The Near-Centaur Environment: Satellites, Rings, and Debris

A. A. Sickafoose, S. M. Giuliatti Winter, R. Leiva +3

The unexpected finding of a ring system around the Centaur (10199) Chariklo opened a new window for dynamical studies and posed many questions about the formation and evolutionary…

A Contact Binary Satellite of the Asteroid (152830) Dinkinesh

Harold F. Levison, Simone Marchi, Keith S. Noll +3

Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…

A Predicted Dearth of Majority Hypervolatile Ices in Oort Cloud Comets

C. M. Lisse, G. R. Gladstone, L. A. Young +30

We present new, ice species-specific New Horizons/Alice upper gas coma production limits from the 01 Jan 2019 MU69/Arrokoth flyby of Gladstone et al. (2021) and use them to make pr…

A Near Surface Temperature Model of Arrokoth

O. M. Umurhan, W. M. Grundy, M. K. Bird +19

A near surface thermal model for Arrokoth is developed based on the recently released facet model of the body. This thermal solution takes into account Arrokoth's surface re…

Anomalous Flux in the Cosmic Optical Background Detected With New Horizons Observations

Tod R. Lauer, Marc Postman, John R. Spencer +27

We used New Horizons LORRI images to measure the optical-band () sky brightness within a high galactic-latitude field selected to have reduced diffu…
