NASA said: “Some asteroids and comets follow orbital paths that take them much closer to the Sun and therefore Earth – than usual.
“If a comet or asteroid’s approach brings it to within 1.3 astronomical units of the Sun, we call it a near-Earth object.”
NASA predicts Asteroid CO2 will make its approach to Earth tomorrow (February 19) around 8.36pm GMT (3.36pm EST).
When this happens, NASA said the asteroid will be flying by at speeds of about 15.35km per second.
In other words, the asteroid is hurtling towards us at about 34,336mph (55,260km/h).
