The document summarizes key information about our solar system. It describes the eight planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune - in order from the Sun, including their composition and namesake gods. It also mentions the Sun is at the center of the solar system and is a massive ball of hot gases that provides light and heat to allow life on Earth. Pluto is noted to no longer be classified as a planet.

1. THE SOLAR SYSTEM
Science 2

2. Our Solar system
 We
live on the surface of the Earth. The
Earth is one of eight planets that orbit
around a big star we call the Sun.

3. The Planets

4. The Planets
A
planet is a celestial
body orbiting a star.
The names of the
eight planets in our
Solar System are:
 Mercury
 Venus
 Earth
 Mars
 Jupiter
 Saturn
 Uranus
 Neptune

5. Orbits
 Orbits
are the circular movements the
planets describe around the sun. The
closer the planet is to the sun, the faster it
moves.
 The Earth takes exactly one year to
describe an orbit around the sun.
 The rest of the planets spend more or less
time to travel round the sun.
 They are named after Roman gods.

6. Mercury
 It
is the closest planet
to the sun.
 It is made of rock
 It is very small
 It travels faster than
all the others, so it
was named after the
messenger god.
 Planets

7. Venus
 It
is the second planet
from the sun.
 It’s very hot and it’s got
a toxic atmosphere
 It’s the same size as the
Earth
 You can see it at dawn
and it looks so beautiful
that was named after
the godess of beauty
 Planets

8. Earth
 It
is our planet, the only
we know having living
things.
 It is covered by water,
land and air.
 The temperature is
mild
 It has a satellite called
the Moon
 Planets

9. Mars
 It
is made of rock,
frozen ground and
iron
 It is half the size of
Earth
 Scientist believe there
is ice (water) on the
poles.
 It is red, so it was
named after the god
of war.
 Planets

10. Jupiter
 It
is the biggest planet
in our Solar System
 It is made of gases,
and there are huge
storms on its surface
 It has more than 16
moons around it.
 As it is the biggest
one, it was named
after the king of gods
 Planets

11. Saturn
 It
is made of gas, and
its beautiful rings are
made of ice and rocks
 It has more than 30
satellites
 As it is so far from the
Sun, it takes a lot of
time to orbit, so it was
named after the god
of time
 Planets

12. Uranus
 It
is another of the
four cold giant gas
planets
 It is made of frozen
gas and ice
 It is blue, so it was
named after the god
of the sky
 Planets

13. Neptune
 It
is the eighth planet
from the sun.
 It is very big, made of
light gases
 It has eight satellites
 It has a color similar
to the ocean, so it
was named after the
god of the seas.
 Planets

14. Pluto
 It
is not considered to
be a planet anymore,
as it hasn’t got a
normal orbit
 It is very small and
cold and it is made of
rock
 As it is so very far
from the sun, it was
named after the god
of death
 Planets

15. The Sun
 The
Sun is our star. All planets in our solar
system orbit around it, including the Earth.
 The Sun is an enormous mass of very hot
gases (Helium and Hydrogen) in
continuous explosion
 These nuclear explosions give light and
heath to the Earth, so that life can be
possible.
 Never look direclty at the Sun or it might
blind you!
