Two large asteroids—one of which could measure more than 1,000 feet across—are set to have a close encounter with Earth next week.

The first of the two space rocks to make a close approach is known as 2016 CZ31. According to figures from NASA's Center for Near Earth Object Studies (CNEOS) database, this object will come no closer than around 1.7 million miles to our planet at 11:02 p.m. UTC, or 7:02 p.m. ET, on Friday, July 29.
