The New Horizons (NH) flyby of the Pluto–Charon binary planet and its system of four small
surrounding satellites in mid-2015 revolutionized our knowledge of this distant planet and its …

Hitherto, rings have been found exclusively around the four giant planets in the Solar
System. Rings are natural laboratories in which to study dynamical processes analogous to …

Pluto and Charon are strikingly diverse in their range of geologies, surface compositions,
and crater retention ages. This is despite the two having similar densities and presumed …

Kuiper belt objects (KBOs) with absolute magnitude less than 3 (radius≳ 500 km), the dwarf
planets, have a range of different ice/rock ratios, and are more rock-rich than their smaller …

The planet Neptune and its largest moon Triton hold the keys to major advances across
multiple fields of Solar System science. The ice giant Neptune played a unique and …

The topography of Neptune's large icy moon Triton could reveal important clues to its
internal evolution, but has been difficult to determine. New global digital color maps for …

Neptune's moon Triton shares many similarities with Pluto, including volatile cycles of N 2,
CH 4 and CO, and represents a benchmark case for the study of surface-atmosphere …

We report on an ephemerides update for the irregular satellites of Uranus and Neptune,
including Nereid. Our data set contains ground-based and Voyager 2 position …

The number of planetary satellites around solid objects in the inner solar system is small
either because they are difficult or unlikely to form or because they do not survive for …

We study the tidal disruption of binaries by a massive point mass (eg, the black hole at the
Galactic center), and we discuss how the ejection and capture preference between unequal …
