Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days.

The footprints made by astronauts on the moon will stay there for many centuries. There is no erosion on the moon to disturb the footprints.

NOTE: The moon has no weather so there is no erosion from wind, rain, rivers or the sea. There is also no geological activity to disturb the soil, like volcanoes or earthquakes. The effect of the solar wind on soil particles on the moon surface is far too slow to be significant. Meteorite strikes are the only likely sources to erase the footprints. Even a tiny fragment or speck of space rock can wipe out a single footprint.

The average density of Saturn is 0.687 g/cm3 which is less than that of water (1 g/cm or 1000kg/m3).

NOTE: This is because Saturn is made up largely of hydrogen and helium even with a (small) solid core of nickel, iron and rock (compounds of silicon and oxygen). Hydrogen and helium are mostly in liquid form. Liquid metallic hydrogen (1.15 g/cm3) surrounds the core followed by a mixture of liquid hydrogen (0.0708 g/cm3 or 70.8 kg/m3) and liquid helium (0.125 g/cm3). The outermost layer is gaseous. Saturn is the only planet in the Solar System that is less dense than water.
