Interpretation of Rimae Hevelius by John Moore using Lunar Orbiter images IV-162-H1, IV-168-H3, IV-169-H1 The part of the feature extending to the lower left (labeled Rima Hevelius II) that is outside Hevelius was originally regarded as a separate rille known as Riccioli I.

Rimae Hevelius

Additional Information

  • Given that Hevelius crater has an approximate diameter of 115 km, the length of Rima Hevelius I is about 196 km, II is about 138 km long, while III is about 90 km (all subject to exact measuring not taken here). Rima Hevelius II ends at crater Riccioli G in the south-west (bottom left and just of picture). - JohnMoore2


  • Named after the associated crater (Hevelius).
  • Mary Blagg's Collated List of 1913 included five rilles (catalog entries 1954-1958) associated with Hevelius.
  • The original IAU nomenclature of Blagg and Müller retained all five of these as Roman-numeraled rilles.
  • Sheet 2 of the Army Map Service's topographic map gives their interpretation of the locations of Hevelius Ir through Vr, although IVr is probably misplaced, since Neison describes and draws it as being one of two rilles intersecting on the floor of Hevelius. The remaining three rilles are placed entirely outside Hevelius, although the existence of Hevelius Ir is doubtful (and it appears not to have been seen by Schmidt).
  • The original nomenclature seems to have been abandoned by the University of Arizona in preparing its System of Lunar Craters. Quad Maps F4 and F5 introduce a completely new system of numbering featuring just three named rilles, in which the original Hevelius Vr becomes Rima Hevelius II, IVr becomes Rima Hevelius III, and the original Hevelius IIr (or IIIr?) is extended onto the floor of Hevelius as Rima Hevelius I.
  • The system of three numbered Hevelius rilles proposed in the System of Lunar Craters was also adopted on LAC 56, although it is less clear if the preparers of that map regarded the rille extending out of Hevelius to the southeast as part of the newly-designated Rima Hevelius I. Both the System of Lunar Craters and the LAC maps were approved as official representations of the then-current IAU nomenclature.
  • The designations in the System of Lunar Craters also seem to have been adopted by NASA on pages 304 and 322 of NASA SP-241 (not an official IAU publication).
  • In 1973 the IAU expressed its intention of renaming multiple rille systems, and since then the status of the Roman-numeraled desginations has been unclear, with the former systems currently being referred to in their entirety as "rimae".
  • The current nomenclature maps accompanying the IAU Planetary Gazetteer place the name Rimae Hevelius both in the center of Hevelius and over the rille formerly known as Rima Riccioli I. It is unclear from the labeling if the rille extending out of Hevelius to the southeast (through Lohrmann D), or any of the other rilles in that vicinity are regarded as part of Rimae Hevelius.
