9. Relative distribution of the two types of Planets
Gas giant worlds are far from the Sun
Rocky worlds are close to the Sun

10. Bruno was burned alive for speculating that the stars are similar sun,
perhaps having planets and some of them may even harbour life. Today
it is no longer a mere speculation. In fact till now more than
460 exso-planets that is planets of other stars have been discovered.
Many of them are massive like Jupiter. What an irony!

11. ivaSvaacaI ]%p<aI ( Origin of Universe ) :
Time starts now ………

12. About 460 crore years ago there was a very big and colossal gas cloud-
primordial solar cloud. The cloud rotated about itself due to self gravity
and began to shrink. In the center the mass accreted and became
dense. Most of the mass in the cloud concentrated at the center
resulting in the birth of sun. As the core of this sun became more
massive and denser the temperature rose to an extent that
thermonuclear reaction – fusion could take place. Sun started to shine.

13. While the rest of the
material went around
and around the central
mass. Small dust
particles were attracted
initially by electrostatic
attraction. Once the
small rocks became
sufficiently bigger gravity
also played a part.
Slowly the proto planets
were formed.

14. Proto planets fused to gather to
form planets like Mercury, Earth
and so on. Gas giants like Jupiter
and Saturn were formed by the
accretion of the light elements.
The icy materials and gases like
methane became Uranus and
Neptune.

15. The leftover proto planets became the kuiper cloud while the left over
original material became the Oorth cloud. The materials that failed to
accrete into a planet due to the gravitational perturbation of Jupiter
became asteroid belt.
Initial phase of solar evolution was full of bombardments. One result is
pockmark like craters on Moon, Mercury and so on. As most of the
space rocks in the inner region got exhausted the bombardment
tapered off around 3 billion years ago.
On such bombardment resulted in the formation of moon. Once it was
postulated that moon could have formed due to accretion of materials
around Earth, could have been captured or could have split from Earth
Recent studies indicate that Mars like proto planet impacted on
Earth and moon resulted from the debris that was thrown out.

16. saaOrmaalaocaI inaima-tI ( Origin of Solar System ) :

18. The formation of solar system is not pure guess work. Looking at the
night sky one can clearly see evidence of gas cloud accreting, star
formation, accreting disk, planet formation.

19. Activity opportunity: Powers of 10
Surface
Body Radius Volume
Area
Earth 1 1 1
Jupiter 10x [101] 100x [102] 1000x [103]
Sun 100x 10,000x 1,000,000x

20. Dwarf Planets
The IAU currently recognises five dwarf planets—Ceres, Pluto, Haumea,
Make make, and Eris.
Ceres is in the asteroid belt others in the Kuiper belt.
Many Kuiper Belt objects, exist in what is believed to be a vast shell of
icy and rocky objects that live at the very edge of our solar system.

21. After moon brightest celestial object in the night sky is Venus.

22. Moon with Shinning Venus

23. Venus Phases in April-May 2004

24. Ptolemy's system Copernicus’s system
Galileo Galilee used telescope to observe Venus. On
seeing the waxing and waning phases of Venus, just
like that of Moon, Galileo concluded heliocentric solar
system.

25. Galileo discovered the four largest moon
of Jupiter on Jan 7, 1610?.
In his telescope the moons appeared as
tiny dots. The position of the dots
changed over days and he found that
they were orbiting Jupiter.

26. Jupiter & it’s 4 Moons

27. Jupiter & it’s 4 Moons

28. During July 1994 a comet named Shoemaker Levy was captured by
Jupiter and crashed on its surface.

30. Shani has been
much maligned
planet in Hindu
tradition.
Actually it is one
of the beautiful
planets with its
majestic rings.

31. Actually when Galilio looked at Saturn in
1610 through telescope he was stunned.
He perceived Saturn to have two
structures on both side.
With improved telescope in 1616 he
perceived it to structure like ears to a
face.
1655 Huygens could discern it to be a
ring like structure.
It was Cassani who in 1676 distinguish it
to be number of rings

32. Uranus also has rings, but
no so grand as Saturn.
13 March 1781 Uranus was
discovered by William Hershel
and his sister Carolina. It was
the first planet that found no
place in any bible, puran or
religious texts.

34. In olden days the sudden
appearance of Comets was
considered bad omen.
Comet was called Dumketu and
in various civilisations it was
imagined to be various scary
objects.
Norman king William considered
the appearance of comet in
1066 as good omen. A new star
a new king was his slogan. He
fought his enemies and became
the king of England.

35. As the sun rays evaporate and
makes the tail of the comet the tail
is prominent when it is nearer to
sun and it always points against the
sun

37. Moon goes around in elliptical orbit, tilted
at about 5 degree. Apogee is at 357200
km and perigee is 407100 km.
Light will take about 1.25 seconds to reach
Earth from moon. It takes about 27 ½ days to
go around Earth, but the period between each
full moon is about 30 days.

39. The relative position
of Earth, Moon and
Sun results in the
phases.
Though every new moon
day moon is in line with
Sun, due to the tilt of its
orbit, it will not cause
eclipse every new moon
day.

41. Eclipse seen from another planet ! Two moons of
Mars occasionally cause partial eclipse and
Pathfinder mission captured the eclipse that took
place in 2004.

42. Zodiac signs are mere constellation falling around Sun Path
