NASA – Asteroids – Warning: Giant Space Rock on Earth Science | news



The rogue asteroid, baptized by the US space agency Asteroid 2018 VE4, will appear closest to Earth at 5:24 GMT (UTC). Today's flyby in the afternoon marks the fifth visit of the asteroid in Earth's space, after flying past it for the first time on September 18, 1947. NASA astronomers do not expect VE4 to swing straight into our homeworld, but its destructive potential is still impressive. NASA's Jet Propulsion Laboratory (JPL) scientists estimate space rock anywhere from 75.4 feet to 164 feet (23 to 50 meters).

An asteroid with a length of up to 164 feet is longer than six London double-decker buses one line and the Arc de Triomphe in Paris.

The space rock may not be a planet killer, but even the bottom end of NASA's estimate poses a potential threat to heavily populated areas.

In 201

3, more than 1,000 people were injured when a 65 meter wide meteor broke the atmosphere and broke out over the city of Chelyabinsk in Russia.

The meteor's mighty explosion smashed windows all over the city and smashed shards of broken glass into the faces of the spectators.

Matija Cuk of Cornell University in New York are rare effects with these smaller asteroids and there are no known examples of them being deadly.

The space expert said, "Smaller meteorites that touch the ground pose a very minor threat, and it has never been reported that a human was killed by a small meteorite.

"I heard a story a dog was killed by a meteorite that fell in 1911 in Nakhla, Egypt, and there were also cases of material damage.

"Nevertheless, traffic, pollution and even lightning are far more dangerous than small meteorites."

Fortunately, the risk of asteroid 2018 VE4 penetrating the Earth with brute force is very low.

Asteroid VE4 is a Near Earth object, meaning that its closest orbit to the Sun is less than 120.8 million kilometers

NEOs are often located on orbits that bring them close to Earth Earth Close Approaches, but for the most part they are safe for humans.

Today the space rock does not come closer than 0.03841 astronomical units (au) or 14.95 lunar distances (LD) of the earth.

This equates to nearly fifteen times the distance from Earth to the Moon or 3.5 million miles (5.74 million km).

NASA said, "How to orbit Mars Sun, near-Earth objects may occasionally approach Earth.

"Note that a" near "passage can be very far from a human perspective: millions or even tens of millions of kilometers."

The asteroid is now at breakneck speeds in excess of 10.759 miles per hour, or 4, 81 km per second through the void roll.
