NASA Asteroid WARNING: Rock Found LAST WEEK will skim the earth as close as the Moon today | Science | News



The impressive asteroid, called by NASA Asteroid 2019 CN2, will make a so-called "Earth Close Approach" today. NASA astronomers have narrowed the passage down to just before midnight. 11 GMT (UTC), with an uncertainty of about four minutes. As it swings past, the NASA Jet Propulsion Laboratory (JPL) in California, the Asteroid CN2 estimates almost to miss the earth from a distance similar to that between the Earth and the Moon. The incredibly dense flyby comes exactly one week after the JPL first spotted the bricks on its radars.

According to NASA's research center, Asteroid CN2 was first observed Monday, February 4, 2019.

NASA has since calculated the orbit of the space rock to determine that CN2 has been approaching Earth since at least October 1901.

This is because the asteroid is a so-called "near-ground object" – an asteroid or the comet of a circulatory path that closely crosses it from the Earth.

NASA explained: "Near Earth objects (NEOs) are comets and asteroids that have been overthrown by the gravitational attraction of nearby orbiting planets that allow them to enter the Earth's neighborhood.

"Consisted mainly of water ice with embedded dust particles, comets originally formed in the cold outer planetary system, while most of the rocky asteroids formed in the warmer inner solar system between Mars and Jupiter circuits."

Today, the Asteroid CN2 is expected to make its closest approach to our home world since its first known air city of Earth.

Nearly, JPL estimates that CN2 comes to earth from a distance of 0.00377 astronomical units (au).

An astronomical unit approaches the average distance between the earth and the sun – about 93 million kilometers (149.6 million km).

The Asteroid CN2 will significantly reduce this to only 350,443 miles (536,984 km).

This corresponds to 1.47 Lunar Distances (LD) or 1.47 times the distance from the ground to the moon.

Fortunately, there is nothing to fear from the asteroid passage because it is not going to hit the ground.

But the space path is big enough for the researchers to be aware of their path.

NASA's calculations show CN2 targets somewhere in the range of 20.3 to 45.9ft (6.3m to 14m) in diameter.

At the upper end of the bay, the space rock is a little longer than a double-decker bus in London.

The asteroid is also estimated to be about seven times as long as a Queen Size Bed and 3.4 times longer than a Volkswagen Beetle.

After the asteroid leaves the corner of the Earth later in the day, CN2 will make a close approach to the moon around noon. 6.46 GMT today.

The Asteroid CN2 will then visit the earth again on October 23 in 2024 and July 1 in 2025.
