It's a common misconception that there's a high tide on the side of Earth furthest from the sun. The sun's gravity is actually not the main cause of tides on Earth.

Tides are primarily caused by the moon's gravitational pull.

Here's why:

* The Moon's Gravitational Pull: The moon is much closer to Earth than the sun. While the sun's gravitational pull is stronger overall, the moon's pull is much stronger on the side of Earth facing the moon. This pull creates a bulge of water, resulting in high tide.

* The Earth's Rotation: As the Earth rotates, the bulge of water follows the moon, causing high tides to occur roughly every 12.5 hours.

* The Centrifugal Force: Earth's rotation also creates a centrifugal force that pushes water away from the Earth's axis. This force contributes to the bulge of water on the side of Earth opposite the moon, also causing a high tide.

The sun's gravity does play a role in tides, but it's a weaker influence. When the sun, moon, and Earth are aligned (during new and full moons), the combined gravitational forces create even higher tides called "spring tides." When the sun and moon are at right angles to each other (during quarter moons), their forces partially cancel each other out, resulting in lower tides called "neap tides."

Therefore, the high tide on the side of Earth furthest from the sun is not directly caused by the sun's gravity, but by the combined forces of the moon's gravity and Earth's rotation.
