NASA is currently tracking on route to enter Earth's orbit, and it's estimated to be worth more than $5 billion.
The asteroid is dubbed "potentially dangerous," as is any space rock or comet that comes within the 4.65 million miles of Earth. The asteroid is dubbed 4660 Nereus, and while it is categorized as a "potentially hazardous" object, it will safely pass by Earth. The asteroid has a diameter of 1,085 feet and will break into Earth's orbit at a speed of 14,700 mph on Saturday, December 11, marking the closest the asteroid has come to Earth within 20 years.
When 4660 Nereus passes by Earth, it will be at a distance of 2.4 million miles, which is around 10 times the distance between the Earth and the Moon (238,855 miles). While 2.4 million miles sounds like an enormous distance when speaking in astronomical terms, it's quite small. According to the Asterank database that is currently tracking more than 60,000 asteroids, 4660 Nereus is estimated to contain $4.71 billion worth of nickel, iron, and cobalt.
