A 2000-foot-asteroid will fly past Earth Wednesday night at the closest distance it has come in the past 400 years, according to NASA. The asteroid, known as 2014 JO25, will pass at a distance of 1.1 million miles — about 4.6 times the distance from Earth to moon — and will be its closest approach for at least the next 500 years.
How to see it: The asteroid will approach Earth from the direction of the sun, and will become visible for one or two nights after April 19.
Don't freak out: NASA said there is no chance the asteroid will collide with Earth.
