What force allows asteroids to fall from orbit and hit Earth's surface?
The asteroids that strike earth's surface do not fall from orbit. Asteroids have fairly small masses, so their orbits are easily altered by interactions with other objects. Sometimes the orbit of an asteroid is changed such that its orbit intersects Earth's orbit. If the timing works out so that the asteroid reaches the point of interestion at the same time as Earth does, then a collision will result.
How did rings form on Saturn?
THe Saturn Rings are a "Belt" of asteroids that have all found a similar orbit around Saturn. They are made after a collection of asteroids fall into the same orbit, and when observed from a distance, look like the classic "rings".
What is the eccentricity of asteroids?
it is how circular and asteroids orbit path is.
Do comets orbit asteroids?
No. Comets orbit the sun.
What planets do asteroids fall on?
Asteroids can fall on any planet (or moon).
What are the names of the asteroids that cross Earth's orbit and Jupiter's orbit?
Main Belt asteroids -- a band of asteroids located in the "missing planet" gap between Mars and Jupiter. None of these are economically attractive in a near term program because they are too far from Earth.Amor asteroids -- asteroids whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit (i.e., "outside-t" Earth orbit). Many have orbits which reside entirely between Earth and Mars. Some of these are economically attractive in the near term.Apollo asteroids -- asteroids whose orbits cross Earth's orbit. Apollo asteroids spend most of their time outside Earth orbit. Many of these are economically attractive in the near term.Aten asteroids -- asteroids whose orbits cross Earth's orbit. Unlike Apollos, Atens spend most of their time inside Earth orbit. A large percentage of known Atens are economically attractive in the near term.
Does a asteroid orbit the sun?
Yes. Asteroids orbit the sun.
The location of the asteroids in relation to the planets?
Asteroids wander near and far, the majority however lie in an orbit between Mars and Jupiter simply called the asteroid belt. They get bumped out of orbit when they hit each other and generally fall towards the sun pulled by it's gravity.
Do asteroids have a elliptical orbit?
No, comets do.
Why are asteroids safe in circular orbits but insafe in elleptical ones?
Asteroids are safer in a circular orbit than an elliptical orbit because being in an elliptical orbit causes them to tumble in an erratic manner. Larger asteroids are sometimes referred to as planetoids.
Do most asteroids orbit in the same direction as planets?
Yes asteroids orbit the sun counter-clockwise, just like all the planets
Where is a asteroid locates at?
The asteroids are located between the orbit of Mars and the Jupiter. The asteroids are believed to be the remain of a planet that once used to orbit the sun.
