Facts about Oberon's Cratering Record
- 08
Oberon's cratering record reveals that many impact basins lack well-preserved ray systems, indicating significant surface modification through gardening processes over billions of years.
- 07
Oberon's crater rims frequently display terraced scarps extending several kilometers inward, revealing the moon's layered subsurface structure beneath its ancient icy exterior.
- 06
Extensive ejecta blankets surrounding Oberon's craters indicate that impacts occurred into material with relatively low porosity, creating distinctive ray patterns visible across the moon's icy surface.
- 05
Oberon's heavily cratered surface exhibits a distinctive pattern of multi-ring impact basins, with several craters displaying central peaks and terraced walls indicating impacts into a relatively rigid icy crust.
- 04
Oberon's cratering record suggests a surface age of approximately 2 billion years based on impact density comparisons with other icy moons in the outer solar system.
- 03
Impact cratering on Oberon appears concentrated in the trailing hemisphere, suggesting the moon's orbital motion influences where debris strikes its surface.
- 02
Oberon's largest crater, Hamlet, spans approximately 206 kilometers in diameter and represents one of the most prominent impact features on the Uranian moon's surface.
- 01
Uranus's moon Oberon displays over 200 impact craters larger than 50 kilometers across its heavily cratered surface.
