However, rayed craters smaller than 500 m in diameter exist in Oxia Planum (e.g.: 18°20′30″N, 24°6′0″W) and there are possibilities for these craters to be included in further studies of the area at a smaller scale.

WebThe ejecta blanket of the Chicxulub crater was identified on the southeastern Yucatán Peninsula at distances of 3.0–5.0 crater radii from the impact center. Abundance of glide planes within the ejecta and particle abrasion both rise with crater distance, which implies a ground-hugging, erosive, and cohesive secondary ejecta flow.

WebFeb 11, 2024 · A prominent example of a rayed crater with abundant secondary craters is the large, 86-km-diameter, fresh Tycho crater situated in the nearside lunar highlands. The extensive system of bright rays contains dense clusters of secondary craters. A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter of their originating crater, and are often accompanied by small secondary … See more The physical nature of lunar rays has historically been a subject of speculation. Early hypotheses suggested that they were deposits of salt from evaporated water. Later they were thought to be deposits of volcanic ash or … See more • List of craters with ray systems • Reiner Gamma See more WebMar 21, 2012 · This image of a dark-rayed impact crater and several dark spots was obtained by NASA's Dawn spacecraft.
