The asteroid, called the 2019 RX2, is just one of many so-called "Near Earth Objects" or NEOs that are dangerously approaching our planet. In total, NASA estimates there are 796,901 known asteroids and 3,586 known comets in the solar system. The asteroid flew today (Thursday, September 12) in a "Close Earth Approach" trajectory that brought it closer to the planet. The flyby came just six days after NASA noticed the asteroid's orbit on September 6.
NASA said the rock would approach us at around 4.19am BST (3.19am UTC) today.
Asteroid 2019 RX2 is a type of Apollo rock orbiting the Sun within the inner circles of the solar system.
The asteroid follows a trajectory similar to the Asteroid 1862 Apollo and does not fly far outside the Earth's orbit.
Occasionally, NEOs like the RX2 will cross paths with Earth at different points in time.
According to NASA's calculations, the asteroid had approached Earth six times prior to this year's preliminary observations.

The first flyby took place 100 years ago on December 9, 1919.
After a close-up approach today, the space station appears at the corner of the Earth's space . again in 2024 and 2063.
NASA estimates that the Asteroid RX2 measures somewhere in the range 18ft to 39ft (5.6m to 12m) wide.
Typically, Earth-like cars strike once a year.
Fortunately, the small asteroid was enough to safely fire the sky without harming the earth.
Anything bigger and space rock could cause serious damage like a rock that exploded in Russia's Chelyabinsk Oblast in 2013.

The so-called Chelyabinsk Meteor measured only about 65.6ft (20m) in total but gunfire struck windows and injured more than 1,000 people with shards of glasses.
The good news is, N ASA does not expect Asteroid RX2 to harm the planet today.
The asteroid approaches our planet at speeds of around 5.34km per second or 11,945mph (19,224kph).
At its closest, the rock was flying from a distance of 0.01848 astronomical units.

A single astronomical flight of 93 million miles (149.6 million km), the distance from the Sun to on Earth.
This means that rock has not been taken to our planet for around 1.7 million miles (2.7 million km) – about seven times the distance to the Moon.
NASA states: "As they orbit the Sun, Near- The Object of the Earth may occasionally approach Earth.
" Note that a & # 39; close & # 39; that astronomical passage can be very far in human terms: millions or even millions of kilometers. "
