Additional Information
The railroad at the southwestern part of the rim of Petavius
- I can't imagine it's a totally new discovery, this railroad-like feature on the southwestern part of the rim of Petavius. What is it? It seems to start just east of Wrottesley (the crater which is touching the west-northwestern part of the rim of Petavius) and it runs all the way to the southeast through the bowl-shaped crater Petavius C, and... much further across the unimpressive craters Hase and Hase D, until it meets Rimae Hase (or... are the railroad and Rimae Hase perhaps one and the same feature?). - DannyCaes Jan 7, 2016
Nomenclature
- Named for the crater (Petavius) within which the rilles are found.
- The current status of lunar rille names in the IAU nomenclature is very unclear since the IAU never followed through on its 1973 promise to give rille systems "new and more appropriate designations." Instead, the IAU Planetary Gazetteer has so-far only lumped the old Roman-numeraled rilles together as "Rimae". In the present case, the original IAU nomenclature of Blagg and Müller (1935), had only a single rille: Elger's "great cleft", labeled "I" in the illustration above. The System of Lunar Craters added "II" and "III"; although the preparers of LAC 98 (also approved by the IAU), labeled "III", but combined "I" and "II" into a single Rima Petavius. The System of Lunar Craters also draws the rille paralleling the west rim of Petavius as a sort of huge T-shaped extension of "I", but it is not clear from the drawing if it was meant to be included in the name. - JimMosher
