“The asteroid will pass some 4.6 million miles away from Earth, which is about 10 times the distance between the Moon and Earth, so there’s no risk to talk about,” Shustov told RIA Novosti.
What makes it special isn’t its larger-than-usual size (equal to three football pitches), but its unique 1.82-year orbit around the Sun. Nereus approaches Earth at a safe distance roughly every 10 years because of this.
According to the scientists, the asteroid’s regular passing makes it a perfect candidate for a future robotic mission, and even a mining operation – it is believed to be rich in nickel, iron, and cobalt.
Despite currently posing no threat, Nereus is closely monitored by space agencies to make sure it does not deviate from its path.
As part of the work to protect the planet from a catastrophic encounter with a large space object, NASA last week launched a mission called the Double Asteroid Redirection Test (DART). The mission will attempt to ram two asteroids into each other in order to change their course, with the actual impact scheduled for next September.
