The diameter of the Earth is roughly how many times larger than the diameter of the Moon?

Answer 1

-- The earth's diameter (distance through the center) is about 3.7 times the moon's diameter.

-- The earth's surface area is about 13.5 times the moon's surface area.

-- The earth's volume is about 49.5 times the moon's volume.

-- The earth's mass is about 82 times the moon's mass.

Answer 2

it is actually 265 to be exact (but most scientists round it to 321).

"Radius" of moon's orbit, approximately 240,000 miles.

Radius of Earth, approximately 4000 miles.

Giving a ratio of approximately 60, not 265 or 321.

Answer 3

You just need to divide the diameter of Earth by that of the Moon. If you really want this as an equation, you can write something like:E=fM

where E = diameter of Earth, f = the factor (how many times larger), M = diameter of Moon.

Answer 4

The Earth and the Moon are both nearly spherical (the shape of a Basketball).

The best estimates of their diameters are 12,756 and 3,476 kilometers respectively.

The distance from one side of the Moon to the other, straight through the center, is

about the same as the distance from Washington DC to Kamloops BC, or Spokane WA,

or Yuma AZ, or Port of Spain, Trinidad (as the crow flies).

This means that . . .

-- the Moon's diameter (the distance straight through the center) is about 27% (one quarter)

the size of the Earth's diameter;

-- the Moon's surface area ... the amount of 'land' on it ... is about 7% ( 1/15 ) as much as the Earth's;

-- the Moon's volume ... the amount of space it fills ... is about 2% ( 1/50 ) as much as the Earth's.

Those are the Moon's physical dimensions. The Moon's mass ... the amount of material

it's made of ... is about 1.2% as much as the Earth's mass.

Answer 5

The Earth is much larger than the Moon. But it is interesting to note that of all the major planets with moons, the earth is the one whose moon is the largest in proportion to its host planet.

Answer 6

Short Answer: They're the same.

Long Answer: I assume you mean the orbit time about the Sun, in this case it's misleading to say the Moon orbits the Sun, it orbits the Earth, which orbits the Sun. Hence the Moon orbits the Sun at the same rate as the Earth and so it's orbit is also 365 days.

You could argue it'd differ slightly as the Moon may begin and end at different points of it's orbit of the Earth and hence would take fractionally longer to travel the full distance, but it's safe to say this distance is negligible.

FYI: the Moon takes ~28 days to complete one orbit of the Earth.

Answer 7

The Earth at it's Equator is 40,075 km.

The moons orbit is about 1,209,480 km.

So the moons orbit is about 30 times the circumference at the equator.

If we're comparing circumferences, the moon's orbital circumference is more like 2,400,000 km, and the ratio is about 60.

Answer 8

The diameter of the Earth is roughly 3.7 times larger than the diameter of the Moon.

Answer 9

The Moon's diameter is about 1/4 of Earth's diameter.

Answer 10

i just happen to know it exactly. it is 12,756 kilometers or 7,926 miles.
