Aristoteles and Eudoxus.

Acquisition type: Lucky imaging

Aristoteles and Eudoxus craters are located on the Southern edge of the Luna Mare Frigoris - The Sea of Cold, which in terms of Mare descriptive Selenography is somewhat vaguely defined. Aristoteles lies east of the Montes Alpes and to the north of the Montes Caucasus which are at the foot of the image. It is an impact crater of approximately 87kms in diameter with a depth of 3700.0m. Its relatively shallow depth for a crater of such diameter may indicate post impact lava flooding. Unlike most examples of complex craters the absence of any high central mountain could be an indication that such an event did occur leaving only the tops of the impactor peaks visible. The almost complete collapse of the crater South-Western wall is sharply seen in this image along with well-defined terraces to the East bordering the earlier formed Mitchell crater. The South Wall of Aristoteles has also been “pushed in” by ejecta from the impactor that later produced Eudoxus crater.

Eudoxus crater is 67km in diameter and around 3.4km in depth, as with its neighbour it lacks a central peak and contains only a group of low hills scattered about the central area. The terraced structure of the walls is clearly visible.

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.
