Wall,Michael Janssen,Randolph L. Kirk,Rosaly M. C. Lopes,Flora Paganelli,Jani Radebaugh,Lauren Wye,Y. Anderson,Matthew A. Allison,R. Boehmer,Philip S. Callahan,Pierre Encrenaz,E. Flamini,G.

Vetrella,Robert West +37 more
TL;DR: These northern-hemisphere lakes constitute the strongest evidence yet that a condensable-liquid hydrological cycle is active in Titan’s surface and atmosphere, in which the lakes are filled through rainfall and/or intersection with the subsurface ‘liquid methane’ table.
Journal ArticleDOI

TL;DR: The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds.
Journal ArticleDOI
Binary asteroids in the near-Earth object population.
Jean-Luc Margot,Michael C. Nolan,Lance A. M. Benner,Steven J. Ostro,Raymond F. Jurgens,Jon D. Giorgini,M. A. Slade,Donald B. Campbell +7 more
TL;DR: This system and other binary near-Earth asteroids have spheroidal primaries spinning near the breakup point for strengthless bodies, suggesting that the binaries formed by spin-up and fission, probably as a result of tidal disruption during close planetary encounters, may be binary systems.
Journal ArticleDOI
Radar Imaging of Binary Near-Earth Asteroid (66391) 1999 KW4
Steven J. Ostro,Jean-Luc Margot,Lance A. M. Benner,Jon D. Giorgini,Daniel J. Scheeres,Eugene G. Fahnestock,Stephen B. Broschart,Julie Bellerose,Michael C. Nolan,Christopher Magri,Petr Pravec,P. Scheirich,Randy Rose,Raymond F. Jurgens,Eric De Jong,S. Suzuki +15 more
TL;DR: High-resolution radar images reveal near-Earth asteroid (66391) 1999 KW4 to be a binary system that is dominated by an equatorial ridge at the object's potential-energy minimum and has exotic physical and dynamical properties.
Journal ArticleDOI
Orbits Close to Asteroid 4769 Castalia
TL;DR: In this paper, the authors used a radar-derived physical model of 4769 Castalia (1989 PB) to investigate close orbit dynamics around that kilometer-sized, uniformly rotating asteroid.
