NASA asteroid tracker: A GIANT space rock just flew over Earth at more than 15,100MPH –

The , dubbed by NASA Asteroid 2019 JN2, zipped past the Earth on an “Earth Close Approach” trajectory. NASA said the asteroid flew by our home planet in the wee morning hours (Wednesday, May 15). At its closest, the space rock approached the Earth around 3.15am BST (2.15am UTC). When this happened, the asteroid reached terrifying speeds of around 6.77km per second or 15,144mph (24,372kmh).

Asteroid JN2 is a so-called “Near-Earth Object” or NEO asteroid.

NEOs are all comets and asteroids which orbit the Sun from a maximum distance of 120.8 million miles (194.5 million km).

These rocky objects hurtle around the inner circles of the solar system without flying past the Asteroid Belt in-between Mars and Jupiter.

NEOs like Asteroid JN2 occasionally intersect Earth’s own orbit of the Sun.


These nail-biting flybys have been known at times to pass as close, if not closer, than the Moon.

But was there anything to fear from today’s flyby of Asteroid JN2?

Thankfully, you most likely slept soundly tonight because ’s asteroid trackers at the California Jet Propulsion Laboratory (JPL) did not expect any cataclysmic impact to occur.

At its closest, Asteroid JN2 approached the Earth from a distance of 0.01809 astronomical units.


One astronomical unit describes the average distance from the Earth to the Sun – an approximate 93 million miles (149.6 million km).

This means Asteroid JN2 passed over our heads from a distance of 1.68 million miles (2.7 million km) from Earth.

In other words, the  rock flew past from 7.04 Lunar Distances (LD) or just slightly more than seven times as far as the Moon is.

NASA said: “As they orbit the Sun, Near-Earth Objects can occasionally approach close to Earth.


“Note that a ‘close’ passage astronomically can be very far away in human terms: millions or even tens of millions of kilometres.”

Asteroid JN2 is an Apollo-type asteroid, meaning it has orbit similar to that of Asteroid 1862 Apollo.

The space rock measures somewhere in the range of 65.6ft to 144.3ft (20m to 44m) in diameter.

After today’s flyby, the asteroid will visit the Earth again on the morning of April 18, 2020.
