  • Hippocamp, a previously undetected moon of Neptune, has a peculiar location and a tiny size relative to the planet’s other inner moons, which suggests a violent history for the region within 100,000 kilometres of the planet.

  • In the Solar System, planetary rings tend to lie within a few radii of their host body, because at these distances gravitational accelerations inhibit satellite formation. One of the best known exceptions to this rule is Saturn's E ring, a broad sheet of dust continuously supplied by source satellites that fades from view at five to ten planetary radii. An enormous ring associated with Saturn's outer moon Phoebe is now reported; it extends from at least 128 to 207 Saturn radii.

  • Infrared imaging reveals all of Saturn’s faint, outermost ring, showing that it is composed principally of small dust particles and suggesting that particle temperatures are increased because of the radiative inefficiency of the smallest grains.

  • A network of parallel ridges on the northwestern border of Sputnik Planitia on Pluto are the traces of debris material deposited by a glaciation of icy nitrogen that happened early in Pluto’s history, and left there once the N2 ice disappeared by sublimation.
