Nearly one hundred known asteroids are set to fly past Earth before the end of 2021, NASA says, but asteroid 231937 is set to be the largest and fastest.
However, NASA says the asteroid’s orbit is well known and poses no threat to humans.
According to the space agency, the asteroid will make is closest approach at 16:03 UTC (11:03 a.m. EST), at over two million kilometres away from Earth. NASA notes that this is nearly five times farther than the distance the moon orbits Earth.
It will be close but not nearly close enough.
