An asteroid the size of a large building will grow to nearly 30,000 MPH today. Unfortunately, its closest impact is about 3.6 million miles before traveling through the air and back into space without giving us the sweet liberation of global destruction.
According to NASA, the 2013 MD8 (an object close to Earth – NEO) will fly over the Earth around 11:55. "Tuesday, February 19, 2019 at 12:55 pm EST (2019 Feb. 19 Feb. 17:55 UTC), near-Earth object (2013 MD8), of a size between 38 and 86 meters (126 to 282 feet) ), will pass the Earth at 15.1 lunar distances, traveling at 13.60 kilometers per second (30,418 miles at the time). "
3.6 million miles is a very long way from Earth's standards, but astronomically speaking, it's damn near. Unfortunately, not close enough though.
The asteroid, named 2013 MD8, is a good sized asteroid and we would have done well in the air if it hit us, but an asteroid should be at least a kilometer in diameter to cause death and destruction on a global scale.
Fortunately, asteroids are flying all the time on Earth. So it's only a matter of time before we can finally hit each other and put everyone out of their misery. Astronomers know more than 15,000 asteroids close to Earth today, but there are literally millions of unknown and uncatalogued rocks that can hit us.
The good news is that someday an asteroid will hit Earth and destroy us all. The bad news is that this is not likely to happen in the next few weeks or even four years. But do not give up hope, asteroids are really hard to find, we discover them all the time and we could be directed to us much sooner than we think.
