if a scale of the solar system was built where 1mm equaled 1 mile, could the model be practically built in a city? yes or no
I suppose the answer would be no because that is a really small diameter is 742 billion mm
I just wanted to check with someone because this seems like a stupid question.
your supposition is correct
Yes
Ok it is correct but the other answer
No, it would not be practically feasible to build a scale model of the solar system in a city where 1mm equals 1 mile. The reason is that the diameter of the solar system is incredibly large, measuring around 742 billion millimeters (or 742 billion miles in the real-world scale). Trying to fit such a massive model in a city would be practically impossible.
To put it into perspective, if the model were to be built, the size of the Earth alone would be about 7,918 millimeters (or 7.9 meters) in diameter. The other planets, like Jupiter and Saturn, would be even larger. It would require an enormous amount of space and resources to build and display such a model.
Hence, your initial assumption is correct - building a scale model of the solar system where 1mm equals 1 mile in a city would not be realistic due to the sheer size and dimensions involved.
