Problem on Orbit cycle

Calculate the hot and cold temperature after 25 orbits. Assume a 100kg spherical spacecraft made of aluminum. Assume that the spacecraft is in an equatorial orbit. How is calculation 1 different for a spacecraft in a 90 degree (polar) orbit?

The average temperature first lowers and then its increased. Each orbit cycle adds the temperature of 3.75 degree centigrade.  25 orbit simulation causes 25 degree .

The hot temperature goes to  65 degree centigrade.

Generally temperature varies from -71 to 51 degree.

In case of polar orbits The average temperature is increased. Each orbit cycle adds the temperature of 4.25  degree centigrade. 25 orbit simulation causes 42  degree.

The hot temperature goes to 87 degree centigrade.
