Additional Information

The Aristarchus Plateau, aka Wood's Spot

  • The upper right part of this map (the rather chaotic area north-northwest of Aristarchus and Herodotus) is the mustard-colored Aristarchus Plateau, of which its typical color was investigated by R.W.Wood (hence the area's nickname: Wood's Spot). It is the most distinct one of the moon's colored regions, and it is observable through all sorts of telescopes, especially during and after Full Moon (from Full Moon to Last Quarter Moon).- DannyCaes Nov 6, 2008 See also: Colored Regions on the Moon, Part 1

Aristarchus vs Tsiolkowsky

  • At 20° North/ 51°30' West (about 150 kilometers southwest of Aristarchus) is the antipode of Tsiolkowsky's central peak. This is a rather curious fact! To know that the "brightest" crater on the moon's near side (Aristarchus) and the "darkest" crater on the moon's far side (Tsiolkowsky) are almost exact antipodes of each other!- DannyCaes Nov 20, 2008

The Pear (Bessarion B)

  • Bessarion B, the odd pear-shaped formation of two craters connected by a straight elevated line. This connection must look very impressive on the location, especially for astronauts walking on the straight elevation. Imagine: a crater at left, a crater at right, and in the middle some sort of four kilometer long bridge. - DannyCaes Nov 18, 2015.
  • A similar formation is the couple Fontenelle C and Fontenelle F on Chart 3 (the same sort of straight elevated line between the two craters). - DannyCaes Nov 18, 2015
