When a mysterious asteroid entered our solar system, experts had one chance to find out as much about it as they could.
Researchers looked at data from every earthquake that's magnitude 7 or higher and noticed a correlation between severe quakes and Earth's rotation.
In addition to it's scientific discoveries, Cassini also proved to be a productive photographer. It took more than 450,000 photos on its journey.
The earthquake struck just before 6 a.m. local time Tuesday.
