For the first time ever, NASA will try to knock an asteroid out of orbit as part of a planetary defense test.

The probe, designed to knock the asteroid out of the course, is set to start between 2020 and 2021 and reach the asteroid in October 2022, Thrillist reports.

The probe will travel about 4 miles per second.

NASA has joined the European Space Agency (ESA) to try to knock an asteroid known as Didymoon out of its orbit around a major asteroid named Didymos. The Double Asteroid Redirect Test (DART) project involves landing a probe on the asteroid and then measuring "momentum transfer" by examining the crater back on the asteroid surface of the probe.

The researchers chose a space rock that is around the size of the large pyramid of Giza (the smallest asteroid a probe will land on) and seven million miles away from the ground, so there's no need to panic yet.

"We better understand whether this technique can be used even for larger asteroids that gives us the assurance that we could protect our home plan, if needed," explained ESA's Hera project researcher Michael Küppers in a statement.

NASA unveiled plans for the mission in 2018, but ESA just announced their plans to work together on critical follow-up research.
