You can see the full moon only once in about
a month’s time. It is Full moon night or Poornima. A
fortnight later, you cannot see it at all. It is a New
moon night or Amavasya. On this day, you can watch
the night sky best, provided it is a clear night.

[Niharika✩]

This is important

yessss

[Niharika✩]

The sun, the moon and all those objects shining in
the night sky are called celestial bodies.

[Niharika✩]

my fav para: Some celestial bodies are very big and hot. They
are made up of gases. They have their own heat and
light, which they emit in large amounts. These celestial
bodies are called stars. The sun is a star

While watching the night sky, you
may notice various patterns formed by
different groups of stars. These are
called constellations. Ursa Major or
Big Bear is one such constellation. One
of the most easily recognisable
constellation is the Saptarishi (Saptaseven, rishi-sages). It is a group of seven
stars (Figure 1.1) that forms a part of
Ursa Major Constellation.

*me like duh! my name means constellations!*

They simply glow without
any flicker just as the moon shines.
instead of they it will be stars

[Niharika✩]

Some celestial bodies do not have their own heat
and light. They are lit by the light of the stars. Such
bodies are called planets

Are you serious?

there is more info on these topics and instead of 6th you have 8th written on your i-card

The word ‘planet’ comes from
the Greek word “Planetai” which means ‘wanderers’

Is this important? It sure is interesting!

[Niharika✩]

It gets all its
heat and light from the sun, which is our nearest star.
If we look at the earth from a great distance, say the
moon, it will appear to be shining just as the moon.

interesting

[Niharika✩]

The moon that we see in the sky is a satellite. It is a
companion of our earth and moves round it. Like our
earth, there are seven other planets that get heat and
light from the sun. Some of them have their moons too.

THE SOLAR SYSTEM
The sun, eight planets, satellites and some other
celestial bodies known as asteroids and meteoroids

[Niharika✩]

The Sun
The sun is in the centre of the solar system. It is huge
and made up of extremely hot gases. It provides the
pulling force that binds the solar system. The sun is
the ultimate source of heat and light for the solar
system. But that tremendous heat is not felt so much
by us because despite being our nearest star, it is far
away from us. The sun is about 150 million km away
from the earth.

yes yes

All the eight planets of the solar system move
around the sun in fixed paths. These paths are
elongated. They are called orbits. Mercury is nearest
to the sun. It takes only about 88 days to complete
one round along its orbit. Venus is considered as
‘Earth’s-twin’ because its size and shape are very much
similar to that of the earth.
Till recently (August 2006), Pluto was also
considered a planet. However, in a meeting of the
International Astronomical Union, a decision was
taken that Pluto like other celestial objects (Ceres, 2003
UB313) discovered in recent past may be called
‘dwarf planets.

Time to slap the book

The Earth
The earth is the third nearest planet to the sun. In
size, it is the fifth largest planet. It is slightly flattened
at the poles. That is why, its shape is described as a
Geoid. Geoid means an earth-like shape.
Word Origin
Many words used
in a language may
have been taken
from some other language.
Geography, for example, is
an English word. It has its
origin in Greek, which
relates to the description
of the earth. It is made of
two Greek words, ‘ge’
meaning’ ‘earth’ and
‘graphia’ meaning ‘writing’.
Find out more about the
earth.
Do you know?
‘Sol’ in Roman
mythology is
the ‘Sungod’.
‘Solar’ means
‘related to the sun’. The
family of the sun is,
therefore, called the solar
system. Write down as
many words using the word
solar on your own as you
can.
Do you know?
Humans have
always been
fascinated gazing at the night
sky. Those who study the
celestial bodies and their
movements are called
astronomers. Aryabhatta
was a famous astronomer of
ancient India. He said that
the moon and the planets
shine due to reflected
sunlight. Today, astronomers
all over the world are busy
exploring the universe.

THE EARTH IN THE SOLAR SYSTEM 5
Conditions favourable to support life are probably
found only on the earth. The earth is neither too hot
nor too cold. It has water and air, which are very
essential for our survival. The air has life-supporting
gases like oxygen. Because of these reasons, the earth
is a unique planet in the solar system.
From the outer space, the earth appears blue
because its two-thirds surface is covered by water. It
is, therefore, called a blue planet.

i can say it without this

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

THIS IS AN INSULT

[Niharika✩]

The Moon
Our earth has only one
satellite, that is, the
moon. Its diametre is
only one-quarter that of
the earth. It appears so
big because it is nearer to
our planet than other
celestial bodies. It is
about 3,84,400 km away
from us. Now you can
compare the distance of
the earth from the sun
and that from the moon.
The moon moves around the earth in about 27 days.
It takes exactly the same time to complete one spin. As
a result, only one side of the moon is visible to us on
the earth.
The moon does not have conditions favourable for
life. It has mountains, plains and depressions on its

[Niharika✩]

surface. These cast shadows on the moon’s surface.
Look at the full moon and observe these shadows.

[Niharika✩]

Asteroids
Apart from the stars, planets and satellites, there are
numerous tiny bodies which also move around the
sun. These bodies are called asteroids. They are found
between the orbits of Mars and Jupiter (Figure 1.2).
Scientists are of the view that asteroids are parts of a
planet which exploded many years back.
Meteoroids
The small pieces of rocks which move around the sun
are called meteoroids. Sometimes these meteoroids
come near the earth and tend to drop upon it. During
this process due to friction with the air they get heated
up and burn. It causes a flash of light. Sometimes, a
meteor without being completely burnt, falls on the
earth and creates a hollow.
Do you see a whitish broad band, like a white
glowing path across the sky on a clear starry night? It
is a cluster of millions of stars. This band is the Milky
Way galaxy (Figure 1.6). Our solar system is a part of
this galaxy. In ancient India, it was imagined to be a
river of light flowing in the sky. Thus, it was named
Akash Ganga. A galaxy is a huge system of billions of
stars, and clouds of dust
and gases. There are
millions of such galaxies
that make the Universe.
It is difficult to imagine
how big the universe is.
Scientists are still trying
to find out more and more
about it. We are not
certain about its size but
we know that all of us –
you and I belong to this
univers
