The document provides an outline of topics related to the solar system, including the birth of the solar system, geocentric and heliocentric theories, an overview of the solar system components, and more detailed information about planets, dwarf planets, asteroids, comets, and other celestial bodies. It describes the terrestrial and Jovian planets, important moons like Jupiter's Galilean moons and Saturn's rings, the asteroid belt, Kuiper belt, dwarf planets like Pluto and Eris, and defines asteroids, meteoroids, meteors, meteorites, and comets. The document aims to inform about the key components, structures, and theories regarding our solar system.

6. THE SOLAR SYSTEM
The name given to the Sun and the family
that orbits it. “Solar” means “of the Sun”
and the sun is by far the most important
member of the family.
- The Sun has a “pulling force” known as
“gravity” that keeps the planets flying off
into space.

7. THE SOLAR SYSTEM
- Solar System‟s diameter is estimated to be
10
around 1.41x10 m. or 10 light hours
12
(1 light years= 9.46x10 m.)
- The sun and the solar system is located
within the outer limits of milky way galaxy.

cratered and very old; it
has no plate tectonics.

13. Venus

varied and interesting
terrain of any of the
terrestrial planets

Deimos

18. JOVIAN PLANETS
(OUTER PLANET/ GAS GIANTS)
Jupiter, Saturn, Uranus, Neptune

19. Jupiter
 Fifth planet from the
sun and by far the
largest planet.
Also known as Jove
Greek: Zeus (the king
of the gods)
 it is a gas planet,
which means that it
does not have solid
surface.

20. Jupiter‟s Red Spot
 The Great Red Spot,
a huge storm of
swirling gas that has
lasted for hundreds of
years.
 When it is in nighttime
sky, Jupiter is often
the brightest „star‟ in
the sky

21. Moons of Jupiter
Jupiter has 62 known satellites: the four
Galilean moons plus many more small
ones.
We‟ll take a look at the four large Galilean
moons which were first observed by
Galileo in 1610.

22. Io
 Io is the fifth moon
of Jupiter. It‟s the
third largest of
Jupiter‟s moons.
 Io has hundreds of
volcanic calderas.
Some of the
volcanoes are
active.

23. Europa
 Europa is the sixth of
Jupiter‟s moons and is
the fourth largest.
 It is slightly smaller than
the Earth‟s moon.
 The surface strongly
resembles images of sea
ice on Earth. There may
be a liquid water sea
under the crust.
 Europa is one of the five
known moons in the solar
system to have an
atmosphere.

24. Ganymede
 Ganymede is the
seventh and largest of
Jupiter‟s known
satellites.
 Ganymede has
extensive cratering
and an icy crust.

25. Callisto
 Callisto is the eighth of Jupiter‟s known satellites
and the second largest.
 Callisto has the oldest, most cratered surface of
any body yet observed in the solar system.

26. Saturn
 Saturn is the second largest planet and the sixth
from the sun.
Roman: Saturn (god of agriculture)
 Saturn is made of materials that are lighter than
water. If you could fit Saturn in a lake, it would
float!

27. Rings of Saturn
 Saturn‟s rings are not
solid; they are
composed of small
countless particles.
 The rings are very
thin. Though they‟re
250,000km or more in
diameter, they‟re less
than one kilometer
thick.

29. Uranus
 Uranus is the third
largest planet and the
seventh from the sun.
 Uranus is one of the
giant gas planets.
Ancient Greek: Uranus
(deity of heavens)
 Uranus is blue-green
because of the
methane in its
atmosphere.

30. MOONS OF URANUS

31. Neptune
 Neptune is the fourth
largest planet and the
eight from the sun.
Roman: Neptune
(god of the sea)
Greek: Poseidon
 Like Uranus, the
methane gives
Neptune its color.

32. MOONS OF NEPTUNE

33. ASTEROID BELT
the region of the Solar System located
roughly between the orbits of
the planets Mars and Jupiter. It is occupied
by numerous irregularly shaped bodies
called asteroids or minor planets. The
asteroid belt is also termed the main
asteroid belt or main belt to distinguish its
members from other asteroids in the Solar
System such as near-Earth asteroids and
trojan asteroids.

35. KUIPER BELT
The Kuiper Belt is a disc-shaped region of
icy objects beyond the orbit of Neptune --
billions of kilometers from our sun. Pluto
and Eris are the best known of these icy
worlds. There may be hundreds more of
these ice dwarfs out there. The Kuiper Belt
and even more distant Oort Cloud are
believed to be the home of comets that
orbit our sun.

43. ASTEROID, METEOR,
COMETS

44. ASTEROID
 Asteroids are small
Solar System
bodies that are not
comets, and historically
referred to objects
inside the orbit of
Jupiter. They have also
been called planetoids,
especially the larger
ones

45. BIYO
Despite often being called a planet, the lump of rock
known as 13241 Biyo (1998 KM41) is actually an
asteroid!
Some people argue that Biyo is a minor planet (the
name given to any planet smaller than a dwarf planet
like Pluto), but it isn't officially classed as one.
It is named after Filipino teacher Dr. Josette T. Biyo.

46. Meteoroid, Meteor, Meteorite
 A meteoroid is a sand- to boulder-
sized particle of debris in the Solar
System. (outside the planets
atmosphere)
 A meteor is the visible streak of
light from a meteoroid that is
heated as it enters a
planet's atmosphere
 A meteorite is a meteoroid fallen
to the planet‟s ground.

47. COMETS
 A comet is an icy small
Solar System body
(SSSB) that, when
close enough to the
Sun, displays a
visible coma (a thin,
fuzzy, temporary
atmosphere) and
sometimes also a tail.
