* The Moon: The Moon's gravitational pull is the main driver of Earth's tides. Although the Moon is much smaller than the Sun, it is much closer to Earth, making its gravitational influence stronger.
* The Sun: The Sun's gravitational pull also plays a role in Earth's tides, although it is weaker than the Moon's. When the Sun and Moon align (during new and full moons), their gravitational forces combine, resulting in higher tides called "spring tides." When the Sun and Moon are at right angles to each other (during quarter moons), their gravitational forces counteract each other, resulting in lower tides called "neap tides."
While other celestial bodies have some gravitational influence on Earth, their effect is negligible compared to the Moon and Sun.
