Less
Less than. The moon rock density is greater in ferromagnesion and nickel content, with greater density, whereas silicate rocks contain largely quartz and feldspar minerals.
Saturn's density is so low that it can even float on water, it has the less density in all solar objects.

An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.
greater density items wood tend to sink, they are heavier then items of less density with same displacement size
An object's density must be less than the density of water,in order for the object to float.
Density is a measure of how much mass is contained in a given volume. Objects will float if their density is less than the density of the fluid they are in and sink if their density is greater. For example, a ship floats because its density is less than that of water, while a rock sinks because its density is greater.
The more mass can be packed into a given volume, the greater the density. Alternatively, the less volume into which a given mass is packed, the greater the density.
Assuming they are floating on water, the density of the substance would be LESS than 1.
'Cold' air will have less volume so the density is greater.
It will float in water, and in any other fluid whose density is greater than the object's density.
