Tidal force the Moon produces a greater tidal force on the Earth than the Sun, even though the Sun exerts a greater gravitational attraction on the Earth than the Moon, because the gradient is less. The Moon produces a greater tidal force on the Earth, than the tidal force of the Earth on the Moon. The distance is the same, but the diameter of the Earth is greater than the diameter of the Moon, resulting in a greater tidal force. What matters is not the total gravitational attraction on a body, but the difference from one side to the other. The greater
Wall of the Sun and Wall of the Moon Wall of the Sun and Wall of the Moon The Wall of the Sun and Wall of the Moon are a pair of murals made of ceramics and designed by the Catalan artist Joan Miró for the UNESCO building in Paris.
