Oval asteroidNamed 4660 Nereus, it is 1,082 feet (330 meters) long and will invade the Earth’s orbit at 14,700 mph (23,700 km / h) on Saturday, December 11. It will pass through the Earth at some distance without impact, but it will still be closer to us than it was 20 years ago.
Nereus is about 2.4 million miles (3.86 million kilometers) away from the Earth Month.. This may sound like a huge gap, but by cosmic standards it’s actually a stone throw.

NASA has flagged space objects within 120 million miles (193 million kilometers) of the Earth as “near-Earth objects” and “potentially” fast-moving objects within 4.65 million miles (7.5 million kilometers). Flag as “dangerous”. When flagged, astronomers carefully monitor objects and look for deviations from the predicted orbits that could put them on the course of collision with Earth.
The 1982 solar orbit of Nereus, first discovered in 1982, approaches the Earth almost every 10 years. Since Nereus frequently visits our region of the solar system, NASA and Japan Aerospace Exploration Agency once considered using JAXA’s Hayabusa spacecraft to collect samples from it, but eventually. Settled on another asteroid (Itokawa 25143).
NASA predicts that Nereus will make its next approach to Earth on March 2, 2031 and November 2050. It is predicted that Nereus will be even closer on February 14, 2060, when it can reach within about 740,000 miles (1.2 million km). Of earth.
Nereus is not only a potential robot craft target sent by NASA, but also a fascinating award for future space mining. AsterankA database that monitors over 600,000 asteroids estimates that asteroids have nickel, iron When cobalt A total of $ 4.71 billion worth of deposits.
If we find an asteroid heading straight, the space agency is working on a solution. On November 23, NASA launched a spacecraft as part of a double asteroid redirection test mission to redirect the asteroid by taking it off course and ramming it. Live science previously reported.. China is also in the early planning stages of an asteroid ramming attack. They propose that 23 of the Long March 5 rockets can be diverted from the asteroid by driving them into the asteroid Bennu. Potential catastrophic impact on the planet, LiveScience previously reported.
