Gravity of Earth or (). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. Gravity does not normally include the gravitational pull of the Moon and Sun, which are accounted for in terms of tidal effects. It is a vector (physics) quantity, whose direction coincides with a plumb bob. A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface.

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
