Introduction

In our solar system, nine planets circle around our Sun. The Sun
sits in the middle while the planets travel in circular paths (called
orbits) around it. These nine planets travel in the same direction
(counter- clockwise looking down from the Sun's North Pole). The
picture on the right shows the different paths and positions of each
planet.
The Solar System is made out of two
parts:
 The inner solar system contains
Mercury, Venus, Earth and Mars. These
four planets are closest to the sun.
The outer solar system contains
Jupiter, Saturn, Uranus, Neptune and Puto
 Each planet is named after God.

The inner planets separated from the
outer planets by the Asteroid Belt.


Mercury is the closest to the sun but it’s not
hot.
 Mercury
orbits the sun
once every
87.969 days.
 Mercury is
bright when
Viewed from
Earth, ranging
from – 2.3 to 5.7 inches. The sun is only
28.3’c. Since Mercury is normally lost in the
glare of the sun. Mercury can only be
viewed in morning or evening twilight.

Venus is the 2nd closest to the Sun
Orbiting it every 224.7 Earths

The planet is named after Venus,

the roman goddess of love and
beauty. After the Moon, it is the brightest
natural object in the night sky. Venus reaches
its maximum brightness shortly before sunrise
or shortly after sunset.

Earth
Earth is the 3rd planet near to the sun.

Earth is a living planet.


Mars is red.

engulf the
entire planet The effects of these storms
are dramatic, including giant dunes,
wind streaks, and wind-carved features.
Scientists believe that 3.5 billion years
ago, Mars experienced the largest
known floods in the solar system.
Jupiter
Jupiter is the
5th closest to
The sun. It’s the biggest planet.

Saturn
Saturn is the 6th planet near the sun. If
you put all nine planets in a bucket of
water only Saturn will float I think it is
because it has loads
Of rings. Saturn's ring
system extends
hundreds of thousands
of kilometres from the planet.

Uranus
Uranus is the 7th planet near
the the sun. The seventh planet from the Sun
is so distant that it takes 84 years to
complete one orbit. Uranus, with no Solid
surface, is one of the gas giant planets
(the others are Jupiter, Saturn, and
Neptune). Uranus gets its blue-green color
from methane gas. Sunlight is reflected
from Uranus' cloud tops, which lie beneath
a layer of methane gas.
Neptune

Neptune is the 8th planet near to the sun.
After being ignored by French
astronomers, Le Verrier sent his
predictions to Johann Gottfried Galle at the
Berlin Observatory, who found Neptune on
his first night of searching in 1846. .
Seventeen days later, its largest moon,
Triton, was also discovered. . Nearly 4.5
billion kilometres (2.8 billion miles) from the
Sun, Neptune orbits the Sun once every
165 years.
is the 9th planet near to the sun.
It does not exist any more.

Pluto tiny, cold and incredibly
distant, Pluto was discovered in 1930
and long considered to be the ninth
planet. People found out that it was a
Dwarf planet.
 Pluto
Sun
 The
sun is in the middle with all 9
planets orbiting the sun. The sun is a
big star but is made out of a big ball
of gas. The remainder consists of
the planets (including Earth),
asteroids, meteoroids,
comets, and dust in orbit.
Moon
The moon is bright. It comes in different
phases as it travels around earth.
 The the Moon's surface area is less than
a tenth of the Earth (about a quarter of
Earth's land area). It takes 29 days to
rotate around Earth. First man to land on
the moon was an
American astronaut
Neil Arm Strong.
