Get out your telescope, a massive asteroid will be passing by Earth on Friday, as close as it will get for the next two centuries.
The asteroid, known as QE2, is 1.7 miles across—nine cruise ships in length—and has its own moon. But rest easy: it will be passing at a comfortable distance of 3.6 million miles, so there’s no chance of collision.
With a telescope of at least four to six inches in mirror size, you should be able to view it from now through the first week of June, in the southern skies. If you want the best view, Space.com will be hosting a livestream of the asteroid’s passage at 4:30 EST tonight.
