A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

Two space rocks are raising huge scientific questions and may pose some answers regarding the nature of our planet and of another solar system body, Pluto. Pluto has long been under siege by skeptics ...

New research suggests Pluto may have had a “kiss” with its largest moon billions of years ago in a harmless collision. The report, published in “Nature Geoscience,” describes how the minuscule dwarf ...
