Lava-Covered Planet Has 8.5 Hour 'Year'

A newly discovered planet has one of the shortest orbital periods ever detected by astronomers, speeding around its star once every 8.5 hours.

Kepler 78b was discovered after scientists examined more than 150,000 stars monitored by NASA's Kepler Telescope. More at Mail Online.
