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.

Solar eclipses on the Moon Solar Saros series of the Moon is the equivalent to the Lunar Saros series of the Earth. In a package of Wills's Cigarettes, one of the tobacco cards first issued in 1928 for a few years displays the solar eclipse on the Moon showing the atmospheric ring. This is considered the first depiction of a solar eclipse as seen on the Moon. Solar eclipses on the Moon Solar eclipses on the Moon are caused when the Earth passes in front of the Sun, blocking its light. Viewers on Earth will see a lunar eclipse. The solar eclipses are only seen
