Sun -> Earth: 108:1 Sun -> Moon: 416:1 Earth -> Moon: 3.7:1
The moon is 1/4 the diameter of the Earth
In rough rounded figures . . . -- The moon's diameter is 27.3% the size of the Earth's diameter. -- That makes the moon's surface area 7.5% the size of Earth's surface area. -- And it makes the moon's volume 2% the size of the Earth's volume. -- The moon's mass is 1.23% the size of the Earth's mass. (When we notice that the moon has 2% of Earth's volume but only 1.23% its mass, we realize immediately that the moon's average density is only 60% of the Earth's average density.)
The escape velocity is given by √2gR Hence it's value Ve on the earth and Vm on the moon is Ve = √2ge.Re Vm = √2gm.Rm Therefore , their ratio = Ve/Vm = √ge.Re/√gm.Rm = √6 x 10 = √60 = 8 nearly
because the moon is one quarter size of the earth.
Sun -> Earth: 108:1 Sun -> Moon: 416:1 Earth -> Moon: 3.7:1
The earth/moon radius ratio is about 3.67/1 and the mass ratio is about 80/1.
Earth=1, Moon=1/6. Or, Moon=1, Earth=6
The moon is 1/4 the diameter of the Earth
Mercury is larger than the moon and so is closer in size to Earth than the moon is. It should be noted that Mercury is closer in size to the moon than it is to Earth.
Size: The Moon has about 1/4 of the diameter of Earth. Mass: The Moon has about 1/81 of the mass of Earth.
The moon is about 1/4th the size of the Earth.
Moon = 1/4 of Earth

sun, moon, and earth Lergest to smallest: Sun, Earth, moon
The moon and the planet it orbits that have the highest ratio of their masses are Earth's moon and Earth. The earth is only about 81 times as massive as its moon. In the #2 planet/moon mass ratio among the eight planets, Saturn is 4226 times as massive at Titan.
