NASA expects the asteroid to miss our homeworld just before 2pm GMT on Friday, March 21st. The asteroid will ground the Earth on a NASA's "Close Earth Approach." If that's the case, NASA's asteroid trackers believe that space rock is at a whopping speed of 5.37 km per second, or 12,012, According to NASA asteroid experts from the California-based Jet Propulsion Laboratory (JPL), the asteroid was first encountered this year on March 9.
The NASA's JPL has since made 135 observations, to determine the size, velocity and trajectory of the asteroid.
The space rock was called asteroid 2019 EA2 and was classified as near-earth object or neo-type Aten type.
NEOs are all comets and asteroids that are on
Occasionally, asteroids like EA2 come dangerously close to the planet, but do not always strike the earth.

Tonight, the space rock will drop the Earth from an estimated point close to the distance of so-called 0.80 lunar (LD) distances.
This is a distance of about 306.675 km or 80 percent of the average distance of the Moon from Earth.
NASA also estimates that the EA2 is somewhere in the lunar country. Area o The diameter of an asteroid is comparable to five London double-decker buses lined up in a row.

Astronomer Eddie Irizarry of the Astronomical Society of the Caribbean tells EarthSky.org that the space rock is about the size of a house.
an estimated size of 82 feet (25 m) in diameter, meaning that it is slightly larger than the asteroid that penetrated into the atmosphere over the sky of Chelyabinsk (Russia) on February 15, 2013.
"This asteroid – estimated to be 55 feet (17 m) in diameter – caused a shockwave that shattered windows in six Russian cities and sought medical help for some 1,500 people.
"2019 EA2 is a space rock of the type Aten or Erdkreuzung. Its orbit brings it between the orbits of the planets Venus and Earth.

"This will be the closest approach to this particular asteroid for the next 112 years since the next encounter with our planet will take place in March 2131. "
NEOs like EA2 often traverse Earth's orbit while orbiting hundreds and thousands of planets, year after year.
According to NASA, EA2's next approach will be February 8 and August 1, 2022.
On July 16, 2039, the asteroid will also float past the planet Venus.
