Korea has been celebrating the thanksgiving holiday of Chuseok this week.
And as China celebrated its own harvest festival Wednesday, people near Shangri-La in the country's southwest, looking at the full moon, saw a meteoroid light up the sky and explode.
NASA recorded the object at an altitude of 37 kilometers traveling at about 14-and-a-half kilometers a second.
The meteor turned into a giant ball of fire, exploding with a force equal to 540 tons of TNT.
That's about half the power of the weapon used by North Korea in its first nuclear test.
Some witnesses said the blast was strong enough to cause some buildings to shake.
