How many moons would it take to equal the mass of earth?

Answer 1

How many moons would it take to equal the mass f earth? I am going to assume you are referring the Earth's moon. This is a rather simple calculation. We simply take the mass of the Earth, and divide by the mass of the moon. We can express the formula like this.

mass of moon * number of moons = mass of Earth

therefore

mass of Earth ÷ mass of moon = number of moons

The mass of the moon is approx. 7.347 7 × 1022 kg. The mass of the Earth is 5.9736×1024 kg. Now, it is a simple matter of division, and we can get the number 81.30081 recurring, so lets just say 81.3.

Answer 2

The Sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass. The Earth's mass is 5.9736×1024 kg. The Suns mass is 1.9891 ×1030 kg. So the Sun is 332946 times the mass of the Earth. The Sun's diameter is about 100 times that of the Earth. So, you'd have to line up 109 Earth's end-to-end to stretch across the face of the Sun and it would take about 1,000,000 Earths to fill the volume of the Sun.

Answer 3

This question is really blurry. It could be three questions in one.

Here are quick answers to all three:

Regarding the apparent visual 'size' of the earth and moon:
If you were way out somewhere, say on Venus or Mars, looking out at the earth and moon in your night sky, the earth would appear to be a disk about 3.7 times as 'wide' as the disk of the moon.

Regarding the volumes of the two bodies, i.e. how much space each one occupies:
The volume of the sphere of the earth is about 49.5 times the volume of the sphere of the moon.
That means if each one were a metal shell like a globe, and the moon shell was full of water, you'd have to pour that one into the earth shell 49.5 times in order to fill up the earth shell.


Regarding the masses of the two bodies, i.e. how much rock and other stuff each one is made of:
The mass of the earth is about 82 times the mass of the moon.
That means that if you put them on opposite sides of an enormous see-saw, in a kiddie park on the surface of some even-more-enormous planet, you'd have to put 82 moons on one end of the see-saw in order to balance one earth on the other end.

Answer 4

The circumference of the Earth's moon is 6,786.03 miles and its weight is 1.6195x10^23 pounds. The circumference of Venus is 23,628 miles and the weight of Venus is 1.07306x10^25 pounds.

Answer 5

The moon is the smaller one. Its diameter is 2,159 miles, while the earth's diameter is 7,926 miles.

If the earth were hollow, it would take 49 moons to fill it.

Answer 6

The Earth has an equatorial diameter of 12756.2 km

The Moon has an equatorial diameter of 3476.28 km

Gives about 3.6695 Moons

Answer 7

The diameter of Venus is about 3.48 times the moon's diameter.

A better comparison is with the Earth. Venus' diameter is about 96% of Earth's ...

practically the same.
