- Depth data from Kurt Fisher database
- Pike, 1976: 2.5 km
- Mare area of 353,400 km^2 according to measurements by Jim Whitford-Stark.
- The south-southeastern part of Mare Serenitatis (at Rimae Plinius and Dorsum Nicol) is depicted on the cover of the album APOLLO: ATMOSPHERES AND SOUNDTRACKS by Brian Eno, Daniel Lanois, and Roger Eno (1982). This orbital handheld Hasselblad photograph (AS17-150-23069) looks great on the L.P.-edition which appeared in the early eighties!

- Two of the Apollo Project's orbital Fairchild Camera photographs of Mare Serenitatis are included in the book FULL MOON by Michael Light and Andrew Chaikin (plates 35 and 36). These photographs are: AS17-M-0452 (plate 35) and AS17-M-0454 (plate 36). D.Caes research.

The IAU feature name means "Sea of Serenity".
- Named Regio Magna Occidentalis (Large Western Region) in pre-telescopic sketch map by William Gilbert in ~1600 - Name also included most other eastern maria! [Whitaker: Mapping and Naming the Moon, p 15]
- The impact basin is named after the mare.
The Bessel Ray (the first named example of this kind of high-albedo rays?)
The 21st Century Atlas of the Moon (Charles A. Wood/ Maurice J.S. Collins) is perhaps the very first lunar atlas which has a name for the mysterious high-albedo ray running across Mare Serenitatis and crater Bessel. This ray is one of the most stubborn riddles in the history of moon observing and selenography. What is the source of this remarkable singular ray of ejecta? Is Bessel the source? Or is it a crater to the north of Mare Serenitatis? Or perhaps to the south? It's very strange that this kind of pronounced rays (ejecta rays from impact craters) don't have official IAU names. Anyway, Chart 11 (page 35) in the 21st Century Atlas of the Moon shows the informal name Bessel Ray just north of crater Bessel. How many (ancient or recent) moonbooks have a description of the mysterious Bessel Ray in Mare Serenitatis?
