- 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?Examine the photos of Jupiter and Saturn in Figure 15. What do you notice about their shape? Referring to Figure 16 how can this peculiar shape be explained?If you visited a planet in another solar system and discovered that it was heavily cratered, but its small moon was nearly crater free, why would that be a surprise? Speculate about what might have happened to those objects.
- 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/sWhy is Mars red?Despite 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.Assume that a planet will have lost its initial atmosphere by the present time if the average molecular speed exceeds one-sixth of the escape speed. What would Mercury's mass have to be in order for it to still have a nitrogen atmosphere? The molecular weight of nitrogen is 28.If Neptune's clouds have a temperature of 60 K, at what wavelength will they radiate the most energy?
