Quick call Bruce Willis!
The asteroid 2014 DX110 will pass between the Earth and the Moon, at a distance of around 217,000 miles from the Earth. It will be traveling at a speed of around 33,000 miles an hour. Don't worry though, the odds of it actually hitting the Earth are 1 in 10,000,000.
It will be at it's closest distance around 5:07pm.
At 4pm today, you can watch the feed from Slooh telescope.
