According to NASA, the first asteroid, 2016 CZ31, will pass by at 7 p.m. ET (23:00 GMT) on Friday, travelling at an estimated 34,560 mph (55,618 km/h).

Astronomers believe that the asteroid is 400 feet (122 metres) broad at its widest point, making it roughly the width of a 40-story building.

The asteroid will pass approximately 1,740,000 miles (2,800,000 kilometres) from Earth.

This space rock, according to NASA, will come near to Earth again in January 2028, after a few years.

On Saturday, a second, larger asteroid will pass by our planet, though at a greater distance.

This asteroid, known as 2013 CU83, is about 600 feet (183 metres) across at its widest visible point and will pass Earth by around 4,320,000 miles (6,960,000 kilometres).
