A huge asteroid the size of a BUS today will make an extremely close approach to the Earth

A huge BUS-sized asteroid will make an extremely close approach to Earth today, and astronomers discovered it just three DAYS ago.

  • The asteroid, named 2022 NF, has a diameter of 5.4 to 12 meters.
  • It will approach our planet at a distance of 54,843.9 miles around 14:45 Moscow time.
  • Experts only discovered the asteroid on July 4 using telescopes in Hawaii.

Huge asteroid the size of London The bus will make a very close approach to Earth today, despite being detected just a few days ago.

According to the agency, the asteroid, named 2022 NF, will approach our planet at a distance of 54,843.9 miles around 14:45 Moscow time. NASA.

By comparison, that’s just over a quarter of the distance to the Moon at its closest point to Earth, which is 225,623 miles away.

Fortunately, NASA calculations show that a huge space rock will safely pass our planet, although the space agency has not discounted the possibility of an asteroid impact in the near future.

The asteroid, named 2022 NF, will come within 54,843.9 miles of our planet at around 2:45 pm BST, according to NASA (file image).

What is a “potentially hazardous” asteroid?

A Potentially Hazardous Asteroid (POA) is an asteroid whose orbit approaches Earth closer than 0.05 AU. (about 7.5 million km).

It is also at least 100 meters (300 ft) in diameter.

The International Astronomical Union claims that there are about 1,500 potentially dangerous asteroids.

While they do not pose a threat to Earth at the moment, such large asteroids could cause havoc if they land on our planet, especially in densely populated areas.

It is believed that one of them collides with the Earth every 200-300 years.

2022 NF was detected using data from the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), a system of cameras and telescopes based in Hawaii.

Even though it made its closest approach to Earth today, it is surprising that the asteroid was only identified on July 4th.

Measurements show that the diameter of the asteroid is between 17.7 and 39.3 feet (5.4 to 12 meters).

At the top of this score, the 2022 NF is about the same size as the original London Routemaster bus!

During close approach, the asteroid will move at a breakneck speed of 24,606 miles per hour – about 12 times faster than a bullet.

Although the likelihood of this asteroid colliding with Earth is extremely low, NASA does not discount the possibility of an asteroid impact in the near future.

NASA detects about 30 new “near-Earth objects” (NEOs) every week, and at the beginning of 2019, a total of more than 19,000 objects were detected.

However, the space agency has warned that its NEO catalog is not complete, meaning that an unforeseen collision could happen “at any time.”

NASA explained: “Experts estimate that an object the size of the one that exploded over Chelyabinsk, Russia in 2013 — about 55 feet (17 meters) in size — occurs once or twice a century.

2022 NF was detected using data from the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), a system of cameras and telescopes based in Hawaii.

“It is expected that collisions with larger objects will occur much less often (on a scale from centuries to millennia).

“However, given the current incompleteness of the NEO catalog, an unpredictable impact, such as the Chelyabinsk event, could occur at any time.”

To prepare for such a collision, NASA recently launched its first-ever “planetary defense” spacecraft to deflect an asteroid 6.8 million miles from Earth.

The US$325m (£240m) Double Asteroid Redirection Test (DART) mission was launched in November 2021 and will take 10 months to complete the nearly seven millionth journey into deep space.

The probe will crash into the small asteroid Dimorphos, which orbits a larger asteroid called Didymos, at 15,000 miles per hour (24,100 km/h) in September 2022.

When the 1,210-pound space probe collides with Dimorphos, the plan is to change the speed of the “moon star” by fractions of a percent, echoing the plot of the Bruce Willis film Armageddon.

Although the 525-foot-wide space rock poses no danger to Earth, NASA wants to measure the change in the asteroid’s orbit caused by the collision.

This demonstration of “planetary defense” will serve as the basis for future missions that could one day save the Earth from a deadly asteroid strike.

WHAT IS THE NASA DART MISSION?

DART will be the world’s first planetary defense test mission.

It heads for the small lunar asteroid Dimorphos, which orbits a larger companion asteroid called Didymos.

When it gets there, it will intentionally crash into an asteroid to change its orbit slightly.

While none of the asteroids pose a threat to Earth, DART’s kinetic impact will prove that a spacecraft can autonomously navigate to and kinetically impact a target asteroid.

Then, using ground-based telescopes to measure the impact of an asteroid system impact, the mission will enhance modeling and forecasting capabilities to help us better prepare for a real asteroid threat, should it ever be detected.

DART will arrive at Dimorphos in October 2022, where it will deliberately crash into an asteroid at 15,000 mph.  This collision will change the speed of Dimorphos in its orbit around Didyma by a fraction of one percent, changing the orbital period by several minutes.
