Asteroid in the early morning (Friday, March 29). NASA's asteroid trackers at the California-based Jet Propulsion Laboratory (JPL) said the space rock has now covered Earth at 2:25 GMT (UTC). Since first observing on Wednesday, NASA has followed the asteroid another 66 times to determine speed, size, and trajectory.
The US Space Agency has passed the asteroid at a rapid speed of 6.23 km / s (22,530 km / h).
NASA also estimated the space rocks in the range of 55.7 feet to 121.4 feet (17m to 37m) in diameter.
An asteroid at the top end of this estimate is up to 4.4 times as long as the London double-decker bus or 18 times longer than a queen-size bed.
According to NASA Asteroid FW is an Apollo-type object, since its orbit resembles that of the near-Earth asteroid of Apollo 1

This means an asteroid FW occasionally intersects the Earth's journey around the Sun in an "Earth Close Approach."
All asteroids and comets that do this are called Near-Earth Objects or NEOs.
NASA stated, "While they are orbiting the Sun, objects near Earth may occasionally approach Earth.
"Not so a" narrow "passage from a human point of view can be very far away: millions or even tens of millions of kilometers. "

Fortunately, there is no danger that the asteroid will enter our homeland shortly.
NASA said that even in its present time, the asteroid FW had only traveled to Earth from a distance of 0.02069 astronomical units (AU). 19659003] An astronomical unit equates to approximately 93 million miles (149.6 million km) or the distance from Earth to the Sun.

Asteroid FW reduced this considerably to only 3.09 million kilometers.
In other words, the asteroid shoots past Earth about eight times until the moon is
But it is not the first time that NASA believes the space rock has passed Earth.
According to the JPL, the asteroid orbit shows it had flown past us on February 10, 2017.
And after today Approach The Rock will revisit Earth's corner on January 15, 2021 and May 11, 2021.
