How to calculate if an asteroid will hit the earth?
Asked by Wiki User
There is essentially no chance of any given asteroid ever hitting the Earth, because those with orbits that made them likely to hit the Earth have already hit the Earth. So it's not something you really need to worry about.
If you're just curious... well, really, you don't want to know that badly. It comes down to solving n-body gravitational equations, and for any reasonably sized n (i.e. larger than, say, 3) there is no known exact solution except in special cases, so you have to use numerical methods and hope the interesting bits don't get lost in rounding errors.
How fast can an asteroid go?
Asked by Wiki User
Asteroids orbit the sun at several tens of thousands of miles per hour. The speed varies depending on the orbit.

Asked by Wiki User
the gravity stops them from floating away

What year did the dinosaur's get killed by the asteroid that hit the earth?

65 million years ago.
What two planets is the asteroid belt in our solar system between?
Asked by Wiki User
The Asteroid Belt orbits between Mars and Jupiter, at about 3 AU. There are several objects not properly classified as asteroids orbiting within the belt, mainly the dwarf planet Ceres and the protoplanets Vesta and Pallas.
Are asteroids big?
Asked by Wiki User
They can be anything from 10 meters across to much, much larger objects, the largest is 940 Kilometers across.
What is the largest object in the asteroid belt?
Asked by Wiki User
The largest object in the asteroid belt is Ceres at about 580 miles across. It is classified as a dwarf planet rather than an asteroid.
What is the average distance between asteroids in the asteroid belt?
Asked by Wiki User
Unlike old science fiction movies which gives you the impression that asteroids are close together, the average distance between asteroids is approximately 1 million km. If you were to travel through the asteroid belt, the chance of encountering an asteroid is next to nothing.
How long is a year on vesta the asteroid?
Asked by Wiki User
The asteroid belt is a region about a hundred million miles across, so there's no such thing as "a year on the asteroid belt". Any given asteroid in the core region of the belt could have an orbital period from a little under 3 up to nearly 6 years.
1 Ceres, for example, has an orbital period of a bit under 1682 days (4.6 years).
What atmospheric gases on asteroid belt?
Asked by Wiki User
The asteroid belt does not have an atmosphere.
Where are most asteroids in our solar system found in space?
Asked by Wiki User
Asteroids are found all over the solar system. The vast majority is located in the asteroid belt between the orbits of Mars and Jupiter.
Have any asteroids hit the space station?
Asked by Wiki User
Huston, we haven't been hit by space objects. I repeat, we have not been hit by space objects, YEAH!
What are the differences between Pluto an a asteroid?
Asked by Wiki User
Pluto is technically an asteroid, but it's unusual in that it is ball-shaped. most asteroids are too small to form a ball shape.
How much does an asteroid weigh?
Asked by Wiki User
If it happens to be Midas-22, it's worth quite a chunk of change.
How long does it take for the asteroid belt to make a complete orbit around the sun?
Asked by Wiki User
This is not a scientific answer (corrections welcome) but based on the location of the Asteroid belt, the length of the Martian year and the length of the Jovian year, I would surmise that it takes the asteroid belt about 7earth years to orbit the sun. But don't quote me!
