North pole of the Moon
A peak of eternal light on the North Pole?
Well, there are no peaks on the Moon, as the mountains have gentle slopes , as we know.
The Sun is 31 arc minutes large but the Moon's axis is tilted 1.5 degrees relative to the ecliptic plan, so I'm quite sure there is no place on the Moon where the Sun shines 100% of the time.
