NASA asteroid WARNING: Great Space Rock on Earth Science | News



Asteroid, called Asteroid 2018 VA2, will close to Earth on Friday, November 10, shortly after 1.01 am (UTC).

NASA expects the asteroid to fly at a fast speed and its size could be a potentially dangerous object.

Astronomers at California's Jet Propulsion Laboratory (JPL) in California estimate that the asteroid measures from 32 to 74 meters (10 meters and 23 meters).

Past asteroid and meteor impacts indicate that space rock is small, with a diameter of 65.5 meters (20 meters), can cause great damage.

An incident in Chelyabinsk in 2013 in Russia is a great example of the potential for chaos – about 1,500 people were injured when a meteor exploded in Chemabinsk at 65.5 meters.

Matija Cuk, an astronomer at the University of British Columbia in Canada, said: "A smaller object – about 20 meters in diameter – hit the Chelyabinsk region of Russia and caused more than 1,000 injuries.

"Most of the injuries occurred when the explosion destroyed the windows and hit the observers in the buildings that were looking into the fiery ball.

"Fortunately, no reports of death due to the influence of Chelyabinsk."

Fortunately for the Earth, Asteroid VA2 will not come close enough to the planet, even though it would approximate the Earth's approach.

Closed ground approaches are used to describe comets or asteroids on trajectories that bring them incredibly close to the planet, but without the risk of impact.

As NASA points to the cosmic scope of things, close approaches can still be "millions or even tens of millions of kilometers".

In the case of Asteroid VA2, the space scale will reach 0.00480 astronomical units (au) or 1.87 of the Moon's distances (LD) of the Earth.

One astronomical unit describes the amount of space between the Earth and the Sun – about 93 million kilometers (149 million kilometers).

Asteroid VA2 will shorten tomorrow to just 446,187 km (718,069 km).

The distance is about 1.87 times the distance from Earth to Moon.

According to JPL, the asteroid accelerates through the solar system at a speed of 14,920 km / h or 6.6 km per second.

Once the asteroid has made the closest possible approach to Earth, it will again approach the Moon around 6.52 am GMT (UTC).

The space rock will then descend around the Sun and return to Earth's vicinity on October 21, 2026, March 25, 2027, and October 10, 2034.

Asteroid finally visited the planet on 24 October 2005, 23 February 2003 and 2 April 1993.

The news comes after NASA has discovered three major asteroids that will cross Earth on Saturday, November 10th.
