The Dance of the Moon, 2022

This animation from the NASA Goddard Space Flight Center shows the Moon from the Earth, including phases, librations, and change in apparent size due to the Moon’s eccentric orbit. The bar graph behind the Moon shows the Earth and Moon to scale, and the current distance between them in Earth diameters. At top left is a plot of the Moon’s orbit around the rotating Earth. The bottom left shows lunar librations in both longitude and latitude. Moon imagery is from Lunar Reconnaissance Orbiter.
