Near Miss Day 2021

Near Miss Day takes place on March 23, 2021. It commemorates the day a huge Asteroid nearly missed hitting the earth on March 23, 1989. The 300-meter (1,000-foot) diameter asteroid missed the Earth by 700,000 kilometers (430,000 mi) passing through the exact position where the Earth was only 6 hours before. If the asteroid had impacted it would have created the largest explosion in recorded history, 12 times as powerful as the Tsar Bomba, the most powerful nuclear bomb ever exploded. It attracted widespread attention as early calculations had its passage being as close as 64,000 km (40,000 mi) from the Earth, with large uncertainties that allowed for the possibility of it striking the Earth.
