The universe never lets us here on Earth go very long before reminding us that we’re really just a random dice roll away from global catastrophe. The next timely reminder will happen on April 19th when asteroid 2014 JO25 will cruise by our planet at a relatively safe distance of roughly 1.1 million miles. That distance, while relatively comfortable, is still pretty close, especially when you realize how large the rock actually is.

NASA’s Jet Propulsion Laboratory describes 2014 JO25 as being approximately 2,000 feet wide, or about 650 meters across, which is a little more than two-fifths of a mile. That’s a pretty large chunk of rock, and NASA says it’s the largest asteroid to come that close to Earth since 2004, with the next similar flyby predicted to occur in 2027 when asteroid 1999 AN10, measured at about a half mile in width, makes an appearance at a distance of 236,000 miles.
