An asteroid with a diameter equal to the height of the Golden Gate Bridge will pass Earth on the evening of the October 2021 full moon, also known as the Hunter's Moon.

The space rock designated 1996 VB3, with a diameter of 220 meters, will pass Earth on the evening of October 20. It will reach a minimum distance of around 2 million miles (3.2 million km) from Earth. That's just under nine times the distance between Earth and the moon.
