Description
System of rilles on the floor of [/Posidonius Posidonius]. A somewhat unusual mix of the linear rilles characteristic of [/floor%20fractured%20craters floor fractured craters] and the sinuous rilles characteristic of lava channels. - JimMosher JimMosher

Additional Information
- IAU page: Rimae Posidonius
- Based on LO-IV-086H, Rille I is about 50 km long and 1.1 km wide over most of its length, but broadening to 1.7 km wide near its middle. Rilles II, V, and VI are mostly in the range 0.8-0.9 km wide. Rille II is extremely sinuous over most of its length, but appears to include a relatively straight, but very narrow, stretch hugging the base of Posidonius inner west wall from about the 8 o'clock to the 9 o'clock position (ending at the gap in the wall). Including this 31 km long segment, and the 47 km segment at the foot of the inner north wall, its total length (not counting the tiny twists) is about 135 km. - JimMosher JimMosher
Nomenclature
- Named for the crater within which the rilles fall ([/Posidonius Posidonius]).
- Number 162 in Debra Hurwitz's Atlas and Catalog of Sinuous Rilles.
- The original IAU nomenclature of [/Blagg%20and%20M%C3%BCller Blagg and Müller] included five Roman-numeraled rilles within [/Posidonius Posidonius].
- The identifications given in the Lunar Orbiter image at the top of this page are based on the numbering in [/System%20of%20Lunar%20Craters System of Lunar Craters] maps B2 and B3 and on NASA charts LAC-26 and LAC-42. The indended identity of rilles III and IV is somewhat ambiguous. There are two rille segments near the "? IV" label, one probably an extension of V. It is unclear which the number is intended to refer to, but most probably it is the one on the left running towards Posidonius A. Similarly, there are several rilles near the "III ?" label, and it is unclear which the name was meant to refer to. - JimMosher JimMosher
- In 1973 ([/IAU%20Transactions%20XVB IAU Transactions XVB]), the IAU declared its intention to replace the Roman-numeraled rille system with something new, but to date no action has been taken on this proposal. The entire rille system is currently known as Rimae Posidonius. It is unclear if the previously-designated Roman numerals continue to be recognized are not. - JimMosher JimMosher
- The data for the position and diameter of Rimae Posidonius given in the title line of this page, and repeated from the [/IAU%20Planetary%20Gazetteer IAU Planetary Gazetteer] defines a circle entirely on the western floor of [/Posidonius Posidonius]. Classic rilles III, V, and VI, and the northern parts of II fall outside this circle. Whether this is intentional, or not, is unclear. - JimMosher JimMosher
