Next month, Earth will be paid a visit from an old cosmic friend: a two-mile-wide asteroid called (52768) 1998 OR2 that will come within about 4 million miles of our planet. This behemoth will be the largest asteroid to swoop in close to Earth’s orbit in 2020, zooming by at almost 20,000 miles per hour, according to Prabhjote Gill at Business Insider.

Known to researchers since July 1998, this massive space rock offers skygazers the chance to scope out an object that NASA has previously designated “potentially hazardous,” so named because they occasionally pass near Earth’s orbit and are large enough to cause serious damage on impact.
