A small asteroid discovered Saturday morning, determined to head for Earth, impacted the planet's atmosphere just a few hours later, according to NASA.

The cosmic boulder, named asteroid 2018 LA (and previously listed as ZLAF9B2), was estimated to be only about 6 feet (2 meters) across. It was first spotted by the Catalina Sky Survey in Arizona.
