Americans" were a later migration from Asia a few thousand years later.

Meteor. Meteorites are the ones that do hit Earth.
