Relative angular positions of the earth, sun, and moon

View from over the North pole with angles correct but body sizes and distances not representational.

The solar gravitational force on the Earth is on average 179 times stronger than the lunar, but because the Sun is on average 389 times farther from the Earth, its field gradient is weaker. The solar tidal force is 46% as large as the lunar.

Venus has the largest effect of the other planets, at 0.000113 times the solar effect.
