The asteroid named by NASA 2019 SC was first observed in the Solar System on September 6 this year. As the discovery was made, NASA's asteroid trackers said the space rock was flying toward us along a trajectory of near approach. The asteroid approached Earth on September 19 at around 7.37 BST (6.37 UTC). The closest asteroid is scraped nearly as close as the moon.
Asteroid 2019 SC is a trajectory-type Apollo scale similar to Asteroid 1862 Apollo.
NASA also ranked Asteroid SC as a NEO or Middle Earth Object.
NEOs are all comets and asteroids that approach the Earth in their orbits of the internal solar system.
According to estimates by the European Space Agency (ESA), there are currently 20 756 known NEOs in the system. [1
Of these, 877 have listed it on ESA's NEO Risk List. Fortunately, Asteroid SC is
NASA calculates that rock measures range anywhere from 29.2 feet to 65.6 feet (8.9 m to 20 m) through
but the asteroid can still to strike if it enters the atmosphere unnoticed.

An incident like this happened in 2013 when 65.6 feet (20 m) wide entered in the sky above the Russian Chelyabinsk region.
The space rock exploded in mid-flight, blowing out windows in a wide radius and injuring more than 1,000 people with pieces of glass.
On Thursday, however, the asteroid missed our planet from a safe distance.
According to the NASA Near-Earth Object Research Center, the asteroid gave the Earth a wide space of about 0.00360 au.

Only one au measures the distance between our home planet and the sun – about 93 million miles (149.6 million km).
In other words, the Asteroid SC missed the Earth from a distance of 334 640 miles (538,552 km) or 1.4 times farther from the moon.
NASA says, "As they orbit the Sun, near-Earth objects can sometimes approach close to Earth.
"Keep in mind that" closing "a passage astronomically can be very far in human terms: millions or even tens of millions of kilometers. "
Quick Facts about Asteroids, Comets, and Meteors :
1. A car-sized asteroid hits the Earth on average at least once a year.
2. As ice comets fly around the solar system, their outer layers sublimate in the heat of the sun and leave behind a glowing trace.
3. NASA estimates that a football-sized asteroid collides with our planet once every 2,000 years or more.
4. Some of the larger cosmic rocks in the Asteroid Belt can be 583 miles long
5. A meteor that survives a fiery descent through the earth's atmosphere is known as a meteorite.
