An asteroid that could break apart has a 6 percent chance of raining down on Earth in the next 10 million years.

Astronomers have traced a 2017 fireball over Japan to a massive nearby asteroid that could eventually break up and shower Earth with dangerous meteors.

Time - April - Fireball - Skies - Kyoto

It was around 1 a.m. local time on April 29, 2017, when an exceptionally bright and slow fireball lit up the skies over Kyoto, Japan. Later, a team of researchers from the National Astronomical Observatory of Japan (NAOJ), Kyoto Sangyo University (KSU) and the Nippon Meteor Society found the dust particle that flamed out in grand style that evening had an orbit similar to the double (or binary) asteroid 2003 YT1.

"We uncovered the fireball's true identity," Toshihiro Kasuga, a visiting scientist at NAOJ and KSU, said in a release Wednesday. "The 2017 fireball and its parent asteroid gave us a behind-the-scenes look at meteors."

Team - Research - Monday - Astronomical - Journal

The team's research was published Monday in The Astronomical Journal.
