REASONISDISTANCE
E.G. Airplane also looks small when it is flying at a great height

8. CONSTELLATIONS
What are Constellation ?
The group of star which forms various patterns.There

bodies known as asteroids and meteoids form the solar
system

13. THE SUN

15. INTERESTING FACTS ABOUT PLANETS
Mercury is nearest to the sun.
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), 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.”

19. SATELLITE

20. ASTEROIDS

21. METEROIDS
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
