1 Lecture 24: Saturn The Solar System First we focus on solar distance, average density, and mass: Planet Distance Density Mass Mercury Venus Earth Mars (asteroid) Jupiter Saturn Uranus Neptune Pluto (where we have used Earth units) Saturn s Rings 1

2 Hubble views of Saturn 2

3 The Solar System Saturn s Orbit The period of Saturn s orbit is P = 29.5 Earth years Saturn Sun a Kepler s third law relates the semi-major axis a to the orbital period P Saturn s Orbit Kepler s third law relates the semi-major axis a to the orbital period P 2 3 P a = years AU Solving for the semi-major axis a yields a P = AU years Since P = 29.5 Earth years, we obtain a = 9.54 AU Saturn s orbit has eccentricity e = /3 3

4 The distance from the Sun varies by about 10% during an orbit D perihelion = 9.01 AU D aphelion Saturn s Orbit = AU Like Mars and Jupiter, Saturn is easiest to observe during favorable opposition At this time, the Earth-Saturn distance is only about 8 AU Saturn (perihelion) Earth Sun Saturn (aphelion) Saturn s Orbit It is best to observe Saturn during favorable opposition because It displays the full phase It is at minimum distance from Earth It is at minimum distance from the Sun It has largest angular size and is brightest Saturn (perihelion) Earth Sun Saturn (aphelion) Bulk Properties of Saturn Saturn is the second largest planet in the solar system We have for the radius and mass of Saturn R saturn = 60,000 km = 9.4 R earth M saturn = 5.6 x g = 95 M earth The volume of Saturn is therefore given by V Hence V saturn = 9 x cm 3 4 = π 3 3 saturn R saturn 4

5 Bulk Properties of Saturn The average density of Saturn is therefore ρ saturn M = V saturn saturn g = cm We obtain ρ saturn = 0.62 g cm 3 Hence there is little if any iron and no dense core inside Saturn Saturn is composed mostly of hydrogen gas It has a relatively small, rocky core Saturn s Rotation Is there any way to find a single, meaningful rotation period for the entire planet? A B C The rotation period is different for clouds in bands A, B, and C Like Jupiter, Saturn displays differential rotation The strong magnetic field indicates that the rotation period of the core is about 10 hours, which is close to Jupiter s spin period The fast rotation drives powerful winds and storms Auroras on Saturn 5

6 Differential (shear) rotation drives storms on Saturn 6

7 Saturn s Rotation The rapid rotation produces a strong Coriolis force and a significant equatorial bulge However, Saturn has a spin axis tilt of 27 o, which is much larger than the 3 o tilt for Jupiter This causes somewhat different weather and band patterns on Saturn The tilt of the axis also causes us to view Saturn s rings from various angles during Saturn s orbit Jovian planets animation Saturn s Atmosphere Atmospheric composition: Jupiter s Atmosphere: H % H % He % He % CH % CH 4 -- trace NH % NH 3 -- trace H 2 O -- trace H 2 O -- trace Water ice clouds Ammonia ice clouds Water ice clouds Ammonia ice clouds Like Jupiter, Saturn was able to retain its primary atmosphere The two planets probably started out with very similar atmospheric compositions Saturn and Jupiter If Jupiter and Saturn have the same overall composition, why is Jupiter more dense? Probably because Jupiter is more massive and has a rockier core (Saturn s core contains some ice which lowers the density) ρ ρ saturn jupiter = 0.62 g cm = 1.24 g cm 3 3 7

8 Saturn s Atmosphere Why are the atmospheric compositions so different now? We need to examine the structure of Saturn s atmosphere Saturn Jupiter A earth - GM = R Surface Gravity Using values for the Earth, Moon, Jupiter, and Saturn, we obtain for the surface accelerations A jupiter - GM = R earth 2 earth jupiter 2 jupiter = 9.8ms A moon = 24.9 ms A 2 GM = R saturn 2 - GM = R moon 2 moon saturn 2 saturn = 1.7 ms 2 = 10.38ms 2 The acceleration at the cloud level on Saturn is close to that on the Earth s surface Saturn s Atmosphere Because Saturn has a lower surface gravity at the cloud level, it s cloud deck is thicker (200 km) than Jupiter s (80 km) This allows us to see the colorful, underlying layers more easily in Jupiter s atmosphere The temperature at the cloud tops on Saturn is 97 K The predicted equilibrium temperature at Saturn s distance from the Sun is 73 K Therefore, Saturn radiates about three times more energy than it receives from the Sun 8

9 Saturn s Atmosphere As with Jupiter, heating due to the radioactive decay of heavy elements is not strong enough to explain the observed temperature of Saturn Saturn is too small to have retained its heat of formation We think that Saturn is still experiencing internal differentiation as dense material sinks towards the center Saturn s atmosphere is so cold that helium can condense and rain down into the deep interior (Jupiter is too warm for this to happen) Hydrogen gas Helium droplets Helium gas Saturn s Atmosphere The ongoing differentiation causes the interior to heat up The heating occurs when kinetic energy is converted into thermal energy Energy is Released at bottom Rock at top of cliff The helium droplets fall with high speed into the interior When they bump into other droplets, it causes heating Saturn s Atmosphere The helium rain phenomenon explains: the observed depletion of helium in Saturn s atmosphere (relative to Jupiter s) the extra heat produced by Saturn Saturn s atmosphere: Jupiter s Atmosphere: H % H % He % He % CH % CH 4 -- trace NH % NH 3 -- trace H 2 O -- trace H 2 O -- trace Water ice clouds Ammonia ice clouds Water ice clouds Ammonia ice clouds 9

10 With a radius of 60,000 km and thickness of 200 km, the atmosphere is mostly molecular hydrogen gas, H 2 A huge shell of metallic hydrogen under great pressure exists below a radius of 30,000 km Farther inside lies the icy, rocky core, with a radius of about 15,000 km Interior of Saturn Saturn s interior Jupiter s interior 10

11 Saturn s Rings In 1857, James Clerk Maxwell showed that Saturn s rings cannot be solid, liquid, or gas Therefore, they must be composed of many small objects, all independently orbiting Saturn This was confirmed in 1895 when the Doppler shift of sunlight reflected from the particles was measured Saturn s Rings The albedo of the ring particles is about 0.8, suggesting an icy composition the ring particles are snowballs The thickness of the rings is only meters, while the radius is about 100,000 km the rings are VERY thin The thinness is maintained by particle-particle collisions and interactions with Saturn s moons Saturn s Rings Inside the Roche limit, the tidal force of Saturn overwhelms the self-gravity of a moon, ripping it apart The rings may exist due to the breakup of one or more small moons that passed inside Saturn s Roche limit 11

12 Saturn s Rings The structure of the rings is VERY complex. We observe: Spiral density waves Many gaps Braided rings Shepherd satellites Transient spokes 12

13 Braided F-ring Shepherd satellites movie Shepherd satellites 13

14 Saturn s Rings The numerous gaps in the rings are caused by resonances with the various satellites of Saturn For example, the Cassini division is due to a 2:1 resonance with Saturn s innermost major moon, Mimas Ring gaps 14

15 Saturn s Rings The Cassini division is in a 2:1 resonance with Mimas The outer edge of the A ring is in a 7:6 resonance with Janus The Encke gap is in a 5:3 resonance with Mimas Transient spokes Saturn s Moons Currently 46 natural satellites of Saturn have been discovered They are primarily composed of ice, most with an average density of about 1 g cm -3 The largest moon is Titan, which is 5,150 km in diameter, and has a density of 1.9 g cm -3 Titan is unique among moons in that it possesses an atmosphere The moon has a distinctly reddish color due to its atmospheric composition Saturn s moons webpage 15

18 Saturn with moon Titan Titan s Atmosphere Titan has a reddish color due to its atmospheric composition N 90% Ar 7% CH 4 3% Titan s atmosphere acts like a solar-powered chemical factory Many hydrocarbon compounds are probably present on the surface There may be methane snow and rain, and oceans of ethane Surface pressure is 60% greater than Earth s, surface temperature is 97 K (the equilibrium temperature) Is life possible there? Huygens video 1 Huygens video 2 Huygens video 3 18

19 Titan s Atmosphere Why does Titan have a dense atmosphere, when none of the other moons do? At its large distance from the Sun, Titan was much colder, and able to retain its methane and ammonia Radioactivity warmed the ices to form an atmosphere Sunlight split the ammonia (NH 3 ) into hydrogen and nitrogen, and the hydrogen escaped into space The methane remained to form the dense atmosphere we see today 19
