Yes, the Earth does exhibit phases as seen from the Moon, just like the Moon exhibits phases as seen from Earth. The phases of the Earth as observed from the Moon are a result of the relative positions of the Sun, Earth, and Moon.
From the Moon's perspective, the Earth goes through a complete cycle of phases, including full, crescent, half, and gibbous phases. The phases are determined by the amount of sunlight falling on the Earth and the portion of the illuminated hemisphere that is visible from the Moon.
During a "full Earth" phase, when the Moon is between the Earth and the Sun, the entire illuminated side of the Earth is visible from the Moon, appearing as a full disk. This is somewhat analogous to the full moon phase as seen from Earth.
During a "crescent Earth" phase, when the Earth is between the Moon and the Sun, only a small portion of the Earth is visible from the Moon, creating a crescent shape. Similarly, a "half Earth" phase would resemble a half-moon phase as seen from Earth.
The exact appearance of the Earth's phases as seen from the Moon would depend on the observer's location on the Moon and the angle between the Sun, Earth, and Moon. The phases of the Earth as seen from the Moon can be a fascinating sight and are one of the unique experiences that lunar astronauts have described during their missions.
