Gravity locks the Moon, forcing one of its faces to orient towards the Earth. Selenites inhabiting the lunar equator would see the Earth globe fixed at the zenith, slowly changing its phases as the synodic cycle progresses. Earth's phases are complementary to the Moon's; if the planet wanes, the satellite waxes; if one is full, the other is absent. When Earth's shadow is cast upon the Moon, lunarians witness a solar eclipse, while Earthlings perceive a lunar eclipse.​​

 

At the moment of totality, solar rays pass through Earth's atmosphere, enveloping the Moon in a somber reddish glow, which the Selenites perceive as a fiery ring surrounding the darkened planet. This annular twilight is the sum of every sunrise and sunset on the blue horizon, where Earthlings located in the penumbra witness, rising at dawn or setting at dusk, the Moon eclipsed by Earth's fervent shadow.​
