Description
The extent and length (173 km) of Catena Sylvester starts off from the north-western rim of crater Pascal C at its southern end and right past Sylvester on its eastern side some 100 kilometres away from its rim. Two candidates initiallly stand out as possible sources for its creation -- that of the Orientale Basin to its south (~ nearly 3500 km away) and Rozhdestvenskiy crater to its north. The catena line of craters, however, are not exactly radial to these features, so the possible source may in the end be the Imbrium Basin some 2000 km to its south-east. The catena itself is made up of nearly a hundred small, overlapped craters each, roughly, 10 kilometres in diameter, amd these have merged together so much in areas both at the south-eastern and north-western ends that the feature has taken on a valley-like appearance.- JohnMoore2

Nomenclature
- Named from nearby crater. (Sylvester)
- Somewhere near Catena Sylvester (or near Sylvester itself, which is also at the moon's northern limb) should be a crater which was called Vaisala by Percy Wilkins and Patrick Moore. However, this name (Vaisala) went to a bowl-shaped craterlet on the Aristarchus-plateau, north of Aristarchus (Aristarchus A).
- Vaisala was a contemporary Finnish astronomer.
- The pronounced valley south of Sylvester and east of Froelich is unofficially called Vallis Sylvester by D. Caes. See LAC 9 in the Clementine Atlas (the upper right corner of LAC 9). Note that this valley is NOT Catena Sylvester!
