An asteroid called 2018 CC made its closest approach to Earth on Tuesday, February 6, at 3:10 p.m. EST. Coincidentally, the SpaceX Falcon Heavy rocket went up about a half hour later, sending a Tesla car with a Starman mannequin at the wheel off into the asteroid belt.

Another larger visitor named asteroid 2018 CB will pass by Earth today, February 9, at around 5:30 p.m. EST. It is between 50 and 130 feet (15 and 40 meters) and will pass Earth at a distance of 39,000 miles (64,000 km). It will be five times closer to us than the Moon.

It is not the gigantic asteroids of movies, but it is probably larger than the asteroid that entered the atmosphere over Russia, almost exactly five years ago. On February 15, 2013, a near-Earth asteroid of roughly 65-feet (20-meters) exploded as it entered the atmosphere, and the shockwave caused damage to over 7,200 building and injured nearly 1,500 people from shattered glass.

It didn’t even hit the Earth. Imagine what it would have caused if it did hit our planet. It is the stuff of movies. For now.
