okay so i was given this graph and questions and have no clue where to start! any help or tips would be great! thanks! if you can't really see the graph i have attached the actual paper with the graph so u can see it!
Planet M (kg) R (km) a A (AU) MStar (kg) SStar P0(bar) T0(K)
Coruscant 6 x 10'25 17400 0.1 0.44 5 x 1029 1600 1.9 295
Dagobah 1.2 x 10'24 3500 0.05 3.3 6 x 1031 1100 1.1 315
Hoth 3.5 x 10'24 9500 0.8 4.6 2 x 1030 900 0.6 168
Tatooine 6 x 10'23 2400 0.1 0.75 5 x 1030 2900 0.5 328
Yavin IV 8 x 10'25 19000 0.3 0.01 6 x 1028 1700 0.85 290
. The columns are M for mass of the planet, R for radius of the planet, a for albedo of the planet, A for distance of the planet from the parent star, MStar for mass of the parent star, SStar for Solar Flux of the star at the planet (in W/m2), P0 for pressure at the planet’s surface, and T0 for average temperature at the planet’s surface. Tatooine is technically a double-star system, but we can consider the planet to orbit around the center of mass of the two stars.
What are the densities of these planets?
What do these imply about these planets compositions?
What are their surface gravities?
How much would you weigh on these planets?
What are the periods of these planets around their parent star (or gas giant, in the case of Yavin IV) in Earth years?
With the pressure and temperature shown, determine if the planet could have abundant liquid water.
Determine if the planet has a greenhouse effect. What should the temperature of the planet be without the Greenhouse effect? What might this imply about the composition of the planetary atmospheres?
