Another pair of asteroids is going to whiz past Earth on 14 September — Bigger, faster but further away

• Dual asteroids are rare and even more infrequent when they are big in size.
• Asteroid 467317 (2000 QW7) is as big as the Shanghai Tower — the second tallest building in the world.
• The two asteroids are set to pass by Earth in the same 24-hour window on 14 September 2019.

Two asteroids already whizzed past Earth this week and now, two more are set to fly by on 14 September 2019. But this time around, the pair will be bigger and faster — but also further away.

The first asteroid, which will be bigger than the Empire State Building and India’s own Statue of Unity, is set to whiz past Earth at a speed of 23,000 kilometers per hou.

The National Aeronautics and Space Administration's (NASA) Jet Propulsion Laboratory (JPL) estimates that the asteroid dubbed $4 could be anywhere between 290 meters to 650 meters in diameter.

So, at its largest, the asteroid measures around the same size as the Shanghai Tower — the second tallest building in the world.

And, it won’t be alone.

In the same 24-hour window, Asteroid $4, estimated to be between 120 meters to 260 meters in diameter, will be flying past the planet at a speed of 51,696 kilometers per hour.

Both them of them are going to be around 5.3 million kilometers from Earth as they make their visit.

This is the second time in the span of a month that dual asteroids are whizzing past the planet. On 28 August 2019, two asteroids — $4— flew past Earth within hours of each other.

Don’t fear, but who’s gonna be there?

NASA’s Center of Near Earth Object Studies is tracking both the asteroids and do not seem to pose any danger as of now.

Should that change, NASA’s current defense plan against any incoming asteroids is the Double Asteroid Redirection Test (DART) — which is still under development.

Elon Musk, Founder and CEO of SpaceX, $4 that, “A big rock will eventually hit Earth eventually and we currently have no defence.”

In June, astronomers have already shown that in case an asteroid poses a threat — then can move people out of harm’s away in time.

When asteroid 2019 MO was barrelling towards Earth on 22 June 2019, scientists at the University of Hawaii used the ATLAS and Pan-STARRS telescopes to detect the asteroid’s path.

They were able to confirm that the asteroid would burn up in the atmosphere, over the ocean, 400 kilometers away from San Juan.

$4, which is actually two telescopes in Hawaii — one on Big Island and the other on Maui — scans the skies every two days for asteroids that could be heading towards Earth.

It claims to be able to detect small asteroids 12 hours in advance and bigger asteroids will be on their radar days before they’re anywhere near Earth.
