Astronomers say they have discovered more than 100 new moons around Saturn, possibly the result of cosmic smashups that left debris in the planet’s orbit as recently as 100 million years ago. The gas giant planets of our solar system have many moons, which are defined as objects that orbit around planets or other bodies that are not stars. Jupiter …
