A simple description of our solar system

1. Solar
system

2. The Solar System consists of the Sun, eight planets, and other smaller constituents

3. The Inner Planets and Outer Planets
tell many tales about the wonders of the Solar System
While the gems in space unveils the myth of our galaxy
far beyond imagination..

6. •All the nine planets move around the Sun in a large oval path.
•The planets also spin by itself.
•The Sun is the only star in the solar system.
•A star is an object in space that gives out light and heat.
•The Sun is also the biggest object in the Solar System.
SUN
s
The Sun is in the centre of the
Solar System.
All the eight planets move around
the Sun in a large oval path.
The Sun is the only star in the
solar system.
A star is an object in space that
gives out light and heat.
The Sun is also the biggest
object in the Solar System.

7. mercury
Mercury is the nearest planet to
the Sun.
It is 58 million km from the Sun.
Its surface that faces the Sun has
a very high temperature of 430°c.
The temperature is too hot to
support life.
This high temperature causes no
liquid water to exist on this planet.
Mercury rotates very slowly.

8. venus
Venus is the second nearest planet to the
Sun.
It is the hotter than Mercury because a
great amount of the heat from the Sun is
trapped in its atmosphere.
It is the brightest object in the sky besides
our Sun and the Moon.
Nearly the whole atmosphere consists of
carbon dioxide.
Venus is often called Earth’s twin because
the two planets are close in size, but the
conditions on the surface of Venus are
completely different.

9. EARTH
Planet Earth is the third planet from the
Sun and the fifth largest planet in the
Solar System.
The Earth’s atmosphere, weather and
many other factors are just right to keep
us alive.
Earth is a complex system of air, water
and land.
Earth has one moon, its name is Luna.
The Earth’s interior is composed of four
layers, three solid and one liquid.

10. MARS
It is also called the Red Planet or
Red World because it is reddish in
colour.
Mars is the only planet whose
surface can be seen in detail from
the Earth.
Mars is the fourth planet from the
Sun.
It has a very cold surface so
almost all of its water is frozen.
Mars is not conducive for living
things.

11. JUPITER
Jupiter is the fifth planet from the
Sun .
It is the biggest planet in the solar
system.
It has a diameter of 3000 km.
Jupiter is usually the fourth
brightest object in the sky (after
the Sun, the Moon and Venus);
however at times Mars appears
brighter than Jupiter.
Jupiter has at least 63 moons.

12. SATURN
Saturn is the sixth planet from the
Sun.
Saturn is the second largest
planet in our Solar System.
Saturn has three wide rings. They
can be seen with a telescope.
Saturn has 34 moons.

13. uranus
Uranus is the seventh planet from
the Sun.
Uranus is lying on its side as it goes
round the Sun.
There are many layers of clouds
found in this planet's
atmosphere, however these clouds
are difficult to see.
Uranus has 27 moons.

14. Neptune
Neptune is the eighth planet from
the Sun.
Neptune is covered with a blue
ocean of liquid methane.
Neptune has 13 moons.
Neptune appears to have two thin
rings, with a third larger ring

between them. These rings are
previous
made up of dark rocky materials.

15. asteroids
Asteroids are huge chunks of
rocks and metals.
Asteroids have different
shapes and sizes. Most
asteroids have a diameter of
more than 200 km.
The main asteroids belt
occupies the orbit between
Mars and Jupiter.
Asteroids are left over
materials from the formation of
the Solar System.

16. meteoroids
A meteoroid is a piece of rock
that is floating in space.
There are millions of
meteoroids in the solar system.
Most of them are small.
Every day, a millions of
meteoroids enter the Earth’s
atmosphere from space.

17. meteor
Meteors are tiny rocks which
probably come from the
asteroids belt.
When a meteoroid enters the
Earth’s atmosphere, it burns
very brightly. Friction between
the meteoroid and the air
causes the meteoroid to
burn, is called a meteor.

18. comet
A comet is made of pieces of
ice in space.
It is made of water, dust and
frozen gases.
Comets have long glowing
tails.

19. SOLAR SYSTEM
The Sun and eight other
planets are part of the solar
system.
The eight planets are
Mercury, Venus, Earth, Mars,
Jupiter, Saturn, Uranus and
Neptune.
Natural satellites
(moons), meteors, comets
and asteroids are also the
constituents of the solar
systems.

20. INNER PLANETS
Mercury, Venus, Earth and Mars
are the four planets that are the
nearest to the Sun.
They are called the inner
planets.
All these planets are made of
rocks.
Each of the inner planet has an
atmosphere.
The atmosphere of the inner
planets is very thin and
poisonous to living things,
except the Earth.

21. OUTER PLANETS
The outer planets are Jupiter,
Saturn, Uranus, and Neptune.
They are mainly composed of
gases.
Their temperature is too cold to
support life.
