Asteroid May Collide With Earth In Decades, ESA Warns

An asteroid has just been added to the ESA's Risk List which astronomers believe could collide with the Earth in just a few decades.

Asteroids known as Near Earth Objects (NEOs) are closely monitored by space agencies as some of the most dangerous objects in the atmosphere.

One particular, known as the asteroid 2019 SU3, was just added to the ESA's Risk List, thanks to the high chance it could hit Earth as soon as 70 years from now.

At the time of writing, there are currently 897 Near Earth Objects being monitored by the European Space Agency.

As they say on their website:

The Risk List is a catalog of all objects for which a non-zero impact probability has been detected.

Each entry contains details on the Earth approach posing the highest risk of impact (as expressed by the Palermo Scale). It includes its date, size, velocity and probability.

As well as sitting high on the Risk List, the asteroid 2019 SU3 is also on ESA's Priority List, which 'addresses the problem of efficiently planning and executing NEO follow-up observations. It classifies the need to observe especially newly discovered objects in four categories, urgent, necessary, useful and low priority. '

According to the ESA, the asteroid SU3 is expected to come within 0.00079 astronomical units to Earth, which is approximately 73,000 miles, or 30 percent of the distance between the Earth and the moon.

Scientists predict it will pass through our Earth in 2084. According to NASA, asteroids that come within 0.05 astronomical units of Earth, measuring at least 460 feet in diameter, are known as 'potentially hazardous' NEOs.

Last month, the ESA warned that even a small asteroid colliding with Earth could cause 'serious devastation.'

In order to protect Earth and catch the rocks before they make landfall, ESA has teamed up with other groups to search for asteroids, as well as developing methods to divert space rocks away from our planet.

The agency's warning came after NASA said an asteroid larger than the Empire State Building was passing 'close' by our planet. The space rock, called the 2000 QW7, skimmed past Earth at more than 14,000 miles per hour on September 14 – I mean, it was about 3 million miles away, but still, NASA considers it to be a 'close approach.'

NASA and the ESA are both tracking asteroid 2019 SU3 and its future plans to skim past Earth.
