Zurich, Switzerland (SPX) Dec 11, 2025
The Solar System is often divided into four inner rocky planets, two gas giants, and two ice giants thought to be dominated by water and other volatiles, but new work from the University of Zurich suggests Uranus and Neptune may contain much more rock than assumed so far. The study indicates that these distant planets can be consistent with interior structures that are either ice rich or rock ri
