You may have heard about the crazy meteor that shattered windows with its sonic boom this morning. Well, an asteroid’s passing Earth now, and NASA is livestreaming its progress.

The asteroid, known as 2012 DA14, is set to fly very close to Earth — it will come within 17,200 miles of us today. Experts say that while the asteroid will not hit Earth, it’s one of the first asteroids this big to come this close to our planet. It is a full 150 feet wide, about the size of a football field, as NASA notes.

The asteroid is set to fly by at its closest at 2:24 p.m. Eastern time.

Its arrival, however, was overshadowed this morning when a meteor flew through Earth’s atmosphere, breaking the sound barrier and causing a lot of commotion in the Russian city of Chelyabinsk. It created a massive sonic boom that sent glass from windows flying and set off car alarms. Reuters is reporting that more than 500 people sought medical help due to the glass.

The two space rocks, however, seem to be unconnected. As Slate notes, DA14 is coming from south to north, where the Russian meteor came from another direction, many hours before DA14 is expected to hit.
