Saturn’s moon Titan has shorelines that appear to be shaped by waves

The liquid hydrocarbon waves would likely reach a height of a meter.

During its T85 Titan flyby on July 24, 2012, the Cassini spacecraft registered an unexpectedly bright reflection on the surface of the lake Kivu Lacus. Its Visual and Infrared Mapping Spectrometer (VIMS) data was interpreted as a roughness on the methane-ethane lake, which could have been a sign of mudflats, surfacing bubbles, or waves. Advertisement Palermo’s simulations showed that wave erosion resulted in coastline shapes closely matching those actually observed on Titan.
