In this telescopic view, Hipparchus is the large crater at left, with the pronounced crater Horrocks on its floor.
Note also the curved "row of four" just above Hipparchus (craters Halley, Hind, Hipparchus C, Hipparchus L).

Lunar Orbiter 5 captured a curious bunch of dome-like hillocks on the floor of Hipparchus, as seen in Frames 098, 099, 100, and 101.
Lunar Orbiter 3 captured interesting close-ups of Hipparchus' floor, as seen in Frames 108, 109, 110 (the curious dome-like hillocks), and 111 ('Hipparchus N).

(IAU Directions) HIPPARCHUS.--Except under a low sun, this immense walled-plain is by no means so striking an object as a glance at its representation on a chart of the moon would lead one to expect; for the border, in nearly every part of it, bears unmistakable evidence of wreck and ruin, its continuity being interrupted by depressions, transverse valleys, and gaps, and it nowhere attains a great altitude. This imperfect enclosure extends 97 miles from N. to S., and about 88 miles from W. to E., and in shape approximates to that of a rhombus with curved sides. One of the most prominent bright craters on its border is Hipparchus G, on the E. Another, of about the same size, is Hipparchus E, on the N. of Horrocks. On the W. there is a moderately bright crater, Hipparchus F; and S. of this, on the same side, two others, K and I. The interior is crossed by many ridges, and near the centre includes the relics of a low ring, traversed by a narrow rill-like valley. Schmidt shows a cleft running from F across the floor to the S. border.

[A valuable monograph of Hipparchus, by Mr. E.B. Birt, was published in 1870.]

The diameter of this curious "lunar asterism" is about the same as crater Agrippa. - DannyCaes DannyCaes Nov 18, 2007
  • Hipparchus C is the brightest and most distinct example of the "eyes"-effect during Full Moon. This kind of craters (such as Hipparchus C, Hipparchus G, Pickering, etc.) look like "staring eyes" when they are observed through common telescopes. A most curious effect! Observed by Danny Caes.
  • Hipparchus C is perhaps the only crater which could be a good candidate to observe the weak illumination on its shadowed inner slopes. This remarkable effect is noticeable on several of Apollo 16's orbital Fairchild Mapping/Metric photographs. Research: Danny Caes.
  • Hipparchus contains a number of small hills and ridges, none of which exceed 1km in height Sekiguchi, 1972- fatastronomer fatastronomer


Nomenclature

  • Hipparchus (ca. 190 BC – ca. 120 BC) was a Greek astronomer, geographer, and mathematician of the Hellenistic period. He is known to have been a working astronomer at least from 147 BC to 127 BC. Hipparchus is considered the greatest astronomical observer and, by some, the greatest overall astronomer of antiquity.
  • In the days of M.F.Van Langren (Langrenus) the northern crater which is officially known as Scoresby was called Hypparchi (see page 196 in E.A.Whitaker's Mapping and Naming the Moon).
  • Bright Eye (Danny Caes's nickname for Hipparchus C, which is the brightest example of the many "staring eyes" on the Full Moon's disc).
  • For some unexplainable reason, this name (HIPPARCHUS) is still printed as "HIPPARCUS" (without "H") on LAC 77 (page 155) in the REVISED AND UPDATED EDITION of the Clementine Atlas of the Moon (2012, CAMBRIDGE UNIVERSITY PRESS). - DannyCaes DannyCaes Jan 6, 2013
  • Mentioned as HIPPARCHOS in Hergé's Tintin adventure Explorers on the Moon. - DannyCaes DannyCaes Jan 31, 2015
