What else can I help you with?
All meteorites collected on Earth come from asteroids or comets?
Most meteorites come from asteroids, which are rocky bodies orbiting the sun. Some meteorites could also come from comets, which are icy bodies. Both asteroids and comets can collide with Earth, resulting in meteorites.
What is true about asteroids?
Asteroids are small rocky bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter. They vary in size, shape, and composition, and some have the potential to collide with Earth. NASA and other space agencies study asteroids to understand their origins and potential impact hazards.
Why has interest in near-earth asteroids increased in recent years?
Interest in near-Earth asteroids has increased in recent years due to the potential threat they pose to Earth if they were to collide, as evidenced by past impact events. Additionally, advancements in space technology have made it more feasible to study, track, and possibly deflect these asteroids to mitigate the risk of a catastrophic impact. This has led to increased funding and missions aimed at studying and monitoring near-Earth asteroids.
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).
Does only the earth rotate on its axis?
No, all the planets, moons, asteroids and the sun do.
Are asteroids near earth?
Numerous asteroids are in constant motion around the earth, infinitely tracing their orbits. Occasionally some will collide or break down and fall as bits of meteor to Earth.
How does path of the asteroid compare to the path the earth travels?
It doesn't. In an estimated 23 years, a belt of asteroids will collide with the earth.
How does the earth get impact by the asteroids?
When the two orbits intersect, they will collide. Most asteroids are in orbit around the Sun, as the Earth is. They seldom cross paths, making an impact pretty rare. Most asteroids are large enough to easily make it through the Earth's atmosphere.
Why do astronomers search for near earth asteroids?
Near-Earth asteroids have some potential to collide with Earth. The effects of an impact, even from a relatively small asteroid, could be devastating. So, scientists are working to find objects that might collide with Earth. If one is shown to be a substantial danger, then strategies for deflecting it to miss earth may be discussed.
Are shooting stars asteroids?
Sometimes. We call them "asteroids" when we see them floating in space. Occasionally, one of them (or a piece of one) will collide with the Earth's atmosphere, and it will burn up as a meteor.

Does space junk interact with asteroids?
This would happen, space junk could collide with asteroids, but most space junk is close to the earth, away from the main asteroid belt. It would be more likely to collide with meteroids and other bits of space junk.

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.
Does only the earth rotate on its axis?
No, all the planets, moons, asteroids and the sun do.
