A giant asteroid has already zipped by Earth once today, and it'll do it again later tonight.
The asteroid, officially named 2014 JO25 but nicknamed "The Rock," is 2,000 feet long, and will come within 1.1 million miles of Earth. It's not exactly threatening to hit the planet, but that's extremely close in space terms, AccuWeather meteorologist Brian Lada said.
The Rock will be visible (with a telescope) in the eastern sky at about 7 p.m. Eastern time, USA Today reports.

It's the closest an asteroid of this size has come to Earth since the 3.1-mile wide Toutatis in 2004, and we won't see another one this big until 2027, according to Sky and Telescope magazine.
