NASA expects the asteroid, called Asteroid 2019 BB5, to dash past the Earth on a so-called "Earth Close Approach". The airline's Jet Propulsion Laboratory (JPL) has narrowed the airfield down to noon. 10.18 GMT (UTC) Thursday 8 February. Shock asteroid news comes less than a week after JPL astronomers first observed the space bars against the ground. NASA first observed Asteroid BB5 on the night of January 30, and last track it on Monday, February 4.
Tomorrow the asteroid will swing past the planet at breakneck speeds of more than 14.270mph or 6.38km per second. Second.
As this happens, the asteroid reaches its closest possible distance to the ground.
But there is nothing to worry about because the Asteroid BB5 itself approaches our nearest planet by about 2.6 million miles (4.25 million km).
Near Earth objects (NEOs) like BB5 often dash past Earth on their journey around the Sun, but rarely do they hit our world.

NASA explained: "When they surround the sun, objects near the earth can sometimes approach Earth.
"Note that a" close "passage astronomically can be very far away in human terms: millions or even tens of thousands of kilometers."
According to JPL, Asteroid BB5 measures somewhere in the range from 39ft to 91.8ft (12m to 28m).
In other words, the asteroid could be up to 14 times longer than a Queen Size bed seven times as long as a Volkswagen Beetle car.

If the asteroid proves to fall somewhere in the lower end of the estimate, the asteroid is still about. 1.4 times the length of a double-decker bus in London.
Asteroids of this size are some of the most populous in the entire solar system and are also some of the most unpredictable.
There are currently some 791,515 known asteroids and 3,562 known comets lurk in the depth of the room.
NASA said, "With increasing regularity, scientists discover asteroids and comets with unusual trajectories, those that take them close to Earth and the Sun.

"Very few of these bodies are potential hazards to the Earth, but the more we know and understand about them, the better prepared we are to take appropriate action if you're on the move.
"Knowing the size, shape, mass, composition and structure of these objects will help determine the best way to divert a space rock that turned out to be on a ground-breaking path."
Asteroid BB5 will surely swing by Earth tomorrow, but it won't be the last thing we hear from space rock.
Based on NASA's circuit calculations, BB5 will swing at Venus in July 2021 and resume Earth in November 2021.
Then NASA expects repeatedly close approaches until at least December 2182.
