The average distance between Earth and the moon is 384,000 kilometers. The largest planet in our solar system is Jupiter with a diameter of 1,400,000 kilometers, which means that fewer than three of these planets can fit between Earth and the Moon. The truth is that Jupiter is about as big as a planet can be (diametrically speaking).
Depends on the size of the planets
The smallest planet in the solar system is mercury with a diameter of 4900 km, which means that between the Earth and the moon you can fit about 80 of these planets.
But a planet can be even smaller – 1,000 kilometers, if not less. There is such a body in our solar system – Dwarf planet Ceres, but it is located within the asteroid belt and is therefore defined by the new definition (which I think is silly) as a Dwarf planet rather than a true planet, as is Pluto. You can place up to 400 of these planets between the Earth and the Moon.
The answer is between about 2 and 400.
What Are The Diameters of the Planets?
- Mercury 4,879 kilometers
- Venus 12,104 kilometers
- Mars 6,771 kilometers
- Jupiter 139,822 kilometers
- Saturn 116,464 kilometers
- Uranus 50,724 kilometers
- Neptune 49,244 kilometers
Total: 380,008 kilometers
All the planets of the Solar System fit between the Earth and the Moon, as illustrated in the image you can find here.
What’s more, there would even be room for Pluto (if it ever regains its status as a planet).
There would also be room for Pluto, since its average diameter is 2,390 kilometers.
Despite the gigantic size of Jupiter and Saturn (alone they occupy more than half the distance) the rocky planets together do not even come close to the diameter of Neptune.
It should also be said that the calculation only works with the mean radius of the planets. With the equatorial radius, we would overshoot by about 3000 kilometers (and with the polar radius we would have even more space left over since, for example, Saturn, has an equatorial diameter of 120,000 kilometers and a polar diameter of 108,000.
