The awesome asteroid called Asteroid 2019 LB shot over the earth today (Wednesday, June 12). NASA's asteroid trackers at the California Jet Propulsion Laboratory (JPL) have warned that the asteroid would fly past a so-called near-earth trajectory. The news comes one month after astronomers first observed the rock in space on May 7. And according to NASA's JPL, the asteroid approached the next at 15.38 BST (10.38 EST).
Asteroid LB is an Apollo space rock zipping around the inner circles of the solar system.
The JPL estimates that LB has a diameter in the range of 82 feet to 180.5 feet (25 meters to 55 meters).
At the upper end of NASA's estimate, space rock is roughly comparable to about six and a half London double-decker buses.
And if that's not terrible enough, the asteroid flies around the sun at more than 6.05 km / s.)

On this fast orbit, the asteroid follows a path similar to its eponymous asteroid of 1
And because the asteroid's trajectory does not extend beyond the asteroid belt between Mars and Jupiter's NASA class ifies it as a near-earth object (NEO).
According to NASA, a NEO is an "asteroid or comet with a perihelion distance of less than or equal to 1.3 astronomical units".
An astronomical unit is approximately 93 million miles (149.6 million km), which is the distance between the Earth and the Sun.

What this means Asteroids like LB orbit the Sun from a maximum distance of about 120.8 million miles (194.5 million km).
Occasionally, these imposing space rocks intersect with the Earth's orbit.
NASA said, "While they are orbiting the Sun, near-Earth objects may occasionally approach Earth.
"Note that a & # 39; close & # 39; Passage astronomical in human terms can be very far away: millions or even tens of millions of kilometers. "

How near was the asteroid flying past Earth this afternoon? 19659003] In other words, the space rock shot past safely from a distance of more than 3.49 million km.
The distance in question is about 9.09 times the distance between the Earth and the Moon.
