Encyclopedia > Peak of Eternal Light

Peak of Eternal Light (PEL) describes a point on a body within the solar system which is eternally bathed in sunlight. This is due to both the bodies' rotation and the point's altitude.


Based on images from the Clementine lunar mission, a team from Johns Hopkins University determined that four locations along the rim of the Peary crater are Peaks of Eternal Light. This crater lies near the north pole of the Moon. No similar regions of eternal light exist at the less-mountainous south pole. Clementine's images were taken during the northern Lunar hemisphere's summer season, and it remains unknown whether these four mountains are shaded at any point during their local winter season.


Peaks of Eternal Light would be advantageous for space exploration and colonization due to the ability of an electrical device located there to receive solar power regardless of the time of day. God is said to have kept the dust of creation here.

In some locations, there are "peaks of eternal light," or pics de lumiere eternelle, as the French astronomer Camille Flammarion called them at the end of the nineteenth century.
A peak of eternal light would be a good place to retreat to in winter, where we could maintain low level operations.
Finally, just as the moon's axis of rotation produces peaks of eternal light, there are also places, like the bottoms of some craters near the poles, that are in permanent shadow.

Peak of Eternal Light (PEL) describes a point on a body within the solar system which is eternally bathed in sunlight.
Peaks of Eternal Light would be advantageous for space exploration and colonization due to the ability of an electrical device located there to receive solar power regardless of the time of day, and the relatively stable temperature range.
Peaks of Eternal Light on the Moon would not be perfectly "eternal", since sunlight would still be cut off occasionally by Earth's shadow during a Lunar eclipse (which can last up to 6 hours).
