Two New Moons Found Orbiting Uranus

Astronomers have discovered two small moons orbiting Uranus, bringing to 17 the number of moons circling the seventh planet.

The larger moon measures only 100 miles across, the smaller only 50 miles. Unlike the planet’s other moons, they orbit Uranus at a crazy angle, alternately rising high above and then plunging far below the plane occupied by most solar system objects.

Planetary satellites like the two new ones, known as irregular moons, have already been discovered orbiting Jupiter, Saturn and Neptune.
