A massive 420-foot asteroid as big as skyscraper is expected to come terrifyingly close to Earth in the midst of frequent small asteroid sightings. Discovered in 2019, the Asteroid 2019 AV13 is expected to pass by earth at 21:21 on August 20,2022. The AV13 is travelling towards the earth at a staggering speed of 32400 kilometers per hour. It is one of the largest asteroids that will pass by Earth this year.
Although this asteroid will not impact the Earth, it is still classified as a ‘Potential Hazardous Asteroid’ due to its sheer size and the close proximity with which it will pass Earth. Asteroid which comes closer than 28 million miles from Earth’s orbit are classified as potentially hazardous asteroids.
As per reports the asteroid is part of the Apollo group of asteroids and orbits the Sun in approximately 482 days. Scientists say asteroids are left over chunks which remained after the formation of planets. Most of the asteroids can be found orbiting around the sun in the asteroid belt between Mars and Jupiter. According to NASA, The Center for Near Earth Object Studies (CNEOS) observes the sky for any potential hazardous asteroids, predicts their trajectories and carries out impact hazard assessments.
With so many asteroids hovering left and right past the Earth since many days, scientists realize it is question of when and not if an asteroid will strike the earth. The Earth witnessed four different asteroids approaching dangerously close to it in the last week and with the threat of extinction looming over our heads, NASA is testing various strategies to build planetary defense mechanism which can counter asteroid strikes.
NASA states that “An asteroid on a trajectory to impact Earth could not be shot down in the last few minutes or even hours before impact as no known weapon system could stop the mass because of the velocity at which it travels and are extremely fast-moving objects with a speed of 15000-35000 kms per hour. Changing its direction will be impossible due to high velocity of the space rocks.
There are hundreds of smaller but equally deadly stones heading in the direction of our planet which will basically cause an asteroid rain, multiplying the problem. As a result, it has become critical to focus on detection and monitoring their path to assess the risk. However, NASA is developing a new technology that will hit an asteroid and change its trajectory so it does not hit the Earth. As per latest report The DART mission by NASA has sent a rocket in space to collide with an asteroid named Didymos. The collision is scheduled for between September 26 and October 2, 2022, if successful it should improve our capability in dealing with asteroids approaching closer to us.
