Earth-based radar view by Campbell et al.: Cabeus is the large, somewhat irregular depression filling most of the frame. When the librations are favorable, the Moon's north pole can tip towards Earth by more than 7°. Hence radar waves transmitted from Earth can illuminate more of Cabeus' floor than can sunlight, which never shines from more than 1½° north of the Moon's equator. Note: in the LPOD image from which this has been cropped, the Earth-based radar data was re-mapped to a north-up aerial view, that is, the Earthward direction (from which the radar waves emanate) is to the top. The circular crater to the left of center, near the bottom of this view, has been named Ibn Bajja.

• Apollo 15's B-and-W Hasselblad frame AS15-95-12988 could be the only Apollo photograph on which the lunar south pole's immediate environs are seen. The crater Malapert is visible near the central part of the frame's upper margin. The south pole itself must be "touching" the upper margin (or perhaps a little bit beyond the margin).
• A High-Resolution scan of this frame (of AS15-95-12988) is needed! On the Hi-Res scan of it, we should get the answer to the question if Cabeus is also visible in it.

Description

(IAU Directions) CABEUS.--Another object out of the range of satisfactory scrutiny. Madler considered that it is as deep as Newton. According to Neison, a central peak and two craters can be seen within under favourable conditions. Schmidt draws a long row of great depressions on the N. side of it.

Nomenclature

• Named for Niccolò Cabeo (February 26, 1586 – June 30, 1650), an Italian Jesuit philosopher. He is noted for his contributions to physics experiments and observations. Cabeo's second publication was a commentary on Aristotle's Meteorology. In this work, he carefully examined a number of ideas proposed by Galileo Galilei, including the motion of the earth and the law of falling bodies. Cabeo was opposed to Galileo's theories. Cabeo also discussed the theory of water flow proposed by Galileo's student, Benedetto Castelli.
• The name Cabeus was introduced by Riccioli. Whitaker (p. 211) believes the crater labeled by Riccioli is the modern Newton, but since only a single crater is drawn in an area occupied by many, it is difficult to say. - JimMosher JimMosher
• In her Collated List Mary Blagg reported the name Cabaeus in use for the present feature (Catalog Number 3319) by Beer and Mädler and by Neison, 1876. She also found the name used by Julius Schmidt, but was uncertain what feature he intended to use the name for, since Schmidt's crater appeared to be farther to the east.
• According to a report by Arthur in IAU Transactions XIIB, Franz used the name Cabeus for the crater currently known as Drygalski.
• The name Cabaeus (for the present feature) was part of the original IAU nomenclature of Named Lunar Formations.
• The spelling was "corrected" to Cabeus in Table III of Kuiper's Photographic Atlas, where Cabaeus is said to be an "error by Blagg."
• John Westfall proposed calling Cabeus B, at 82.4° south/ 53.0° west, Bonestell (see: the south pole map on page 67 of the article Exploring the Moon's South Pole, by Alan M. MacRobert). Chesley Bonestell was one of the most important pioneers of Space Art, and was also one of the contributors to the legendary illustrated spaceflight articles by Wernher von Braun and Willy Ley in Collier's magazine. Westfall's suggestion was not adopted by the IAU, however Bonestell is honored by an IAU-named crater on Mars. - DannyCaes DannyCaes Apr 12, 2008
