Orbit of the Moon the Moon's orbit around Earth, its relative timing varies greatly. In some places on Earth, there is only one high tide per day, whereas others such as Southampton have four, though this is somewhat rare. The notional tidal bulges are carried ahead of the Earth–Moon orientation by the continents as a result of Earth's rotation. The eccentric mass of each bulge exerts a small amount of gravitational attraction on the Moon, with the bulge on the side of Earth closest to the Moon pulling in a direction slightly forward along the Moon's orbit (because Earth's rotation has carried the bulge
Partial eclipses on the Moon Partial eclipses on the Moon Partial solar eclipses on the Moon are caused when the Earth passes nearly in front of the Sun, blocking a part of its light. Viewers on Earth will see a penumbral lunar eclipse. During its eclipses, the Earth will be in new phase, completely dark, except for moonshine and sunlight refracted through the earth's atmosphere, visible as a ring of light. Unlike the Earth's which shows slightly darker shadows at 50% obscuration and mostly dark at over 75% obscuration, the Moon's penumbral shadow on the surface shows light yellow at the start and the end
