Albedo variegation on Comet 67P/Churyumov-Gerasimenko
Björn J. R. Davidsson, Bonnie J. Buratti, Michael. D. Hicks
We here study the level of albedo variegation on the nucleus of Comet 67P/Churyumov-Gerasimenko. This is done by fitting the parameters of a standard photometric phase function mod…
Thermal Properties and an Improved Shape Model for Near-Earth Asteroid (162421) 2000 ET70
Sean E. Marshall, Ellen S. Howell, Christopher Magri +8
We present thermal properties and an improved shape model for potentially hazardous asteroid (162421) 2000 ET70. In addition to the radar data from 2000 ET70's apparition in 2012,…
Global Albedos of Pluto and Charon from LORRI New Horizons Observations
B. J. Buratti, J. D. Hofgartner, M. D. Hicks +14
The exploration of the Pluto-Charon system by the New Horizons spacecraft represents the first opportunity to understand the distribution of albedo and other photometric properties…
Composition of Near-Earth Asteroid 2008 EV5: Potential target for Robotic and Human Exploration
Vishnu Reddy, Lucille Le Corre, Michael Hicks +5
We observed potentially hazardous asteroid (PHA) 2008 EV5 in the visible (0.30-0.92 microns) and near-IR (0.75-2.5 microns) wavelengths to determine its surface composition. This a…
