The asteroid, called 2019 RX2, is just one of many so-called near-Earth objects or NEOs that approach our planet dangerously. Altogether, there are 796,901 known asteroids and 3,586 known comets in the solar system, according to NASA estimates. The asteroid flew today (Thursday, September 12) on a trajectory "Close Earth Approach," which brought him very close to the planet. The flyby was only six days after NASA first observed the orbit of the asteroid on September 6.
NASA said the rock will approach us today at 4:19 am CET (3:19 pm UTC).
The asteroid 2019 RX2 is an Apollo rock type space orbiting the Sun in the inner circles of the solar system.
The asteroid follows a trajectory similar to the asteroid 1
Occasionally NEOs like RX2 cross Earth at different times.
According to NASA calculations, the Earth's asteroid has already approached six times before it was first observed this year.

The first flyby took place 100 years ago on December 9, 1919.
After today's approach, space rock will reappear in the earth's corner of space in 2024 and 2063. [NASAestimatesthattheAsteroidRX2hasadiameterrangingfrom18feetto39feet(56metersto12meters)
On average, such car-sized rocks hit Earth once a year.
Fortunately, the asteroid is small enough to safely burn in the atmosphere without hitting the ground.
Every major and space rock could cause serious damage, like the rock that exploded in 2013 over the Chelyabinsk region of Russia.

The so-called Chelyabinsk meteor had a diameter of only 20 meters, but its explosion blew out windows and was injured more than 1,000 people with broken glass.
The good news is, N ASA did not expect today that the asteroid RX2 would hit the planet.
The asteroid approached our planet at a speed of about 5.34 km / s from 0.01848 astronomical units.

A single astronomical measurement corresponds to a distance of approximately 93 million miles (149.6 million km) The Sun to Earth.
This means that the rock missed our planet by about 2.7 million kilometers – about seven times as far as the moon.
NASA said, "As they orbit the Sun, Earth objects may occasionally approach Earth.
"Note that a 'narrow' passage can be astronomically very distant in human terms: millions or even tens of millions of kilometers."
