What is a cold rocly sphere with no water or atmosphere?

A cold rocky sphere with no water or atmosphere is typically a description of a celestial body like a barren planet or moon. Such an object would have a solid surface composed of rock and minerals, but without the presence of liquid water or an atmosphere, it would lack conditions necessary for life as we know it. The cold temperature suggests it is far from its star or lacks geothermal activity. Examples include bodies like Mercury or certain moons of the outer planets.
