Question:

You are part of a team that discovered a new planet in our solar system and decided to call it Planet Assoca. This new planet has no atmosphere, a solar constant (S) of 1200 W/m², an albedo () of 0.55, and a radius of 5,400 km. Based on these values, answer the following questions:

Question 8: What is the temperature of this new planet? (3 marks)

Question 9: You realize that your colleague has measured the radius of the planet incorrectly and it is actually 450 km. What would happen to the temperature based on this new radius? Justify your answer

Question 10: During the winter season (which only lasts 2 Earth months) the albedo increases by 0.10 to a value of 0.65 (based on the rapid expansion of snow and ice). How much does the temperature increase or decrease? Why would this change in albedo change temperature? (3 marks) Future research indicates that Planet Assoca has a two-layer atmosphere.
