To determine which planet would have the lowest uncompressed density, we can analyze the general properties of the planets listed.

Understanding Planetary Densities

1. Gas Giants vs. Terrestrial Planets:

   • Gas giants (Jupiter and Saturn) typically have lower densities because they are composed mostly of hydrogen and helium.
   • Terrestrial planets (Mercury, Venus, Earth, Mars) have higher densities due to their rock and metal compositions.

2. Density Comparison:

   • Mercury: Highest density among terrestrial planets (about 5.4 g/cm³).
   • Venus: Similar density to Earth (about 5.2 g/cm³).
   • Earth: Average density (about 5.5 g/cm³).
   • Mars: Lower density compared to Earth (about 3.9 g/cm³).
   • Jupiter: Lower than terrestrial planets but higher than expected for a gas giant (about 1.3 g/cm³).
   • Saturn: Lowest density among gas giants (about 0.7 g/cm³). In fact, it’s so low that it would float in water if a sufficiently large body of water could be found.

Conclusion

In conclusion, Saturn, being a gas giant with a predominantly gaseous composition and low overall density, would have the lowest uncompressed density compared to all the other planets listed.

Final Answer

Saturn has the lowest uncompressed density among the planets provided.
