TL;DR: In this paper, the results of an 8-year survey carried out at the La Silla Observatory with the HARPS spectrograph to detect and characterize planets in the super-Earth and Neptune mass regime were reported.

TL;DR: In this article, the authors used stereo-photogrammetric methods (SPG) to analyze the rotational elements of 67P and derived a volume for the northern hemisphere of 9.35 km3 ± 0.1 km3.

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.
