You must have noticed that all
objects look smaller when seen from a
distance. How small an aeroplane looks

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 (Sapta-

stars (Figure 1.1) that forms a part of
Ursa Major Constellation. Ask someone
elder in your family or neighbourhood
to show you more stars, planets and
constellations in the sky.
