Asteroid swept within moon’s distance Monday nightAstronomers did know in advance that asteroid 2016 FW13 would pass closely – but safely – on April 5, 2016. Check out a photo from the Virtual Telescope Project.
On April 5, 2016, at 02:21 UTC), a 6-meter-large near-Earth asteroid labeled 2016 FW13 made an extremely close, but safe, sweep past the Earth. Astronomers knew in advance that the asteroid would come within 200,000 miles (320,000 km) of Earth – inside the moon’s orbit. Gianluca Masi at the Virtual Telescope Project sent this photo to EarthSky. He wrote on his website:
And it’s also good news for us earthlings who are depending on astronomers to locate asteroids, which, everyone now agrees, have the potential to be a threat to Earth. Astronomers do now have confidence they know the whereabouts of all the big ones, and that no large asteroid is headed our way anytime soon, but these little ones often elude us. The estimated size of asteroid 2016 FW13 (about 20 feet or 6 meters) is in contrast to the much-larger estimated size of the Chelyabinsk meteor that entered Earth’s atmosphere over Russia in February, 2013. Its shock wave broke windows in six Russian cities and caused some 1,500 people to seek medical treatment, mostly for injuries related to flying glass. The Chelyabinsk meteor was estimated at 65 feet (about 20 meters) wide. Astronomers didn’t see it in advance because it came from the direction of the sun.

Comment: So the one that hit Russia wasn't detected on time cuz it came from the direction of the sun?! What's to say an even bigger one won't come from that same direction!??? I feel so safe n cozy!
