If they crash into Earth, an enormous amount of energy can be released, since they move very fast.
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.
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.
Mainly to see if the asteroids are going to pose a collision danger with regards to the 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.
Eros belongs to the Amor asteroid group, which are a class of near-Earth asteroids that have orbits that bring them close to Earth's orbit. Amor asteroids are named after the asteroid 1221 Amor, which was discovered in 1932.
There are no known asteroids on a collision course with Earth in the near future. Astronomers constantly monitor space for any potential threats and would inform the public if there were any imminent danger.

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.
Apollo asteroids are a group of near-Earth asteroids with orbits that intersect with Earth's orbit. They are named after the first asteroid of this group discovered, 1862 Apollo. Some Apollo asteroids are classified as potentially hazardous asteroids due to their close approach to Earth.

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.
