And when this happens, the asteroid is expected to peak at speeds of around 26,574.8mph (42,768kph) or 11.88km per second.
NASA said the space rock will approach the Earth tonight from a distance of 0.00443 astronomical units (au).
One astronomical unit measures approximately 93 million miles (149.6 million km), which is the distance from the Earth to the Sun.
Asteroid GN will trim this down to just 411,794 miles or 662,718.6km.
