Recent Gravity Models as a Result of the Lunar Prospector Mission
The lunar gravity field is determined from the tracking data of previous missions to the Moon with the 1998–1999 Lunar Prospector (LP) mission being the major contributor. LP provided the firstExpand

A homogeneous nucleus for comet 67P/Churyumov–Gerasimenko from its gravity field
Cometary nuclei consist mostly of dust and water ice. Previous observations have found nuclei to be low-density and highly porous bodies, but have only moderately constrained the range of allowedExpand
