A “potentially dangerous” asteroid the size of a football stadium will fly past our planet in the early hours of tomorrow morning (December 4) – and you can watch it live.

The gigantic space rock, moving at about 27,500 miles per hour (44,300 kilometers per hour), will reach a minimum distance of 1.37 million miles (2.2 million kilometers) from Earth at 12:27 a.m. ET – its closest approach our planet record, loudly NASA’s Jet Propulsion Laboratory (JPL)..
