Description


Description: Elger

(IAU Directions) HALLEY.--A ring-plain, 21 miles in diameter, on the S.E. border of Hipparchus, with a bright wall, rising at one point on the W. to a height of 7500 feet above the floor, which is depressed about 4000 feet below the surface. Two craterlets on the floor, one discovered by Birt on Rutherfurd's photogram of 1865, and the other by Gaudibert, raised a suspicion of recent lunar activity within this ring. A magnificent valley, shown in part by Schmidt as a crater-row, runs from the S. of Halley to the E. side of Albategnius.

Trivia:

  • AS12-51-7501, an orbital Hasselblad photograph of crater Halley and environs (made through one of the small windows of Apollo 12's CSM Yankee Clipper) is the only Apollo-photograph which shows the complete Lunar Module (L.M. Intrepid) surrounded by lunar background, instead of black space.
  • A medium-resolution version of this photograph shows LM Intrepid "below" the lunar horizon. There's also a King-Size Hi-Res version of this photograph, online in Kipp Teague's PROJECT APOLLO ARCHIVE. - DannyCaes Dec 6, 2007


Nomenclature

  • Named for Edmond Halley FRS (November 8, 1656 – January 14, 1742), an English astronomer, geophysicist, mathematician, meteorologist, and physicist. One problem that attracted his attention was the proof of Kepler's laws of planetary motion. In August 1684 he went to Cambridge to discuss this with Isaac Newton, only to find that Newton had solved the problem but published nothing. Halley convinced him to write the Principia Mathematica Philosophiae Naturalis (1687), which was published at Halley's expense.
  • According to Whitaker (p. 221), this name was introduced by Birt and Lee. The name Halleyius had been used earlier by Hell, but for a different formation (p. 93).
