Can you think of an experience in your own life, or in
someone else’s, where something that you observed turned
out to be very different from what you thought it was?
What does that experience suggest about the mindset a
scientist must have to deal with new data and observations?

PRESENTATION

1. Jupiter

a. Jupiter as Seen From Earth and From Space

(1) Jupiter is the Solar System’s largest planet.

(2) Jupiter has 318 times the mass of Earth.
Jupiter’s diameter is about 11 times that of
Earth. And so its volume is 1,400 times that of
Earth.

(3) It takes Jupiter nearly 12 Earth years to cycle
around the Sun. But it spins around on its axis
once every nine hours, 55 minutes.

b. Jupiter’s Rotation

(1) Jupiter has light- and dark-colored bands
parallel to its equator. The bands near the
equator move slightly faster than those around
the poles.

(2) The phenomenon of different parts of a planet
having different periods of rotation is known as
differential rotation. It indicates that Jupiter’s
visible surface isn’t solid. It must be partially
fluid.

Lesson Three, The Outer Planets

179
Chapter Three, The Sun and the Solar System

(3) Another thing to notice about the planet: It’s
somewhat oblate, or flattened at the poles. This
is an effect of Jupiter’s swift rotation.

c. The Composition of Jupiter’s Atmosphere

(1) The Galileo spacecraft found Jupiter’s
atmosphere to be about 90 percent hydrogen and
10 percent helium, with small amounts of
methane, ammonia and water vapor. Galileo
also found small amounts of certain heavier
elements – carbon, nitrogen and sulfur.

(2) Jupiter may have helium rain “showers” in its
upper atmosphere, with neon dissolving in
helium raindrops under certain conditions.

(3) The spacecraft’s probe found that three so-
called “noble” gases – argon, krypton and xenon
– are two to three times as prevalent on Jupiter
as in the Sun. The only way for Jupiter to get
such quantities of these gases would be to trap
them by condensation or freezing.

(4) A protoplanet is a hypothetical whirling
gaseous mass within a giant cloud of gas and
dust that rotates around a sun and becomes a
planet. New data, however, suggest that the
material that makes up Jupiter must have come
from a much colder place than Jupiter’s current
location.

d. Jupiter’s Three Groups of Moons

(1) As of 2009, the family of Jupiter’s known
moons numbers 63. The first four orbit very
close to Jupiter. They are called fragmented
moonlets.

(2) The second group is the four Galilean satellites:
Io, Europa, Ganymede, and Callisto. They are
about the same size as Earth’s Moon. Their
orbits are nearly perfect circles.

(3) The third group consists of the remaining 55
moons. Many of these orbit clockwise, unlike

Lesson Three, The Outer Planets

180
Chapter Three, The Sun and the Solar System

most objects in the Solar System, and their
orbits are fairly eccentric. Astronomers
speculate that these moons are captured
asteroids.

2. Saturn

a. The astronomer Galileo first observed Saturn in
1610.

(1) He didn’t know what to make of the “bumps” he
saw on either side of Saturn.

(2) Some 50 years later the Dutch physicist and
astronomer Christian Huygens recognized that
the “ears” on Saturn were really rings.

b. Saturn’s Size, Mass, and Density

(1) Saturn is not much smaller in diameter than
Jupiter. But it’s only half as dense. It has only
0.7 the density of water.

(2) Saturn likely has a less dense core and less
liquid metallic hydrogen than Jupiter does.

(3) Saturn’s atmosphere is like that of Jupiter and
the Sun: about 96 percent hydrogen, 3 percent
helium, and 1 percent heavier materials.

c. Saturn’s Speed of Rotation and Solar Orbit

(1) Saturn takes 29.5 Earth years to orbit the Sun. It
rotates on its axis in 10 hours, 39 minutes.

(2) Saturn is also oblate, more so than any other
planet. This is because it doesn’t have enough
gravitational force to keep a more-spherical
shape.

(3) Saturn’s rings are in the plane of its equator, and
the planet tilts 27 degrees with respect to its
orbital plane.

(4) So as both Earth and Saturn orbit the Sun,
earthlings will sometimes see the edge of

Lesson Three, The Outer Planets

181
Chapter Three, The Sun and the Solar System

Saturn’s rings, and at other points during
Saturn’s orbit they will observe the rings’ “top”
and “underside.”

d. Titan, Saturn’s Largest Moon

(1) Titan is the largest of Saturn’s more than 60
moons.

(2) It’s second largest in the Solar System, after
Ganymede, Jupiter’s largest moon.

(3) Data from the Huygens probe suggest that at
one point, Titan had an atmosphere five times as
dense as it is today. That implies that Titan is
losing material from the top of its atmosphere
into space.

e. The Particles That Form Saturn’s Rings

(1) The rings are made up of chunks of water ice
and smaller bits of rock and organic matter.

(2) There’s a lot of empty space between the chunks
too.

3. Uranus

a. What Led Herschel to Discover the Planet Uranus

(1) Herschel noticed that this object did not appear
as a point of light, as stars do.

(2) Over the period of a few nights, it moved. That
suggested a different kind of celestial object,
one evidently much closer to Earth than anyone

(3) Herschel realized he had discovered a new
planet; it was the first discovery of a new planet
in recorded history.

b. The Motion of Uranus and the Tilt of Its Equatorial
Plane

(1) Uranus takes 84 Earth years to orbit the Sun.

Lesson Three, The Outer Planets

182
Chapter Three, The Sun and the Solar System

(2) What’s unique about Uranus: It’s axis is tilted
90 degrees to its orbital plane. It spins on its
side.

(3) Because of its tilt, the poles on Uranus alternate
between 42 years of sunlight and 42 years of
darkness.

c. How Uranus’s Moons Act as Shepherds for the
Particles of Its Ring

(1) It wasn’t until 1977 that scientists made the first
reliable determination of Uranus’s diameter.
They used an occultation – the passing of one
astronomical object in front of another – to do
this. It revealed that the planet has five rings;
these rings are narrow, with well-defined edges.

(2) According to Kepler’s law, the inner moon will
orbit faster than the ring’s particles. As it passes
individual particles it pulls them along, giving
them an energy boost. This tends to push them
away from the planet, making them orbit it
slightly farther away.

(3) Similarly, particles passing the outer moon are
slowed somewhat while doing so. This tends to
make them move closer to the planet.

4. Neptune

a. What Made Scientists Search for Neptune

(1) Uranus wasn’t behaving quite the way Newton’s
laws predicted.

(2) Most astronomers thought another planet was
somehow disturbing Uranus’s orbit.

b. Neptune’s Wind Speeds and Differential Rotation

(1) Neptune experiences differential rotation – to an
extreme degree. Near the equator, it rotates in
18 hours, but near the poles, its rotation takes

Lesson Three, The Outer Planets

183
Chapter Three, The Sun and the Solar System

(2) Neptune’s magnetic field rotates every 16 hours
and seven minutes, so scientists consider this
period the basic “day” on Neptune.

(3) Voyager 2 images revealed a Great Dark Spot
on Neptune’s surface; like Jupiter’s Great Red
Spot, it was as big as Earth, was essentially a
storm system, and had extremely high-speed
winds.

(4) Neptune shows signs of much stronger weather
patterns than Uranus. Hubble’s observations of
strong winds and storm systems suggest that
Neptune has an annual cycle of seasons.

c. The Unusual Orbits of Neptune’s Two Major
Moons

(1) Triton, the largest moon, and the seventh-largest
in the Solar System, revolves clockwise around
its planet.

(2) Nereid, the other major moon of Neptune,
revolves in the “correct” direction –
counterclockwise. But it has the most eccentric
orbit of any known moon in the Solar System.
This means that its distance from Neptune
varies widely over the course of its orbit.
