|
|
The Sun is closer to the Earth than the Moon.
|
|
|
The moon has craters, which creates more gravity.
|
|
|
The sun is too hot.
|
|
|
The sun is too far away, so it has less affect on Earth.

Detailed explanation-1: -However, the sun is 390 times further from the Earth than is the moon. Thus, its tide-generating force is reduced by 3903, or about 59 million times less than the moon. Because of these conditions, the sun’s tide-generating force is about half that of the moon (Thurman, H.V., 1994).
Detailed explanation-2: -Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
Detailed explanation-3: -The closer objects are, the greater the gravitational force is between them. Although the sun and moon both exert gravitational force on the Earth, the moon’s pull is stronger because the moon is much closer to the Earth than the sun is.
Detailed explanation-4: -The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur.
Detailed explanation-5: -In a nutshell, if the moon gets away from Earth, there will be no tides on the planet.
