The Earth's radius would be a mere 158 miles (254 km) if it was shrunk by 96%, remaining large enough to maintain its hydrostatic equilibrium.
No, it would not, because the smallest possible radius for a spherical celestial body is 200 km (124 miles) and Mercury would only have a radius of 61 miles (98 km) if it was shrunk 96%.
Mars's radius would be a measly 86.4 miles (139 km), meaning it would be unable to maintain its hydrostatic equilibrium.
Yes, Venus would be large enough to be spherical if the radius was shrunk by 96%. The point at which a planet achieves hydrostatic equilibrium is 124 miles (200 km), and Venus' radius would be 150 miles (241 km).
The radius of the moon would be 588.7 miles (947.4 km).
If the planet Venus had a moon 27% of its radius, then its moon would have a radius of 1,025 miles (1,650 km).

The radius of the moon would be 11,840 miles (19,055 km), seven times larger than any other moon in the Solar System.
The radius of this moon would be 9,862 miles (15,871 km), six times larger than any other moon in the Solar System.
The radius of this moon would be 4,170 miles (6,711 km), 2.55 times larger than any other moon in the Solar System, and about as large as Earth.
the radius of this moon would be 4,295 miles (6,912 km), 2.6 times larger than any other moon in the solar system, or slightly larger than Earth.
we can't use jupiters moons for anything because fistly we can not get out that far to reach Jupiters moon and if we could it would take thousands of years and Jupiters Moons would be to big to do anything with anyway. so the answer to What could Jupiter's moons be used for? is....Nothing.
