Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

Abstract The Rosetta spacecraft reached Comet 67P/Churyumov-Gerasimenko (hereafter
67P/CG) in August 2014 at an heliocentric distance of 3.6 au and was then put in orbit …

Non-destructive, non-contaminating, and relatively simple procedures can be used to
measure the bulk density, grain density, and porosity of meteorites. Most stony meteorites …

The dwarf planet Eris is a trans-Neptunian object with an orbital eccentricity of 0.44, an
inclination of 44 degrees and a surface composition very similar to that of Pluto. It resides at …

The discovery of the first interstellar object passing through the Solar System, 1I/2017 U1
('Oumuamua), provoked intense and continuing interest from the scientific community and …

Using precise relative astrometry from the Hubble Space Telescope and the WM Keck
Telescope, we have determined the orbits and masses of the two dynamically interacting …

Aims. The goal of this work is to characterize the ensemble thermal properties of the
Centaurs/trans-Neptunian population. Methods. Thermal flux measurements obtained with …

The Trojan asteroids, a very substantial population of primitive bodies trapped in Jupiter's
stable Lagrange regions, remain quite poorly understood. Because they occupy these orbits …

The outcome of collisions between small icy bodies, such as Kuiper belt objects, is poorly
understood and yet a critical component of the evolution of the trans-neptunian region. The …
