Definition
Lunar Eclipse Phases involve the Earth casting its umbral and penumbral shadows on the Moon. As the Moon enters the Earth's penumbra, it gradually darkens, sometimes turning red due to atmospheric scattering. This phenomenon allows observers to study the relative sizes of the Earth and Moon based on the shape of the Earth's shadow on the Moon, as demonstrated by ancient Greek astronomers.
