Cut out different sized planets,
moons, stars, comets, meteorites,
rings and a sun.
2. Place all of your Solar System
on the black poster paper and then
glue each one to the paper.
Our Solar System Facts

Planets - Pluto
Our Solar System
: is made up of the Sun and everything
that orbits it [the nine (eight) planets
moving in elliptical orbits
around it]. There are also a lot of
asteroids (small lumps of rock). The
moons orbit the planets.
Mercury and Venus are the only planets
that do not have any moons. The
Sun's gravity keeps
the planets and a variety of other
objects, including comets, moving
the way they do because of the Sun's
Sun : (Sol) :The
Sun is a star,
a huge ball of gases - mainly hydrogen
and helium. Stars make their own
light, heat and energy. It takes
eight and a half minutes for our
Sun's light to reach our plante
Earth moving at 300,ooo km (186,451
miles) a second. The sun is
the largest object in our Solar
System. Millions of stars form a galaxy.
The stars in a galaxy are held
together by the force of gravity
between them. There are millions
of galaxies in the Universe.
All the planets orbit the Sun in
the same direction.
All the planets are made up of different
materials. Their differences
are mainly the result of their different
distances from the Sun.
Mercury : (Morning
Star/Evening Star) – Mercury
is a very small planet and is the
closest planet to the Sun. This planet
is extremely hot during the day and
very cold at night. Mercury is mainly
made up of iron. Mercury does not
have any moons and is so much smaller
than Earth. It is covered with craters.
Venus : is Earth’s
system planet – it is identical
in size to Earth. It is the closest
planet to Earth. This planet is different
from all the other planets as it spins
backwards. Its poisonous clouds trap
the Sun’s heat, making Venus
the hottest of all the planets. Venus
does not have any moons.
Earth : Earth is
the only planet in the solar system
to have life discovered. It is the
same size as Venus. Earth is the third
rock from the Sun.
Moon - Earth has
one moon called Luna.
The Earth's Moon
:Your weight depends on your mass
and on the strength of the Earth's
gravity. The moon is smaller than
the Earth, so its gravity is less.
The moon's gravity is about one-sixth
of the Earth’s gravity. If you
could go to the moon your mass would
be the same, but your weight would
Mars : Sometimes
called the ‘Red Planet’
because the rocks and soil are a reddish
brown colour. Mars is much colder
than Earth and is about half its size.
Moons - Mars has
two moons call Deimos and Phobos.
Jupiter : is the
king of the planets. It is the first
and largest of the giant gas planets.
It is beautiful coloured with streaks
and swirls caused by winds and storms
– Jupiter has a big Red Spot
which is a giant storm.
Moons : Jupiter
has 63 moons.
Saturn : is the
second largest planet and has more
moons than any other planet. The rings
of Saturn are bands of ice and rock
and they are bright and very beautiful.
Moons : Saturn
has 34 moons
Uranus : is bigger
than Earth and spins on its side.
It is identical to Neptune . Uranus
is a bluey-green ball made of gas
and water, with molten rock at its
Moons : Uranus
has 27 moons. Five are large and the
rest are small.
Neptune : is the
smallest of the gas giants and has
very dark rings. It is a blue ball
with many white clouds. Neptune has
a giant storm much like the storm
on Jupiter ‘The Great Dark Spot’.
It has six rings which circle the
Moons : Neptune
has 13 known moons.
Pluto : Pluto was
changed from a planet to "The
Dwarf Planet" in 2006. Because
it is so small many scientists don’t
consider it a planet at all.
Moons : Pluto has
We now only
have 8 planets (instead of 9)
- Mercury, Venus, Earth, Mars and
Pluto are rocky planets.
- Jupiter, Saturn, Uranus and Neptune
are made mainly of gas.
Inner Planets :
The four planets closest to the Sun
are known as the inner plants.
They are rocky planets.
: The other planets are the outer
planets. Except for Pluto,
the outer planets are made of gas.
Asteroids : most
of the asteroids have orbits between
Mars and Jupiter,
Comets : are made
out of dust and ice, kind of like
a dirty snowball. Comets are soaring
beacons with their beautiful tails.
Atmosphere : our
Earth's atmosphere is made up of
a transparent mixture of several
gases surrounding our planet and
held by Earth's gravity. The mixture
of these gases is known to us as
air or oxygen. Our atmosphere
protects our life on planet Earth
by absorbing the ultraviolet solar
radiation and reducing the temperature
extremes for night and day.
