Exam 10: Worlds of Gas and Liquid the Giant Planets

You observe Neptune as it occults a background star when the relative velocity between Neptune and the Earth is 30 km/s, and the star crosses through the middle of the planet and disappears for 27.6 minutes. What is Neptune's diameter?

Which of these things happens because of rain droplets falling through the atmosphere of gas giant planets?

What causes the large magnetic fields of Uranus and Neptune? How does this source help explain why the axis of their magnetic fields are misaligned and significantly offset from their rotational axes?

What causes the horizontal bands on Jupiter and Saturn to have different colors? How can they be used to probe different altitudes in their atmospheres?

Jupiter emits a large amount of radio emission because:

Which of the giant planets was discovered by accident by William Herschel?

A planet will have bands in its atmosphere like Jupiter and Saturn if:

If we measure the spectrum of radiation coming from different clouds in Jupiter's atmosphere, and we find that a cloud that appears white in visible light emits the largest number of photons at a wavelength of 3 *10 ^{- 5} m, while a cloud that appears brown in visible light emits the largest number of photons at a wavelength of 1.9*10 ^{- 5} m, how do the temperatures of the clouds compare?

If convection on Jupiter got weaker, what would happen to the storms in the upper atmosphere?

If you were to fly to Jupiter from the Earth, which of these parts of Jupiter would you hit first?

Which of these observations would allow you to measure the mass of a planet?

Why are winds on the giant planets far faster than those on Earth?
