TL;DR: A spacecraft flyby of an asteroid reveals a high-density body that is more like a planetesimal than a rubble pile, which contrasts with smaller asteroids visited by previous spacecraft, which are probably shattered bodies, fragments of larger parents, or reaccumulated rubble piles.

TL;DR: In this paper, the photometric and spectrophotometric properties of the nucleus of the comet 67P/Churyumov-Gerasimenko (67P) were derived from the OSIRIS imaging system, which consists of a WAC and a Narrow Angle Camera (NAC).

TL;DR: In this article, the authors investigate the insolation of the cometary surface in order to predict the sublimation of water ice, and they use a two-layer model of a thin porous dust cover above an icy surface.

TL;DR: The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov-Gerasimenko, has been detecting individual dust particles of mass larger than 10−10 kg by means of the GIADA dust collector and the OSIRIS Wide Angle Camera and Narrow Angle Camera as mentioned in this paper.
