Enki Catena
catena on Ganymede
Enki Catena (formerly called Sais Facula) is a crater chain on Ganymede measuring 161.3 kilometres (100.2 mi) long.
It is composed of thirteen individual craters that are overlapping each other, forming a line or chain.
Naming
Enki Catena is named after Enki, the god of fresh water and wisdom in Mesopotamian mythology who rules over the Apsu or underground water aquifers of the world. He was the god who rescued mankind from the great flood that destroyed the world, and his wisdom also rescued Innana from the underworld. This name is in line with the rule set by the International Astronomical Union (IAU) that surface features and craters on Ganymede should be named after deities, heroes and places from Ancient Middle Eastern mythologies, which include Mesopotamian mythology.
The IAU approved the name for Enki Catena in 1997.
Geography
Enki Catena is located along the boundary between the dark region called Perrine Regio, and the brighter grooved-terrain called Sicyon Sulcus.
This chain of thirteen craters was probably formed by a comet that was torn into pieces by Jupiter's gravity as it passed too close to the planet. Soon after this breakup, the thirteen fragments crashed onto Ganymede in rapid successions. The lack of walls, scarps or division between each individual craters strongly indicates that the impacts formed almost simultaneously.

Why this record matters
“Enki Catena” is worth following because a concise public description often conceals a longer documentary argument. Here, Enki, Catena and catena provides the most credible route into that argument.
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 Jul 15, 2026. The linked authority identifier is Q5379032. Authority coordinates are 38.840, 13.860. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1997.
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.
