The Dark Side
The Moon only shows one face to the Earth


Although the Moon used to rotate in the sky compared to our point of view, it has been slowing down billions of years. And at some point in the distant past it just stopped turning from our perspective. The Earth’s gravity holds the Moon in orbit, but it pulls differently at various parts of the Moon. Over a long period, gravity slowed down the Moon’s rotation so that it finally stopped, and always displayed one face to the Earth. A similar situation has happened with most of the large moons in the Solar System. In fact, in the case of Pluto and Charon, but objects are tidally locked to each other, so they present only one face to the other.

    Our moon does have a name and so does our sun. They are Luna and Sol.
