Mars is the fourth planet from the Sun and the second$-$smallest planet in

the solar system after Mercury. It has a diameter of ~ $6800$ km $($about $(1)/(2)$ the earth$$s$)$

and its average distance from the sun is $230$ million km$$s $($the earth$$s average is $150$

million km$$s$).$ Can you configure a realistic combination of albedo and atmospheric

absorption properties that could make the surface temperature of Mars approximately

the same as earth$$s
