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.
What asteroid group does eros belong to?
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.
Do any asteroids have orbits that come near the earth?
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.
What are facts about Apollo asteroids?
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.

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.
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.
What was the mission of the near spacecraft?
The NEAR spacecraft, short for Near Earth Asteroid Rendezvous, was designed to study and explore asteroids. Its primary mission was to orbit and study the near-Earth asteroid 433 Eros to understand its composition, structure, and history. It provided valuable insights into the nature of asteroids and their potential impact on Earth.
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.
Are asteroid near misses always small asteroids?
No, asteroid near misses can vary in size. Some near misses involve small asteroids that burn up in the atmosphere, while others may involve larger asteroids that pass by Earth at a safe distance. It is important for scientists to monitor and track all potentially hazardous asteroids to assess their risk.
