Peak of eternal light

The pair said about the lunar polar mountains: "...many of these peaks have (with the exception of eclipses caused by the Earth) eternal sunshine".

[1] These polar peaks were later mentioned by Camille Flammarion in 1879, who speculated that there may exist pics de lumière éternelle at the poles of the Moon.

[3][4] The ESA SMART-1, NASA Clementine and JAXA SELENE spacecraft made maps of the lunar poles that have been used to identify sites receiving eternal light.

[3] Based on images from the Clementine lunar mission, a team from Johns Hopkins University suggested that four locations along the rim of the Peary crater are candidates for peaks of eternal light.

Further data from the SELENE spaceprobe determined that one peak at Peary Crater receives sunlight for 89% of a lunar year.

Lunar South Pole: four peaks are identified which are illuminated more than 80% of the time
