Description
Neison, 1876 (p. 182) describes Palus Nebularum as “a level plain without any natural boundary on the south and east.” In place of a natural boundary, he suggests it should be regarded as extending to an imaginary line drawn from Theaetetus to Aristillus and from there to Mons Piton and then to Cassini Eta, a peak to the NW of Cassini (at the top of the extract from his map). Presumably Neison regarded it as including all the mare area to the north and east of Cassini, but he is not clear about that.
Additional Information
Nomenclature
- "Marsh of Mists"
- The name "Palus Nebularum" appears in Mary Blagg's Collated List (1913), where it was used by all three of her authorities, and it was part of the original IAU nomenclature of Blagg and Müller (1935). The name was deleted by Kuiper et al., whose changes to Blagg and Müller (published in the Photographic Lunar Atlas) were approved by the IAU in 1961.
- Despite the IAU approval, the name can be found on some post-1961 maps, such as the one in Baldwin (1963).
- This backwater of Mare Imbrium does not presently have a separate name. - Jim Mosher
