How big are the craters of the moon?
This is a question often heard by amateur astronomers during public demonstrations, which is not easy to answer.
Of course we can refer to the catalogs of lunar geography or the internet to give an order of magnitude, but these are numbers, without real assimilation with the incredible dimensions of these structures
40 kilometers for 320 so for another.
To give an idea of the size of the craters of the moon, I have “glued” some earthly cities at the bottom of a crater; I chose the most typical, not the biggest, or the smallest. It is a crater relatively felt in the history of the moon: 800 million years.
The crater is 93 km in diameter and 3800 m deep
Copernic situation :
If we text the crater with satellite photos of the different Earth cities, the impressive dimension of the impact makes sense
Here Paris intramuros is placed in the center. Greater Paris occupies less than 50% of the surface of the crater. The new towns of Cergy-Pontoise, Montigny the Bretonneux its on the “terraces”. Mantes la Jolie in the west, Meru in the North Coulommiers in the East and Dammarie The Lys in the South mark the edge of the chasm.
