Collaborated by Ash Bell, Catherine Bond, Charlie Miles, Olivia McMillan, Paige Harrington and Phil Rodis of Swinburne University of Technology, 2014.

2. INTRODUCTION
The words solar system refer to the sun and all of the objects that travel
around it -- planets, natural satellites such as the moon, asteroid belt,
comets, and meteoroids. The sun, the center of our solar system, holds
eight planets and countless smaller objects in its orbit. (NASA 2014)
The Solar System (NASA 2014)

3. Description
The Earth is the third planet from the Sun and is the only known planet
to have life. Of all the planets in the solar system, the earth is the
densest. (May, 1988)
(Imgur, 2014)

4. Water
The planet Earth is predominantly water, with 70% of its surface
covered in water. This water from the ocean makes up 97% of the
worlds total water storage. (Noaa.gov, 2014)
(Hdwallpapers.in, 2014)

5. Human Population
There are currently 7.2 billion humans living on earth. The population
rate of growth is currently at 1.14%, at it’s highest point, the population
was growing at a rate of 2%, this was in the late 1960’s.
China is the most heavily populated country on earth, followed closely
by India.
(China-mike.com, 2014)

6. Interesting Fact
At the southern tip of the earth there are vast glaciers, which stretch
over 14 kilometres. This area controls the weather patterns across the
Earth, and is known as Antarctica. (Arcticantarcticcollection.com,2014)
(Imgur, 2014)

7. Saturn
(Stock Free Images 2014)
Description
Saturn, commonly known as the planet with the rings is the 6th planet
from the sun and is made up of gas predominantly hydrogen and helium.
Saturn is the second largest planet in the solar system and has a mass
95 times greater than our planet earth. (NASA 2014)

8. Enhanced view of Saturn’s rings
(NASA 2014)
Rings
Saturn has always been famous for
is dynamic and intriguing ring
system, which was first discovered
through a telescope in 1610 by
Galileo Galilei. (Cain 2013)
Saturn has a ring system composed of several bands with several
divisions between them [NASA 2014]. Saturn’s rings are mostly made up
of icy particles and are the biggest and densest compared to the rings of
other planets. (Hadhazy 2011)

9. The night side of Titan, obtained by
Voyager 2
(NASA 2014)
Moons
Titan is Saturn’s largest moon and
is the second largest moon in the
solar system.
The sheer size of this enormous
moon actually disrupts the orbits
of its neighbouring moons (NASA
2014).

10. Interesting facts
It has been discovered that the some of the conditions on
Saturn’s moons are similar to conditions on Earth (NASA
2014).
The age of Saturn’s rings is unknown. Is possible the rings
have been around for 4.54 billion years although some parts
of the rings appear as young as 100 million years old (Cain
2013).

11. Description
Planet Mars is the fourth planet
from the Sun and the second
smallest planet in the Solar
System.
The iron oxide on its surface
gives it a reddish appearance.
(NASA, 2001)
Mars’ surface features are
reminiscent of the Moon,
volcanoes, valleys, deserts, and
polar ice caps of Earth. (Yeager,
2008)
Inside Planet Mars (Space.com 2012)

12. How big is Mars?
Mars has a diameter at the
equator of 4,221 miles
(6,792 kilometres), which is
only slightly more than half
the size of Earth's.
Mars's lower density makes
the planet only about a 10th
as massive as Earth.
(Britannica, 2014)
Mars Earth Comparison (Rhorning 2012)

13. Moons
Mars has two moons,
Phobos (means “fear”) and
Deimos (means “terror”),
and they are small and
rocky.
Both moons are so small
that their gravity is too
weak to pull them into
spherical
shapes.(Britannia 2014)

Reconnaissance 2009

14. Interesting Facts
Because of its closeness to the
sun, Mars has the most violent
dust storms out of any planet on
the solar system.
The pressure is so low on Mars
that any human would literally
boil to death instantly.

15. Description
Jupiter, the largest most massive planet in our solar system, is the 6th
planet from the Sun (NASA, 2014). It is a gas giant, made up of mostly
hydrogen and helium – similar to the Sun (NASA, 2014).
Jupiter Globe
(NASA, 2011)

16. Moons
Galilean Family Portrait
(NASA, 2011)
Jupiter has 50 moons and 17 yet to be
confirmed. (NASA, 2014)
The 4 largest moons are Ganymede,
Europa and Callisto. Galileo Galilei
discovered them in 1610 (NASA, 2014).
Ganymede, the largest moon in our
solar system, is the only known moon to
have a magnetic field. (Choi, C., 2010)

17. Appearance
Jupiter’s Violent Storms
(NASA, 1979)
Colourful cloud bands and spots of
reds, pinks and oranges cover
Jupiter’s surface (Choi, C., 2010).
Jupiter’s Great Red Spot is a violent
storm nearly 3 times the size of
Earth that has been raging for more
than 300 years (NASA, 2014).
Jupiter has 3 faint rings, which were
discovered by NASA’s Voyager 1
spacecraft in 1979 (Choi, C., 2010).

18. Interesting facts
Jupiter Portrait
(NASA, 2000)
Jupiter is the fastest spinning
planet in our solar system, with 1
day on Jupiter taking just 10
hours (NASA, 2014).
The pressure at Jupiter’s core has
compressed hydrogen gas to
liquid, giving Jupiter the largest
ocean in the solar system (NASA,
2014).

19. VENUS
Venus is the second planet from the Sun and the sixth largest.
It's orbit is the mot circular of that of any planet. Venus gets its
name from the Goddess of love and beauty. It has been viewed
since prehistoric times and is one of the brightest objects in the
sky, apart from the sun and moon.

20. Size
Of all the terrestrial planets, Venus has the densest atmosphere of
all and it is composed of carbon dioxide, because of the fact that it
has no carbon cycle to help put the carbon back into its rocks and
surface features. Venus is only slightly smaller than earth, being
12,103.6 km in diameter and it's mass of 4.869e24 kg.

21. Landing
More than 20 spacecraft's have landed on Venus. The first being
the Mariner 2 in 1962. The Venera 9 landed in 1975 and was the
first spacecraft to return the first photographs of the surface.

22. Interesting Facts
It is referred to as the morning
start and evening star, being the
brightest of all planets.
There are strong (350 mph)
winds at the cloud tops but winds
at the surface are very slow, no
more than a few kilometres per
hour. (Britannica, 2014)

23. Description
Pluto was discovered by American Astronomer Clyde W. Tombaugh
in 1930. Pluto was identified as the 9th planet from the Sun and was
also the smallest.
Space Telescope Science Institute, Graphics Dept

24. Climate
Pluto has and extremely cold climate with temperatures ranging from
375 to 400 below zero.
Gravity
The gravity on Pluto is approximately one fifteenth the gravity of
earth. This means that a person weighing 90kg on Earth would
weigh 6.2kg on Pluto.

25. Satelite Observations
In 2006 NASA launched a
satellite with a destination of
Pluto. This is the first of its
kind and is named New
Horizons.
New Horizons will reach Pluto
in 2015 and will study the
surface of the Planet and its
orbiting moons.
An artist's drawing shows the New Horizons spacecraft
as it nears Pluto. The moon Charon is in the distance.

Physics Laboratory/Southwes

26. Moons
Pluto has 5 known moons orbiting it. These moons were not discovered
at once and in fact the latest discovered moon of Pluto was found 34
years after the first.
• Charon (1978)
• Nix and Hydra (2005)
• Kerberos (2011)
• Styx (2012)

27. CONCLUSION
The planets in our solar system range in size
from small, rocky worlds to gigantic balls of gas
and ice. Orbiting these planets is a variety of
moons that vary from asteroid-sized chunks of
rock to planet-sized spheres with their own
atmospheres. Each of our planets has significant
characteristics, which makes each planet as
special as the other.
