Chapter 1: Overview of Asteroid 4660 Nereus
On Saturday, December 11, an asteroid known as 4660 Nereus will come near Earth's orbit. This event presents an intriguing opportunity for astronomers and space enthusiasts alike.

As it approaches, 4660 Nereus will reach a distance of approximately 3.86 million kilometers (about 2.4 million miles) from Earth—roughly ten times farther than the Moon's orbit. While this distance might seem vast, in astronomical terms, it is considered quite close!
Named after a deity from Greek mythology, specifically a sea god and son of Gaia, Nereus is an elongated asteroid measuring 330 meters (nearly 1,100 feet) in length. To put this in perspective, it is taller than the Eiffel Tower but shorter than the Empire State Building. During its closest encounter with Earth, Nereus will be traveling at an impressive speed of 23,700 kilometers per hour (14,700 miles per hour)—a pace 25 times greater than that of a Boeing 777 under optimal conditions.
Section 1.1: The Classification of Potentially Hazardous Objects
Any rapidly moving object that approaches within 7.5 million kilometers (4.65 million miles) is categorized as a potentially hazardous object, and 4660 Nereus certainly qualifies. Astronomers monitor these celestial bodies carefully, remaining vigilant for any changes that could pose a risk.
Although there is no immediate threat associated with 4660 Nereus, studying such asteroids offers valuable insights into the early solar system and can enhance our understanding of terrestrial planets like Earth. These investigations also contribute to our preparedness should a future asteroid be identified on a collision course with our planet.
