NASA expects the asteroid called OD 2019 to review our native planet on the so-called trajectory of Earth's Closed Approach. The asteroid will arrive tomorrow afternoon (Wednesday, July 24), less than three weeks after being spotted on July 5th. NASA's asteroid trackers estimate that the space rock will close on Earth around 23.30 in the morning. When this happens, the giant asteroid will come nearer to the moon.
Asteroid 2019 OD is an Earth object of the Apollo or NEO type.
All NEOs are asteroids and comets that run around the Sun within boundaries. from the asteroid belt between Mars and Jupiter.
NASA said: "Earth objects (NEO) are comets and asteroids that have been driven by the gravitational attraction of nearby planets into orbits that allow them to enter the earthly neighborhood. 1

Even more rarely, NEOs will unexpectedly hit the Earth like the Chelyabinski meteor exploded over Russia in 2013
Space rock masses in was only measured at a distance of about 65 feet (20 meters), but the power of the eruption blew out the windows over a wide radius, injuring more than 1,000 people with pieces of glass
In this case, Asteroid OD was calculated to measure somewhere in the range from the 170.6ft to 393.7ft (52m to 120m) in diameter.

At the top of this estimate, the asteroid stands on high above the Big Ben Clock Tower in London, and the Statue of Liberty in New York, USA. Most of the rocky asteroids formed in the warmer solar system
So how far NASA expects the asteroid to fly and if there is any real danger of the rock?
Tomorrow afternoon, the asteroid will catch up at a tremendous speed of about 19.17 km / h or nearly 43,000 km / h
The same scale will approach the Earth at a distance equivalent to 0.92 lunar distances (LD) , where a distance to the moon measured the distance to  READ MORE: Watch a Big Asteroid DESTROY Earth in Simulating a Fire Crash

This means that the asteroid will safely overtake Earth
In other words, the asteroid will approach the planet by 0.00236 astronomical units (AU).
One AU represents the distance from Earth to the Sun or about 93 million.
After the next flight, the asteroid will briefly approach the moon, but then NASA does not expect us to visit our corner of space again.
Quick facts about asteroids and comets:
1. According to NASA, an asteroid with a football field size faces our planet once every 2000 years.
2. Asteroid with car size reaches the Earth on average at least once a year
3. Some of the larger rocks in the space of the asteroid belt can be larger than 583 miles.
4. When the ice comets fly around the Solar System, their outer layers sublime in the sun's heat and leave behind a luminous path. Meteor, which survives the fiery descent through the earth's atmosphere, is known as a meteorite.
