The Sun is nearly 600
times larger than all
the planets in our
Solar System put
together.
The sun is the center of
the Solar System.
All the planets revolve
around the sun.
Mercury is the closest
planet to the sun .
It has the fastest rotation
out of all the planets.
Mercury has no moons or
rings.
Mercury has a lot of craters
because it doesn’t have
enough atmosphere to
protect the surface from
meteoroids, asteroids,

Venus has no moons or no rings.
It is called Earth’s twin because it is the
closest to its size and shape.
It also has an atmosphere like Earth’s.
Earth has a lot of water so they sometimes
call it the Blue Planet.
The Earth has one moon and no rings.
It takes 365 days to rotate around the sun.
The Earth is always changing .
The Earth is tilted at an angle of 23.5 that is
why we have seasons.
Mars has two moons and no
rings .
At night it is the only Planet
with a red glow.
The color comes from the
iron soil it has.
Mars has the biggest
volcano in the Solar
System it is called
Olympus Mons.
It is eighteen miles high.
Saturn is the second biggest
planet in our Solar
System.
Saturn has 18 moons and 7
major rings.
It was named after the
Roman God of the
harvest.
Saturn’s rings are made of
billions of bits of icy
debris.
Uranus takes 17 Earth
hours for one day.
It takes 84 Earth years
to orbit all the way
around the sun.
Uranus has 17 moons
and 11 rings that are
tilted to it’s side.
Neptune is the eight
planet from the sun.
It’s rotation for one day
is about sixteen Earth
hours.
It has eight moons and
four rings.
For it to rotate around
the sun it takes about
164 Earth years.
Pluto is known as the ice
planet.
It is the ninth planet from the
sun.
It has one moon and no
rings.
The rotation for one day
takes about six Earth
days.
The rotation for one year
takes about 248 Earth
years.
Stars are huge balls of
glowing gases .
As a star gets older it
changes, temperature
gets warmer.
When the stars get older
they are a blue and white
mixture.
Middle aged stars are
yellow and not as hot,
because they have a lot
of hydrogen fuel.
The Solar System is a
collection of planets
and other spinning,
speedy objects
revolving around a
medium-sized star
located in the Milky
Way Galaxy.
The Solar System
contains nine planets
and the sun.
The World’s largest known
meteorite- named Hobawas discovered in 1920
on a farm in
Namibia, a country in
Southwest Africa.
A meteorite is when a big
enough rock travels
through the atmosphere
without burning up.
Buzz Aldrin and Neil
Armstrong were the first
American people to reach
the Moon.
The Moon’s orbit around the
Earth takes 27 Earth
days.
The Moon rotates very
slowly on it’s axis at
exactly at the same
amount of time to go
around the sun.
Comets are dirty snowballs.
A Comet is a dirty snowball
that travels through the
atmosphere without
burning up.
Comets that come into the
inner Solar System travel
around the Sun in
elliptical orbit.
Some Asteroids are
made up of rock
similar to the rocks
you find on Earth.
Other Asteroids contain
a lot of carbon the
same thing your
pencil led you write
with witch makes
them very dark.
Earth is the only planet
that water covers twothirds of Earth’s
surface.
250 million years ago all
of Earth’s continents
were joined together
in one large land
mass called Pangaea
which means all
Earth.
There are many types of
galaxies.
The first galaxy is the spiral
galaxy.
They turn in space but take
a million years to go
around once.
The second galaxy is the
irregular galaxy.
They have no special shape
and they will eventually
turn into stars.
The third galaxy is the
elliptical galaxy.
They are an oval
shaped galaxy.
The galaxy contains the
Milky Way .
There are about 100
billion stars in the
galaxy.
