What allows moons of Jupiter and Saturn to have liquid interiors?
The solar flux at the top of Earth's atmosphere is 1366W/m2. If Jupiter is 5.2 AU from Sun, what is the solar flux at the top of Jupiters atmosphere? Jupiter's albedo is 0.52, how does that influence its energy budget?
If Titan could be moved out to the orbit of Neptune would its atmosphere freeze into solid nitrogen? The formula to estimate the blackbody radiation temperature in Kelvin is:
where α is the albedo at 0.3, L the luminosity is 1.5 Watts/meter2, σ , the Stefan Boltzmann constant is 5.67 X10-8 W/m2/K. What would be the temperature and would the atmosphere freeze out if the freezing point of N2 gas 63 K?
answer choices
63 K, maybe
75 K, no
46 K, yes
103 K, no
