Giant 280ft asteroid will skim past Earth TODAY in close flyby travelling at 30,420 miles per hour

  • Asteroid 2013 MD8 is expected to skim past Earth on Wednesday, NASA said
  • The space rock has a diameter of nearly 280ft, which rivals the size of Big Ben
  • It will fly by our planet at about 13 lunar distances, or just over 3 million miles

The asteroid, dubbed 2013 MD8, is expected to skim past Earth at just over 3 million miles away, or about 13 times the distance between Earth and the moon, at 12:55pm (ET) on Tuesday.

The huge space rock is expected to make a ‘close approach’ to Earth, but its trajectory should see it soar safely by.

NASA considers an asteroid to be ‘hazardous’ if they come within 4,600,000 miles of our planet.

Asteroid MD8 falls under the category of a ‘near-earth object’ (NEO), which NASA describes as all asteroids and comets that orbit within 30 million miles of Earth.

However, there is little to be worried about, even with MD8 being a near-earth-object.

The massive asteroid, dubbed 2013 MD8, will soar past Earth at a dizzying speed of 30,422 miles per hour. It falls under the category established by NASA of near-earth-objects

With a diameter that’s close to 280ft, Asteroid 2013 MD8 rivals the Big Ben clock tower in its size, which stands at 320ft. The space rock likely falls under the category of near-earth-object

‘No human in the past 1000 years is known to have been killed by a meteorite or by the effects of one impacting,’ scientists at NASA’s Jet Propulsion Laboratory explained.

‘NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small.

‘In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years,’ they continued.

The agency believes that out of the more than 600,000 known asteroids in our solar system, roughly 16,000 are NEOs.

MD8 also falls under the category of a ‘potentially hazardous object,’ which are those that reach a minimum distance less than .05 au from Earth and have an absolute magnitude (H) of 22.0 or brighter.

Asteroid 2013 MD8 has an absolute magnitude of 24.2.

WHAT COULD WE DO TO STOP AN ASTEROID COLLIDING WITH EARTH?

Currently Nasa would not be able to deflect an asteroid if it were heading for Earth but it could mitigate the impact and take measures that would protect lives and property.

This would include evacuating the impact area and moving key infrastructure.

Finding out about the orbit trajectory, size, shape, mass, composition and rotational dynamics would help experts determine the severity of a potential impact.

However, the key to mitigating damage is to find any potential threat as early as possible.

Nasa is currently moving forward with a refrigerator-sized spacecraft capable of preventing asteroids from colliding with Earth. A test with a small, nonthreatening asteroid is planned for 2024.

This is the first-ever mission to demonstrate an asteroid deflection technique for planetary defence.

The Double Asteroid Redirection Test (DART) would use what is known as a kinetic impactor technique—striking the asteroid to shift its orbit.

The impact would change the speed of a threatening asteroid by a small fraction of its total velocity, but by doing so well before the predicted impact, this small nudge will add up over time to a big shift of the asteroid’s path away from Earth.
