Cassini (Martian crater)
crater on Mars

Cassini is a crater on Mars named in honor of the Italian astronomer Giovanni Cassini. The name was approved in 1973, by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature.
The crater measures approximately 415 kilometers in diameter and can be found at 327.9°W and 23.4°N. It is in the Arabia quadrangle of Mars. Pictures of small craters on the floor of Cassini reveal multiple layers. Some of these layers can be easily seen in the pictures below. Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers.
A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars.
Recent research leads scientists to believe that some of the craters in Arabia may have held huge lakes.
This brief starts where responsible research should: with the source description of “Cassini (Martian crater)” as crater on Mars. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as crater on Mars. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 6, 2026. The linked authority identifier is Q1305288. Authority coordinates are 23.350, 32.110. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1973.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
