Fifth Gas Giant
The Fifth Gas Giant, also called as the Fifth Giant, is a hypothetical planet that existed 4 billion years ago. The planet was theorized in 2011.
Theory[edit]
The theory of a fifth gas giant in our Solar system came from a theory theorized in 2011, and states that an extra ice giant was placed right between Uranus and Saturns orbit. Over time, the hypothetical planets mass exerted force on Saturn and Uranus, eventually tightening the 3 planets together, and with enough gravity, the gravitational pull of Saturn and Uranus flung the gas giant out of our Solar system.[1]
Characteristics[edit]
It's hypothetical, but online sources state the gas giant had a mean radius of 23,500 kilometers (km). Circumference is approximately 147,655 kilometers, and its dimensions are approximately 47,000 Kilometers.
Composition[edit]
Using studies of Voyager 2's study of Uranus and Neptune, the hypothetical composition of the most common gases most likely prevalent in the gas giants atmosphere are Hydrogen, Methane, Helium, and Ammonia.
Whereabouts[edit]
The planet may’ve been trapped by a star's gravitational pull, and became an already discovered exoplanet; could also be an already discovered rogue planet, or was possibly ripped up by a stars gravity. Another theory suggests it could have not completely been knocked out of the suns gravitational pull, and could’ve been re-orbited in an elliptical path, possibly becoming Planet X.
