• Homework:
– Rocket designs due tomorrow
– Last Homework Packet (LHP) due Monday
• Warm Up:
– Get ready for a peek at the Inner Planets!
Solar System
The Inner Planets
Mercury
• Almost no
atmosphere,
so it’s
surface
temperatures
are extreme
• Core is ¾
iron
• Small, rocky planet
• Many craters
Venus
• Thick layer
of hot
clouds of
poisonous
gas
• Clouds trap heat
• Clouds reflect
sunlight, making
it bright
Earth
• Solid and rock
• ¾ of surface
covered with
water and ice
• Thin layer of air
around it
Mars
• Rocky
planet
covered with
red, dusty
soil, due to
iron
• Thin atmosphere
made mostly of
carbon dioxide
• Polar ice caps of dry
ice and frozen water
• Extinct volcanoes
This image shows
the south polar cap
of Mars as it appears
near its minimum
size of about 400
kilometers (249
miles). It consists
mainly of frozen
carbon dioxide. This
carbon dioxide cap
never melts
completely. The ice
appears reddish due
to dust that has been
incorporated into the
cap.
This image is an
oblique view of
the north polar
cap of Mars.
Unlike the south
polar cap, the
north polar cap
probably consists
of water-ice.
Asteroid Belt
• Region that contains
small solar system
bodies
Closing it up…..
• Tell your shoulder partner two facts about
one of the Inner Planets.

• Homework:
– Rocket designs due RIGHT NOW – please
turn them in.
– Last Homework Packet (LHP) due Monday
• Warm Up:
– Get ready for a peek at the Outer Planets!
Solar System
The Outer Planets (Gas Giants)
Jupiter
• Gas planet –
made mostly
of hydrogen,
helium and
other gases
• Largest
planet
This gives you an idea of relative
sizes in our Solar System….
This true color mosaic of
Jupiter was constructed
from images taken by the
narrow angle camera
onboard NASA's Cassini
spacecraft on December
29, 2000. It is the most
detailed global color
portrait of Jupiter ever
produced. The mosaic is
composed of 27 images:
nine images were required
to cover the entire planet in
a tic-tac-toe pattern
• Has
powerful
lightning
storms
Jupiter has 63 moons
and a very faint ring
Auroras on Jupiter
Saturn
• Has the most rings, which are made of rock, dust and
ice
• Least dense planet in the Solar System (would float in
water)
Surface of Saturn similar
to Jupiter. High speed
winds and storms.
The Great White Spot,
Dec 5, 2010. Saturn
experiences storms every
few years. Storm
encompasses an area
that’s about 8x’s the
surface area of Earth
The Great White Spot,
Feb. 25, 2011. The
storm now has a tail
that has wrapped
around the planet.
The Cassini spacecraft captured this
natural color view of Saturn almost a
month after the planet's August 2009
equinox. The shadow cast on the
planet by the rings remains narrow.
Mimas can be seen as a speck at
lower left.
The shadow of Saturn's
largest moon darkens a
huge portion of the gas
giant planet. Titan (5,150
km, or 3,200 mi across) is
not pictured here, but its
shadow is elongated
across Saturn's upper
atmosphere.
On December 25, 2009, Cassini was on
the dark side of Saturn and took this
image looking toward the moon
Enceladus, seen at top, beyond the
planet and its rings. Light passing
through Saturn's atmosphere creates the
bright arc seen from the top to the
bottom of the image. At bottom center,
the light passing through is blocked by
shadows from the rings
The moon Prometheus creates an
intricate pattern of perturbation in
Saturn's F ring while the moon
Prometheus can be seen between
the thin F ring and the A ring in
the middle left of the image.
Another view of Enceladus' southern ice plumes, seen on November 21, 2009.
The moon's cryovolcanic activity was first discovered by Cassini in 2005, and
continues to be a focus of research. Primarily made up of water vapor, the plumes
also contain trace amounts of nitrogen, methane, carbon dioxide, propane, ethane,
and acetylene
Enceladus continues to spew ice into space, seen by Cassini on October 14, 2009
An aurora, shining high above the northern part of Saturn,
moves from the night side to the day side of the planet in
this movie recorded by Cassini. These observations,
taken over four days, represent the first visible-light video
of Saturn's auroras. They show tall auroral curtains,
rapidly changing over time when viewed at the limb, or
edge, of the planet's northern hemisphere. The sequence
of images also reveals that Saturn's auroral curtains
reach heights of more than 1,200 km (746 mi) above the
planet's limb. These are the tallest known "northern
lights" in the solar system. Each image was obtained with
a two- or three-minute exposure, taken in visible light
with the Cassini spacecraft's narrow-angle camera from
October 5th to 8th 2009.
Uranus
• Gas planet
• Methane gas
gives it its
blue-green
color
Neptune
• Like Jupiter
and Saturn,
Neptune
gives off
more energy
that it
receives from
the Sun
This mosaic combines an
almost true-color picture of
Neptune taken by the
Hubble Space Telescope's
(HST) Wide Field Planetary
Camera (WFPC), with a
picture of Triton taken with
the HST's Faint Object
Camera. Although faint, the
image of Triton vaguely
shows a brighter equatorial
region. The south pole is to
the lower left
This image shows bands of sunlit cirrus-like clouds in
Neptune's northern hemisphere. These clouds cast
shadows on the blue cloud deck below. The white streaky
clouds are from 48 to 160 kilometers wide and extend for
thousands of miles.
These two 591-second exposures of the rings of Neptune were taken by Voyager 2
on August 26, 1989. The two main rings are clearly visible and appear complete
over the region imaged. Also visible in this image is the inner faint ring at about, and
the faint band which extends roughly halfway between the two bright rings. The
bright glare in the center is due to over-exposure of the crescent of Neptune.
Numerous bright stars are evident in the background. Both rings are continuous.

one of the Gas Giants.
