Newly discovered far-flung object supports Planet X existence
... so that it never gets too close to the massive planet. This behaviour is already seen with Pluto and Neptune, as Pluto never strays too close to the ice giant even though their orbits cross. "What makes...

Are Earth-like worlds built like Earth?
...but theoretical models of planet formation predict that planets intermediate in size between Earth and Neptune could be gaseous ‘mini- Neptunes,’ rocky ‘Super-Earths,’ or indeed water worlds, thus adding to the uncertainty in planet structures. After...
