Why does the Moon have a greater influence on Earth's tides than the Sun does?
A.
because the Moon is closer to Earth than the Sun is
B.
because the Moon is more massive than the Sun
C.
because the Moon is less massive than the Sun
D.
because the Moon is farther away from Earth than the Sun is
The Sun is much more massive than the Moon, but the Moon has a bigger influence on Earth's tides than the Sun. Why is this?
Why, if the sun is so much more massive than the moon, isn’t it responsible for the Tides? Use Universal Law of Gravitation to explain.

- Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes the moon to orbit the earth. The force of gravitational attraction is represented by the equation F=Gm1m2r2F=Gm1m2r2, where FFF is the magnitude of the gravitational attraction on either body, m1m1m_1 and m2m2m_2 are the masses of the bodies, rrr is the distance between them, and GGG is the gravitational constant. In SI units, the units of force are kg⋅m/s2kg⋅m/s2, the units of mass are kgkg, and the units of distance are mm.
