What is space?
 Space here means the Universe. The
Universe is the whole piece of…outside
the Earth. In this slideshow, we have
only included information about our
solar system.
Our Solar System…
 How many planets are there in our solar
system? 5? 6? 7? No. There are nine. Our
Solar System is a very interesting topic.
Recent research study shows that there are
more planets then we thought there was. The
nine are [excluding the sun];
 Mercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, Neptune and Pluto.
More about the previous slide
 Scientist believe there is more planets
than we thought. And, for your
information, there are actually planets,
already discovered, that are not
included in our Solar System list.
 They are some dwarf planets,one in the
Asteroid Belt and the other about twice
as far away as Pluto.
About Mercury…
 The time taken for
Mercury to take one
revolution around the
sun is 88 days. One self
rotation of Mercury takes
59 days. Because of the
fast revolution and the
slow rotation, on
Mercury, it takes176
days for the sun to
reappear in the same
place.
About Mercury…
 Mercury is a bare and rocky
 Do you know?
Mercury is the planet
closest to the sun.
But surprisingly, it
isn’t the hottest
planet in our Solar
System! The
hottest planet is
Venus.
place covered with deep holes
called craters. The largest
crater found on Mercury is
called Caloris,which is
1300km across in diameter.
There is almost no
atmosphere on Mercury.
Since there is no air on
Mercury to keep the heat in
and Mercury is the closest to
the sun, the temperature
difference is very big. In the
day,the temperature can
reach up to 400Degree
Celsius, and in the night, it
can be –173Degree Celsius.
About Venus…
 Venus is covered by very
thick clouds of Carbon
Dioxide, and have
droplets of sulphuric acid
in the upper clouds. This
forms the atmosphere.
Because of this, Venus
became extremely hot,as
the carbon dioxide traps
heat like the greenhouse
effect. As a result, the
temperature on Venus
can be above 450
Degree Celsius.
About Venus…
 Do you know?
Venus is one of the few
places in our solar
systems that have
live volcanoes!
 It takes Venus 225
days to complete
one revolution
around the Sun. But
one self-rotation of
Venus takes 243
days. So a day on
Venus is longer than
a year on Venus!
About Earth…
 Earth, so far, is the
only planet with
signs of life on it.
Yes, Earth is our
beloved home,
where we live. There
is one moon
revolving Earth. You
should know the
rest.
About Mars…
 Mars’s nickname is – the
Red Planet. This is
because the surface is
covered in red dust. Mars
is about one-quarter the
size of Earth and have a
very thin atmosphere.
One revolution around
the Sun takes 687
days,and one self
rotation takes 24 hours
and 37 minutes.
