No. The moon's density is about 61% the density of the Earth.
Where you got the figure of "1/80th" is that the moon's mass is about 1/80th
as much as Earth's mass.
If you mean 1/80, that would refer to the Moon's mass - it is about 1/80. of the Earth's mass. The Moon's diameter, on the other hand, is about 1/4 of the Earth's diameter; this would make the Moon's volume about 1/64 (1/4 cubed) of the Earth's volume.
The moon's average density is about the same as the density of mantle of the Earth.
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's mass is 7.35 x 1022 kg, about 1.2 percent of Earth's mass. Put another way, Earth weighs 81 times more than the moon. The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60 percent of Earth's density.
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.
Compared to the Earth, the moon has roughly -- 27.3% as great a diameter -- 7.4% as much surface area -- 2% as much volume -- 1.23% as much mass ( 1/81 ) -- 60.7% of Earth's density -- 16.5% as great a gravitational acceleration on its surface
The average density of the Earth's moon is about 3.34 grams per cubic centimeter, which is roughly 60% of Earth's average density. This lower density suggests that the moon's interior composition is different from Earth's, with a lower proportion of iron and a higher proportion of lighter elements.
no it is about 1/6 the density 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 average density of the Moon is about 3.34 grams per cubic centimeter, which is roughly 60% of Earth's average density. This lower density is due to the Moon having a smaller core and less overall mass compared to Earth.
The average distance between Earth and its moon is 238,000 miles, approximately.
Yes. It has no iron core.
