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.

Jovian–Plutonian gravitational effect 1980, Moore collaborated with Clyde Tombaugh, the man who had discovered Pluto in 1930, to publish a new book about the dwarf planet. The hoax claims that the gravitational pull of Jupiter and Pluto combined will cause one to spend a significantly longer amount of time in the air due to an increase in gravitational pull from the distant planets; however, this is incorrect. Although other planets do exert a gravitational pull on humans on Earth, the amount is very small. Although Jupiter is very massive, it is also very far away. When at its closest distance to Earth of
