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.

Dark Is the Sun from the neck and when held up to another belonging to a potential mate will sync in pattern and color to approve marriage. Many times through Earth's existence it faced its end, but each time this event occurred, humanity was at a high point in intelligence and was able to rescue Earth from annihilation. When the sun died, they ignited the moon, and later when the moon died, the Earth was moved to safety. But now Earth's death is approaching during a time when man's technological levels are at a low point. The story opens with Deyv being forced to
