A huge 1km-wide asteroid is hurtling towards Earth, prompting astronomers to label it “potentially hazardous”. But don’t pack for Mars just yet – the giant space rock, ‘2014 JO25’, is expected to pass by our planet safely. According to NASA the encounter on April 19 will be the closest the asteroid comes to Earth in 400 years, and no projected future encounters will be as close for at least another 480 years.
However, another fly-by is expected in 2091 and the space rock also makes regular close approaches to Mercury and Venus. An asteroid of this size won’t have as close an encounter with Earth for more than 10 years. “The next known flyby by an object with a comparable or larger diameter will occur when 800-meter-diameter asteroid ‘1999 AN10’ approaches within one lunar distance in August 2027,” NASA said.
