Plato Crater and Environs (imaged 7 April 2017).

Plato is a large and very prominent mare-filled crater that lies in the northern part of the moon on the north shore of Mare Imbrium (Sea of Showers). Further north lies Mare Frigoris (Sea of Cold). A spectacular feature along the west wall of the 101-km-wide Plato crater is a 15-km-long triangular-shaped slump block which has subsided off the crater wall into the 3.83 Giga-year old crater, and which has come to rest on the solidified lava floor of the Plato crater.

Plato crater - in the 17th century - was depicted on lunar maps as Lacus Niger Major (great black lake) due to it's dark appearance as a result of the crater being filled with a 2.6 km thick sequence of solidified basalt lava. Plato's central peak (and ray system) have been buried beneath this mare basaltic volcanism which erupted both within the crater and in the surrounding mares. Basaltic lava from within the crater has locally spilled over the crater edge (east and west ends) to form two radial rille's (the most prominent being the 87-km-long Plato Rille (Rimae). The uppermost 5-10 km of this rille can just be seen here. Rille's are linear depressions caued by the erosional action of lava rivers, or are linear collapse depressions developed over drained, radial lava tubes that were conduits for lava flowing down the flanks of lava-filled impact craters.

Higher than Mt Kosciuszko, the stunning, isolated, 8000-foot-high massif of Mons Pico (note its high albedo) rears above Mare Imbrium, and can be seen just east of the equally spectacular Montes Teneriffe.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
