Description

The outer limit of the Moon's surface potentially observable from a given site. If the Moon were uniformly illuminated, the limb would form a complete circle, but a bumpy one (due to the topography). In practice, a substantial part of the limb (about half) is usually in shadow ("beyond" the terminator), and hence not readily observable. Nonethless the presence of the limb at these locations is made apparent when the Moon moves over ("occults") a more distant celestial object. - JimMosher JimMosher

Additional Information

  • See also: Saber's Beads (a curious optical phenomenon related to the very young and extremely thin moon's crescent, or the very old (immediately after and/or before New Moon). - DannyCaes DannyCaes Feb 12, 2008


LPOD Articles

(mostly photographs and drawings made during favourable libration)

  • This "around the Moon's orb" list is an overview of Limb/ Librations-related LPODs, arranged in a "clockwise" fashion; running from the moon's North pole to the North-Eastern limb, the Eastern limb, the South-Eastern limb, the South pole, the South-Western limb, the Western limb, the North-Western limb, and finally to the North pole again.
    • List compiled by Danny Caes.

Out on a Gaussian Limb (the telescopic visibility of farside crater Joliot during favourable libration).
Enhanced LPOD Out on a Gaussian Limb.

The Mare Marginis region

Beyond the Cat's Smile ("Lacus Risus Felis" and Mare Marginis during favourable libration). The unknown "crater" is just a portion of highland inmediately east of Dreyer ; Dreyer C sits on top of it - Nunki Nunki May 18, 2011

The Mare Smythii region

What's New? (Mare Smythii during favourable libration).
Out on a Limb (the Mare Smythii region during favourable libration, local sunset terminator).

The Humboldt region

Petavian View (Humboldt and limb during favourable libration).
Magnificent Side View (Humboldt and limb during favourable libration).
Howard's Atlas (the Humboldt region and limb during favourable libration).
On the Limb again (the Humboldt region during favourable libration).

The southeastern limb region

The Hausen region

A bigger Copernicus (Hausen during very favourable libration).

Reply: yes, Pierazzo is observable; check this LPOD, the ray crater is visible almost at the limb, following the line that joins southern rims of Kepler and Reiner (see also discussion page) - Nunki Nunki May 29, 2011
Leaks (the dark-halo crater at 9° North/ 90° West, near farside crater Sundman. This dark-halo crater is perhaps observable during favourable libration). See also LAC 55 and LAC 72 in B.Bussey's and P.Spudis's Clementine Atlas.
