Meteor explodes over Russia

The meteor exploded in the sky; Fragments may have hit the Earth. Why are so many big meteors seen over Russia?

Twilight Meteor over Russia, June 21, 2018.

A brilliant meteor was seen on June 21, 2018, in several Russian cities, including in Lipetsk, which is southeast of Moscow. The fireball produced an incredible trail of smoke that remained visible for several minutes. NASA records indicate that the event took place on June 21st at 01H16M20 UTC (Universal Time). Sensors have detected that the space rock produced an explosion equivalent to 2.8 kilotons. This explosion size corresponds to the disintegration of a small asteroid about 13 feet (4 meters) in diameter. This size is in contrast to the estimated 20-metre asteroid that exploded in the air over Chelyabinsk, Russia, in February 2013. The infrasound sensor detectors recorded the low frequencies produced by the explosion of the space rock that entered the Earth's atmosphere. Some people filmed the meteor with car dashboard cameras… Although intense friction with the air caused the disintegration of most of the space rock, it is possible that small fragments have reached the surface of the Earth.

Why do so many meteor events occur over Russia? Russia is the largest country in the world, so its large territorial extent makes it the target with the highest probability of a space rock reaching beyond the oceans. About 70% of the surface of our planet is covered by water, which means that most meteors fall into the sea. Science centers and museums around the world Celebrate Asteroid Day on June 30th, an event to raise awareness and educate our communities about these spatial rocks… Source
