Textbook Question
Chapter 11, Problem 25EAP
Suppose someone claimed la make the discoivries described below. (These are not real discoivries.) Decide whether each discovery should be amsulrnii mtsmuible or surprising. More than one right answer may be possible, so explain your answer clearly.
- Saturn’s core is pockmarked with impact craters and dotted with volcanoes erupting lava.
- Neptune's deep blue color is not due to methane, as previously though!, but instead is due to its surface being covered with an ocean of liquid water.
- A jovian plane! in another star system has a moon as big as Mars.
- A planet orbiting another star is made primarily of hydrogen and helium and has approximately the same mass as Jupiter but is the same size as Neptune.
- A previously unknown moon orbtts Jupiter outside the orbits of other known moons. It is the smallest of Jupiter's moons but has several large, active volcanoes.
- A previously unknown moon orbits Neptune in the planet’s equatorial plane and in the same direcnon that Neptune rotates, but it is made almost entirely ol metals such as iron and nickel.
- An icy, medium-size moon orbits a jovian planet in a star system that is only a few hundred million years old. The moon shows evidence of active tectonics.
- A jovian planet is discovered in a star system that is much older than our solar system. The planet has no moons but has a system of rings as spectacular as the rings of Saturn.
- Future observations discover rainfall of liquid water on Titan.
- During a future mission to Uranus, scientists discover that it is orbited by another 20 previously unknown moons.

If Earth-based telescopes can resolve angles down to 0.25 arcsec, how large could a trans-Neptunian object be at Pluto’s average distance from the Sun and still not present a resolvable disk?
If Neptune's clouds have a temperature of 60 K, at what wavelength will they radiate the most energy? (Wein's Law)
If you took all the matter in Saturn’s rings and packed it into a sphere withan average density of 1.2 g/cm3, what would the radius of the sphere be? How does thatcompare to the radius of Mimas, for example? How about the case of Uranus: what wouldthe radius of the sphere composed of all ring mass be? (Again use a density of 1.2 g/cm3)
According to Wikipedia, the lower estimate for the mass of Saturn’s rings is 3 × 1019 kgand the mass of Uranus’s rings is ∼ 2 × 1016 kg.
