The moon
The sole natural satellite of Earth is the Moon. It is the fifth-biggest satellite in the solar system and the largest and most massive in relation to its parent planet, with a diameter that is around one-fourth that of Earth. Its size exceeds that of the Solar System's other known dwarf planets.
According to the geophysical definitions of the term, the Moon qualifies as a satellite planet because it is a planetary-mass object with a distinct rocky body. There isn't much of an atmosphere, hydrosphere, or magnetic field there. Jupiter's moon has a surface gravity of 0.1654 g, or about one-sixth that of Earth. The Solar System's sole satellite with a higher surface gravity and density is Low.
Tidal forces are produced as a result of a slightly stronger gravitational attraction on the sides of Earth, the Moon, and the Sun that are closest to one another. The most noticeable effect of this is ocean tides, but tidal forces also have a significant impact on other Earth mechanics, the Moon, and their system.
Over a period of 27 days, the lunar solid crust experiences tides with an amplitude of around 10 cm (4 in), consisting of three components: a fixed tide caused by Earth because of their synchronous rotation, a variable tidal caused by the eccentricity and inclination of their orbits, and a small fluctuating component from the Sun.[165] Changes in liberation and distance caused by the Earth's rotation give birth to the Earth-induced variable component.
The average distance that the Moon travels around Earth was 384,400 km, or around 30 times the diameter of Earth. Its gravitational pull is the primary cause of the tides on Earth and gradually lengthens the day. The sidereal duration of the Moon's orbit around Earth is 27.3 days. The percentage of the Moon's Earth-facing surface lit by the Sun fluctuates from zero to about 100% throughout each synoptic period of 29.5 days, resulting in lunar phases that serve as the foundation for lunar calendar months. The Moon is tidally locked to Earth, which means that the near side of the Moon always faces Earth for the duration of a full revolution of the Moon on its own axis.
Although the ocean tides are significantly altered by other factors, if the Earth were a water world, it would create a tide of only one meter, which would be fairly predictable.

Therefore, the timing of the tides at the majority of locations on Earth is a result of observations that are incidentally explained by theory.
The Earth's rotation is torqued when the tidal peaks of ocean and solid-body tides are delayed. This "drains" rotational kinetic energy and angular momentum from the Earth's rotation, slowing it down.
POSITION OF MOON :
The lunar phase, or more precisely its orbital position, and the time of year, or more precisely the orientation of the Earth's axis, affect the Moon's highest altitude at culmination. For each hemisphere, the full moon is at its highest point in the sky during winter and at its lowest point during summer, with the dark moon being in between.
