NASA Asteroid Tracker: Asteroid Finds Two Days Ago Crosses Earth Today Science | News



Asteroid in the small morning hours (Friday, March 29). NASA's asteroid trackers at the JPL-based California JPL have said the space rocket has flown around Earth around 2.25 hours (UTC) today. After the initial observation on Wednesday, NASA tracked the asteroid 66 more times to outline its speed, size and trajectory.

The US space agency has determined that the asteroid fired near the Earth at a top speed of 6,23 km / h or 13,936 km / h.

NASA also calculated space scale measures somewhere in the range of 55.7 to 121.4 ft

An asteroid at the top of this estimate is up to 4.4 times longer than the London double-decker bus or 18 times longer than the Queen Size bed.

According to NASA, Asteroid FW is an Apollo object because its orbit is similar to that of the asteroid near Earth 1

862 Apollo.

All asteroids and comets that do this are called "near-ground objects" or NEOs. "When they walk around the Sun, objects near the Earth can sometimes approach near the Earth." "Not that a" close "astronomical passage can be very far in the human sense: millions or even tens of millions of miles.

Fortunately, there is no risk of the asteroid striking our native world soon.

Even on its nearest day, NASA said that the FW asteroid just approached the Earth from a distance of 0.02069 astronomical units (au). 19659003] An astronomical unit roughly translates 93 million miles (149.6 million kilometers) or the distance from Earth to the Sun. before us

The asteroid FW reduced this significantly to only 1.92 million miles (3.09 million kilometers).

In other words, the asteroid will shoot around the Earth about eight times, as long as the moon is

But this is not the first time NASA believes the space stone has passed Earth.

According to JPL, the orbit of the asteroid shows that it was past us on February 10, 2017.

And after today's approach, Rock will again visit the Earth's Corner of Space on 15, 2021, and May 11, 2021. [19659017]
