Planet 2 is warmer than planet 1
because (N2⋅cp2) > (N1⋅cp1)
✍️ In the Figure:
Two bodies subjected to the same solar flux
The Planet Surface Rotational Warming Phenomenon
states:
Planets and moons (without atmosphere, or with a thin atmosphere) the Mean Surface Temperatures (Tmean) relate (everything else equal) as their (N*cp) products’ sixteenth root:
The Planet or Moon the Mean Surface Temperature Universal Equation (Tmean) is:

Smooth spheres and smooth surface planets and moon, specifically: Mercury, Earth, the Moon, Mars, Europa, Ganymede do not follow Lambertian cosin law because they have strong specular reflection constituents. They do not absorb the entire flux falling on their surface.
