The outer Solar System has been a busy place lately, with the ongoing Cassini mission at Saturn and New Horizons’ recent spectacular flyby of Pluto. Literally in-between those two worlds, however, it has been […]

The Early Solar System Could Have Hosted a Fifth Giant Planet, According to New Study

Artist’s impression of a rogue gas giant planet, free-floating in interstellar space. According to a new study, the early Solar System hosted a fifth gas giant planet besides Jupiter, Saturn, Uranus, and Neptune, which was eventually ejected into interstellar space through the gravitational interactions with the rest of the Solar System’s giant planets. Image […]
