The Fifth Gas Giant is a hypothetical planet proposed as part of an enhanced version of the Nice Model, a theory that describes the early evolution of the Solar System. This model, first introduced in 2005, suggests that the Solar System initially had five giant planets rather than the four we observe today (Jupiter, Saturn, Uranus, and Neptune). The Fifth Gas Giant is thought to have been ejected from the Solar System during a period of orbital instability approximately 4 billion years ago.
