A peak of eternal light (PEL) is a point on a body within the Solar System which is always in sunlight. Such a peak must have high altitude, and be on a body with very small axial tilt. The existence of such peaks was first postulated by Beer and Mädler in 1837 saying with respect to the lunar polar mountains, "..many of these peaks have (with the exception of eclipses caused by the Earth) eternal sunshine". 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. PELs 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 or day of the year, and the relatively stable temperature range.
