Earth and Sun from the Moon’s South Pole

This visualization shows the unusual motions of the Earth and Sun as viewed from the South Pole of the Moon. The animation compresses three months (a little over three lunar days) into two minutes. The virtual camera is on the rim of Shackleton Crater, partially visible in the bottom right, and is aimed at the Earth. The mountain on the horizon, about 85 miles away, is unofficially known as Mons Malapert.

Here, the Sun glides around the horizon, never more than 1.5 degrees above or below it, while the Earth bobs up and down, never veering far from 0° longitude. The Earth appears to be upside-down and rotating backwards. The perpetually low Sun angle produces extremely long shadows that rotate across the rugged lunar terrain.
