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.

What is a near-earth asteroids?
according to statistics maintained by NASA's Center for Near Earth Object Studies (CNEOS), 17,759 NEOs have been discovered: 107 near-Earth comets and 17,652 near-Earth asteroids.
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.
Do any asteroids have orbits that come near the earth?
yes
What asteroid group does eros belong to?
The Near Earth Asteroids.
Why has interest in near-earth asteroids increased in recent years?
yes
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.
Celesitial neighbors of earth?
Moon Near-Earth Objects (asteroids, comets) Venus Mars
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 near- earth asteroids a danger?
If they crash into Earth, an enormous amount of energy can be released, since they move very fast.
Should the US keep searching for Near Earth Objects?
Yes because large asteroids heading for earth are Near Earth Objects and if they were to hit many people can lose their lives.
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.
