SPACE — A whopper of a space rock is set to get up close and personal to Earth in the coming days. But fear not, it’s not on a collision course, so no asteroid apocalypse...yet. <br /> <br />A asteroid known as 2014 JO25 is roughly 650 meters across — that’s the height of the world’s second tallest building, or the length of six NFL football fields. <br /> <br />NASA reports that the massive rock will pass Earth at a safe distance of 1.8 million kilometers, or about 4.6 times the distance from the earth to the moon. <br /> <br />The asteroid will approach Earth from the direction of the sun, and is set to fly past on April 19. <br /> <br />With a surface twice as reflective as the moon, the asteroid will still be visible in the night sky for those using only small telescopes. <br /> <br />The rock will only be visible for one or two nights. It’s a rare opportunity for astronomers to study the massive specimen, which won’t be this close again for at least 500 years.
