A bright fireball over Tokyo explodes with the force of 165 tons of TNT

The sky above Tokyo was illuminated by an explosive alien object early Thursday morning, which some reports also said was accompanied by a sonic boom.

Videos of the event show a spectacular light with green and violet hues that fly over the sky for a few seconds around 2:30 a.m. local time before the light goes out.

“I thought a person living upstairs knocked down a shelf,” said a Japan Times native.

The effects of a likely small asteroid colliding with our atmosphere have been recorded by some of the infrasound monitoring stations set up worldwide and monitored by the Organization of the Comprehensive Nuclear Test Ban Treaty.

The International Meteor Organization reports that the meteorite was visible from a large part of the Japanese Kanto region.

“We were able to calculate an energy source for the incoming asteroid of about (165 tons or 150 tons) TNT,” says an IMO blog post.

The IMO estimates that the space rock could be 1.6 meters in diameter and 1.6 tons in mass. For comparison, the meteorite that exploded over Russia in 2013 and blew out thousands of windows in the city of Chelyabinsk was probably ten to twenty times as massive.

Fireballs are common, although an event large enough to trigger a sonic boom is less likely to occur, especially if it’s over one of the largest cities in the world. Remember to keep an eye on the sky!
