NASA Asteroid Warning: 390 Foot Giant Asteroid on Earth, Close Focus | Science | News

The monstrous asteroid named NASA Asteroid 2009 WB105 will make its appearance near Earth around 12.14 pm GMT (UTC) on Sunday, November 25. The flyby of tomorrow marks the first time in three years that the asteroid will visit the corner of Earth in space and scientists are very close. Attention. According to NASA's California-based Jet Propulsion Laboratory, space rock measures about 173.8 feet at 393.7 feet (53-120 meters) in diameter.

At 393.7 feet (120 m), the WB105 asteroid would rise above the 315-foot Big Ben clock tower and the Statue of Liberty in the United States.

In other words, this is roughly the equivalent of 13 Routemaster London buses lined up in a row.

Even at the lower end of NASA's estimate, the asteroid is taller than Nelson's Column in Trafalgar Square and is almost six times longer than a double-weight bus.

The latest impacts of asteroids in the last 200 years show that the space rocks within this calculation can be incredibly catastrophic.

It is believed that the Tunguska event of 1908, which destroyed 772 square miles (2,000 km2) of a Siberian forest, was caused by a meteorite between 164 feet and 328 feet (50 and 100 meters) wide.

And in 2013, more than 1,000 people in the Russian city of Chelyabinsk were injured by shattered glbad windows when a 65-foot wide meteor exploded in the air.

According to the European Space Agency (ESA), space rocks in the range of "tens to hundreds of meters" are some of the most dangerous that scientists know.

The ESA explained: "Any impact of one of these could really damage the city or a populated area.

"But if they are discovered early enough, their point of impact could be estimated with a good degree of precision and measures could be taken to protect people.

"Nowadays, no known object deserves any concern, but many remain undiscovered, so we need to keep searching."

Fortunately, there is no risk of the Asteroid WB105 crashing into our planet in the near future or in the near future.

Tomorrow afternoon, the asteroid will perform the so-called Earth Closing Approach, which means it will approach the Earth 30 million miles (50 million kilometers) from its orbit.

NASA estimates that the WB105 will arrive as close as 0.03893 astronomical units (au) or 15.15 lunar distances (LD) of the Earth just after noon.

An astronomical unit measures approximately 93 million miles (149.5 million km), the distance between Earth and the Sun.

Asteroid WB105 will reduce this distance tomorrow to only 3.6 million miles (5.8 million km).

In an astronomical distance scale, this is a very close contact with the asteroid and means that WB105 is clbadified as a Near Earth Object (NEO).

NASA explained: "While orbiting the Sun, near-Earth objects can occasionally approach the Earth.

"Keep in mind that a pbadage that is closed astronomically can be very far in human terms: millions or even tens of millions of kilometers."

According to NASA's calculations, the space rock is accelerating through space at approximately 42.233 mph or 18.88 km per second.

The asteroid WB105 will cross the planet again on the same date, on November 25, 2021.
