25 Heavenly Facts About Our Solar System Everyone Should Know

Pluto is technically a binary system. Its moon, Charon, is massive enough in relation to Pluto that the point around which they orbit is somewhere in between the two.

Jupiter's moon Io, the most volcanically active world in the Solar System, has volcanic eruptions so powerful that they can be seen with large telescopes on Earth.

Moon has its own time zone called Lunar Time Zone and President Richard Nixon was one of the few to have a moon watch.

Pluto's largest moon Charon was named after astronomer James W. Christy's wife, Charlene. It was later discovered that Charon was an existing figure in Greek mythology (the ferryman of Hades, later known as Pluto), and thus the name was kept.

An asteroid impact may have caused Enceladus, Saturn's moon, to wobble and eventually stabilize at a tilt that is 55 degrees "off" from its original orientation.
