Scientists discover 12 new moons around Jupiter


Jupiter's massive gravitational attraction has collected some fresh followers.
While looking for a possible ninth planet, scientists instead discovered another 12 moons orbiting the gas giant, per a Monday press release from Carnegie Science. The find brings Jupiter's total number of moons to 79, the most in the solar system.
Eleven of the new moons are pretty normal, orbiting either with or against Jupiter's rotation. But in the release, scientists called one an "oddball" because it lives far out with moons that orbit counterclockwise, but travels clockwise itself.
