There's a notable, near-ish-collision on Earth -- or at least one that's looming -- and the object that may be about to crash is traveling at 18,000 MPH!!!
NASA has sounded an alarm that a giant asteroid is about to pass Earth. It's somewhere between 318 and 720 feet in length ... about the size of the Taj Mahal and the Great Pyramid of Giza.
The thing's even got a name -- 2008 G020.
Well, when we say near-collision, it's all relative. It's supposed to come as close as 2.8 million miles to our planet. In NASA-ese ... it's labeled an Apolo, which is a "near-Earth" designation.
To give you more context ... the Moon is 238,855 miles from Earth, while Mars is 236.5 million miles away. So, somewhere in the middle.
This won't be our closest encounter with G020. In 1901 it got 1 million miles from Earth.
Shhhhsh ... close call, right?
