Based on Newtonian Laws of Motion, asteroids are still under the original velocity imparted to them when they were made. The only external influences are the gravitational pull of the sun and other celestial objects.

∙ 13y agoWell asteriods come at an amazing speed from some type of collision elsewhere, but anyways it comes very fast, hurdling past earth and then if its close enough and is not going too fast it will get caught in earths gravitational field and then it will either burn up in its atmosphere or crash into earth which could be then end of mankind although its very rare, but there have been countless impacts of smaller meteorites

All meteorites collected on Earth come from asteroids or comets?
False.
Has a rogue planet ever come near earth?
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
Why are scientists concerned about near-Earth asteroids?
Asteroids, even very large ones, actually come close to earth regularly and cause no harm and no effect on life on earth. The concern would be a large asteroid crashing into the earth.
Which of these hit the earth comets or asteroids?
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
How do you know asteroids have hit the earth?
The evidence that asteroids have collided with earth before, depends on the surface. The way you can find this if there is unusual shapes in the ground( e.g. really deep ditch, that is too big for a human too dig).
Do asteroids come close to the earth?
They can.
Do comets or asteroids come close to earth?
Yes
Can asteroids come in earths atmosphere?
Yes. Asteroids can enter earth's atmosphere. In such an event the asteroid will probably strike earth's surface.
Do any asteroids have orbits that come near the earth?
yes
All meteorites collected on Earth come from asteroids or comets?
False.
How do comets come toward earth?
Comets come toward earth during their orbits. They are drawn toward the sun by gravity and sometimes cross earth's orbital path in the process.
Has a rogue planet ever come near earth?
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
Why are scientists concerned about near-Earth asteroids?
Asteroids, even very large ones, actually come close to earth regularly and cause no harm and no effect on life on earth. The concern would be a large asteroid crashing into the earth.
Why are some asteroid called neo's?
In dicussing asteroids, NEO stands for Near-Earth Object. NEOs are asteroids whose orbits come close to or cross Earth's. This creates a potential hazard for a collision.
What are the group of asteroids that may occasionally cross earth?
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
What are NEAs?
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
Are asteroids larger then earth?
asteroids vary in size from rock size to earth size and bigger.
