A 2 km-size asteroid challenging the rubble-pile spin barrier - a case for cohesion
D. Polishook, N. Moskovitz, R. P. Binzel +11
The rubble pile spin barrier is an upper limit on the rotation rate of asteroids larger than ~200-300 m. Among thousands of asteroids with diameters larger than ~300 m, only a hand…
ExploreNEOs VIII: Dormant Short-Period Comets in the Near-Earth Asteroid Population
M. Mommert, A. W. Harris, M. Mueller +8
We perform a search for dormant comets, asteroidal objects of cometary origin, in the near-Earth asteroid (NEA) population based on dynamical and physical considerations. Our study…
Distribution of CO2 ice on the large moons of Uranus and evidence for compositional stratification of their near-surfaces
Richard J. Cartwright, Joshua P. Emery, Andy S. Rivkin +2
The surfaces of the large Uranian satellites are characterized by a mixture of H2O ice and a dark, potentially carbon-rich, constituent, along with CO2 ice. At the mean heliocentri…
Space-Based Thermal Infrared Studies of Asteroids
A. Mainzer, F. Usui, D. Trilling
Large-area surveys operating at mid-infrared wavelengths have proven to be a valuable means of discovering and characterizing minor planets. Through the use of radiometric models,…
