All the gas giants; in our Solar System, Saturn has the lowest density (less than the density of water).
Mars is the least dense of the rocky planets.
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.
Gasses have the lowest density.
The phrase "least dense planet" refers simply to the planet with the lowest density, which is the planet's mass divided by its volume. In our solar system, Saturn is the least dense planet with a density of roughly 0.7 (water, by comparison, has a density of 1, or 1 gram per cubic centimeter). This is attributed to its large outer envelope of gas - although it is thought to have a denser rocky core.
