- Titan is a moon of Saturn. Titan has wind erosion features. Would you expect Titan to have an atmosphere?A small cloud in Jupiter's equatorial region is observed to be at 120.80 ° west longitude in a coordinate system that rotates at the same rate as the deep interior of the planet. Another observation made exactly 9.50 Earth hours later finds the cloud at 119.60 ° west longitude. Jupiter's equatorial radius is 71,500 km. What is the observed equatorial wind speed in kilometers per hour?_____ km/s ______ hr
- What is the escape velocity from the surface of Callisto if its mass is 1.1 x 1023 kg and its radius is 2.4 × 10° km? ( Hint: Use the formula for escape 2GM velocity, V. = V r X km/sAt what average distances (in AU) from the Sun would you expect to find Kirkwood gaps where the orbital period of asteroids are respectively four-ninths, and three-sevenths, of the orbital period of Jupiter? (Hint: use Kepler's third law.) inner gap at_______ AU outer gap at_______ AUDespite being composed primarily of gas, Jupiter and Saturn have large magnetic fields. This is primarily due to the presence of _________________ beneath its cloud tops.
- Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter. The observed surface temperature is 133K, the albedo is 0.47, the solar constant is 15W/m2.1If Neptune's clouds have a temperature of 60 K, at what wavelength will they radiate the most energy?
