The Moon

# How are the size and mass of the moon different from that of Earth?

The moon is smaller than the Earth so that would mean the size is smaller and the mass is also smaller because the mass depends on the size of the object so the moon would have less mass than 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 mass on the moon and the earth is the same but the weight changes.

The diameter of the Moon is 3,474 km and the diameter of the Earth is 12,742 km. This makes the Moon approximately 27% the size of the Earth. The mass of the Moon is 7.347 x 1022 kg and the mass of the Earth is 5.97x 1024 kg. The mass of the Moon is only 1.2% of the mass of the Earth.

Earth's diameter about 7925 miles. Moon's diameter about 2160 miles. The diameter of the Moon is 3,474 km and the diameter of the Earth is 12,742 km. This makes the Moon approximately 27% the size of the Earth. The mass of the Moon is 7.347 x 1022 kg and the mass of the Earth is 5.97x 1024 kg. The mass of the Moon is only 1.2% of the mass of the Earth.

The moon is not half the size of the earth. the earth has a mass of 3.98 X 1024 kg, and the moon only has a mass of 7.34 X 1022 kg, which is only about 0.012300 Earth masses.

The volume of the Moon is 2% compared to the Earth. You would need 81 objects with the mass of the Moon to match the mass of the Earth.

Earth has more mass, hence-more gravity. The Moon is 1/6th the size so has about 1/6th of ours.

In size and mass it is enormous compared to it's parent planet - The Earth.

The gravity on the moon is a lot lower than that on Earth, around 1/6th of the strength. This is down to the smaller mass of the moon, the smaller size and the lower mass of the moon means that its gravitational field is lower. An objects gravitational field strength is related to its overall mass.

Gravity is directly related to mass. A planet with a smaller mass than that of Earth would have less gravity, a planet more massive than Earth would have a stronger force of gravity. The moon is 1/6 the size of Earth, therefore the moon has 1/6 the force of gravity as Earth.

The moon is 27.3% Earth's radius, 2% Earth's volume, and 1.2% Earth's mass.

the moon is very smaller than the earth because,if the moon was the size of earth it would be hard for living things to be on earth from the moon being in the way all the time and it would be too cold at night.

The moon is smaller than the Earth. Its diameter is just over one quarter that of Earths, but its total mass is only around 1.23% of Earths mass.

Earth and Venus are similer because of there size and mass

Earth`s mass is 5,973,700,000,000,000,000,000,000kg. Pluto`s mass is 13,000,000,000,000,000,000,000kg. That makes Pluto equal to 0.0066 Earths or .66 % the size of the Earth. For a size comparison, Pluto is about one-fifth the size of our moon. See the related link for more information.

The moon is approximately 27% of the size of Earth

No. The diameter of the Moon is a little more than 25 percent of Earth's diameter, and its mass is only 1.2 percent of Earth's mass.

Because your weight depends on the mass and size of the astronomical body you're standing on. The moon's mass is about 1/80 as much as the Earth's, and its diameter is about 1/4 the size of the Earth's. The weight of anything on the moon is about 1/6 of the weight of the same thing when it's on the Earth.

Modern thought has it that a body about the size of Mars, and given the name of Theia, collided gently with the Earth, and the debris from the collision resulted in the formation of the Moon.Thus much of its rocks are similar to those of Earth, but it is mineral deficient. Earth's core was likely not involved in the collision.The Moon obviously has an uneven distribution of mass, and that is why the Moon presents one face to Earth all the time. It probably had significant spin at some time, but tidal drag with the Earth has canceled this out.1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)

The moon is about 1/4th the size of the Earth.

The Moon is considerably smaller than the Earth. Its volume is about 2% of the Earth's. Its mass is only about 1.2% of the Earth's. Its surface gravity is about 1/6 that of the Earth.
