Pluto's Polygons

When the NASA's New Horizons spacecraft buzzed by Pluto last year, it revealed tantalizing clues that the dwarf planet might have -- or had at one time -- a liquid ocean sloshing around under its icy crust.

2007 OR10 Is The Largest Unnamed World in Our Solar System

Dwarf planets tend to be a mysterious bunch. With the exception of Ceres, which resides in the main asteroid belt between Mars and Jupiter, all members of this class of minor planets in our solar system lurk in the depths beyond Neptune.

Pluto's Interaction with the Solar Wind is Unique

Pluto behaves less like a comet than expected and somewhat more like a planet like Mars or Venus in the way it interacts with the solar wind, a continuous stream of charged particles from the sun.
