La planete Neuf - Illustration - Planet Nine - Artwork: Vue d'artiste de la planete Neuf. The Ninth Planet is a hypothetical planet of the Solar System indirectly recorded, the existence of which is suggested by observing the orbits of several transneptunian objects. This planet would be gaseous, similar to Uranus or Neptune. A hypothetical planet in the outer reaches of the solar system orbits more than 700 times farther from the sun than earth does. A Super-earth, with an estimated mass of 10 Earths (approximately 5,000 times the mass of Pluto), a diameter two to four times that of Earth, and a highly elliptical orbit with an orbital period of approximately 15,000 years, the planet is shown as a ringed ice giant whose night side is illuminated by lightning and aurorae powered by galactic cosmic rays.
