Earth has a radius of about 6,371 kilometers, Jupiter has a radius of about 69,911 kilometers, the Sun has a radius of about 696,340 kilometers, and the Solar System is vast (with the distance from the Sun to Neptune being about 4.5 billion kilometers). A city has a size (diameter) that can be on the order of tens of kilometers, which is closest in scale to the size of a neutron star.
