Nobody would be that dastardly.
this one is 1:310^9, and it has feel-the-gravity weights for the planets, too:

what I personally found mind blowing was insight into earth at scale. if you go for 1mm==10km then earth has 4m equatorial circumference, 1.28m diameter. bat that scale, Mt Everest is .8mm, the Mariana trench is 1.1mm
and the distance from Nuremberg where I live to Erlangen "next door" is 1.6mm, and Germany is the size of my hand, and.big enough to have visible curvature.
the outer 60km, that is 6mm at this scale, are solid, then it's dough, some places even pudding or outright liquid. the crust
is* an eggshell, swimming on the inside of earth.breathable atmosphere is just a teensy thin .5mm layer, overall it's 2mm.
such a model should be in every school, to me it's a deeply humbling experience, reminding me of the fragility of our habitat.
Your brain just imagines that you see it closer/bigger when looking at it, especially if it's near the horizon/through branches/other things on the ground. This effect gets more pronounced the longer you stare at it. I think this is why it's so hard to get a picture of the moon that looks like how you see it, unless you use an impractically long lens.
Average distance from Earth to the Moon:
Approximately 384,400 kilometers.
Diameters of the other planets:
Mercury: 4,880 kilometers
Venus: 12,104 kilometers
Mars: 6,779 kilometers
Jupiter: 139,820 kilometers
Saturn: 116,460 kilometers
Uranus: 50,724 kilometers
Neptune: 49,244 kilometers
For a total of 380,011 km, so 4,000 km to spare!
So needs both max surface levels subtracted.
I had known this fact for a while, but the ending of portal 2 really solidified it in my mind.
They are much larger, but the moon is much further away from Earth than you imagined.
What happens as you pile mass into a planet is that the planet becomes dense, not large, and this is because of gravity.
Jupiter has more than twice the mass of Saturn, but is only moderately larger in diameter.
You can keep dumping mass into a planet, and it just won't get much bigger, until you have enough mass that fusion kicks off, and then suddenly the now-a-star inflates, because it becomes extremely hot and then you have something the size of the Sun.
It's more complexe than this. Yes Jupiter is twice as dense as Saturn, but so is Uranus, which is much smaller.
Also the main reason for why Jupiter is just moderately larger than Saturn is that, at equal density, mass goes as the cube of diameter. If Jupiter had a density as low as Saturn, its diameter would only be 26% higher than it is today, and just 50% bigger than Saturn despite being 3.3 times as heavy.
Do we even know what's inside the gas giants, how big is the rocky core inside (if any)? Having probes dive inside of the gas giants for exploration would be an awesome space mission!
The Galileo mission to Jupiter carried a probe which dived into the atmosphere: https://science.nasa.gov/mission/galileo-jupiter-atmospheric...
It varies between 360000km and 405000km ish https://en.wikipedia.org/wiki/Lunar_distance
https://science.nasa.gov/resource/solar-system-sizes/
The lunar distance from the Wikipedia entry is from center of earth to center of moon, so if we want to be more precise we would need to subtract the radius of both earth (6371 km) and moon (1737 km), in order to find the distance between their surfaces.
So on average we have: distance from surface of earth to the moon = average lunar distance earth radius - lunar radius = 384399 - 6371 - 1737 = 376291 km
Which means that putting all the planets side by side, starting from the surface of the earth, we could fit them but not on an average day, we’d need the moon to be a bit above the average distance :-)

The Reddit post is from 9 years ago so this checks out.
So pluto could easily fit as well

i wasn't aware of the fact, and even though after thinking about it it's kind of obvious, the visualization really helps to let the fact sink in and make it memorable.
