New data suggest an object known as Kamoʻoalewa was shorn off the moon by a meteor impact before becoming a quasi-satellite of our planet.
Some meteors are fancier than others. Lucky skywatchers in the southeastern US were treated to a fantastic fireball on Tuesday night. Data from NASA shows it was quite a whopper, traveling 186 miles (300 kilometers) through the air.
At least 10 fireballs were reported around the world on Sept. 24 (going by local time), according to the American Meteor Society, which catalogs all fireball events reported by at least five eyewitnesses.
