NASA has said on its Jet Propulsion Laboratory (JPL) website that the 2021 KT1 asteroid could be around 186 metres in size. This is twice as big as the Statue of Liberty, which is 93 metres in height.
The asteroid is not likely to hit the Earth as it would be 4.5 million miles away at the closest point. However, NASA considers any asteroid potentially hazardous when it comes within 4.6 million miles of the Earth and is larger than 150 metres.
There aren’t any references to confirm whether or not the asteroid would affect the Earth. Nonetheless, NASA says that people should not be overly concerned about a Near-Earth Object (NEO) such as an asteroid impacting the Earth. “The threat to any one person from auto accidents, disease, other natural disasters and a variety of other problems is much higher than the threat from NEOs,” the space agency noted on its Center for Near Earth Object Studies (CNEOS) website.
Scientists, however, believe that chances of the Earth being impacted by NEOs over long periods of time are “not negligible” and thus NASA and other space agencies around the world actively monitor asteroid and comet moments.
In addition to the 2021 KT1, some smaller asteroids are passing near the Earth in the coming days. Those asteroids are expected to be of up to 21 metres in size.
