earthnear

earthnear is a concept or term that refers to objects in space that are in close proximity to Earth. This can encompass a wide range of celestial bodies, including asteroids, comets, and even certain satellites. The definition of "near" is relative and can depend on the context, but generally it implies an object whose orbit brings it within a certain distance of our planet, often within a few million kilometers.

Astronomers actively track Near-Earth Objects (NEOs) due to their potential significance. Some NEOs are studied for their scientific value, offering insights into the early solar system. Others are monitored for potential impact risks. While the probability of a catastrophic impact event in the near future is very low, the scientific community takes the possibility seriously and invests in detection and tracking programs.

The study of earthnear objects involves sophisticated telescopes and observational techniques. These efforts aim to discover as many NEOs as possible, determine their orbits with high precision, and assess their physical characteristics. Understanding the population and behavior of these celestial bodies is crucial for both scientific advancement and planetary defense.
