2. THE SOLAR SYSTEM
• The Solar System is a
collective name for the Sun
together with the groups of
celestial (heavenly) bodies
that are held in it’s gravity
and revolve around the Sun.
3. Members of the Solar System
• 1. The Sun- is a star, a huge
ball of hot gases with a
temperature of around
15,000,000 degrees Celsius at
the center and 5,000 degrees
Celsius at the surface.
4. Members of the Solar System
• 2. The Planets- classified
into four Terrestrial
(Mercury, Venus, Earth and
Mars) and four Gaseous or
Jovian (Jupiter, Saturn,
Uranus and Neptune)
6. Compositions of Planet
Gases, hydrogen an helium, are those
with melting points near absolute zero (0
Kelvin). These are the most abundant
constituents of the solar nebula.
Rocks, principally silicate minerals and
metallic iron which have melting points
that exceed 700ºC.
Ices, include ammonia, methane, carbon
dioxide and water. They have immediate
melting points.
8. 1. MERCURY
• Nearest planet to the Sun.
• It is very hot during the day, 426
degrees Celsius and very cold at
night -170 degrees Celsius.
• Surface has many craters
because it has no atmosphere.
9. 1. MERCURY
• Mercury has no moons.
• Rotation: 58 days, 15 hours, 30
minutes.
• Revolution: 88 days.
• The Fastest planet.
11. 2. VENUS
• Second planet from the Sun.
• Aside from the Sun, Venus is the
brightest object in the sky
commonly referred to as the
“Morning and Evening Star”
• Considered as the Twin Planet
of the Earth.
13. 2. VENUS
• Venus is known as the hottest
planet because of its very thick
atmosphere made up of Carbon
dioxide.
• The layer of Carbon dioxide traps
heat and results to Greenhouse
Effect, sending temperatures if
482 °C.
15. 2. VENUS
• The clouds of Venus are mostly
Sulfuric acid, which gives Venus
a yellow-white color. All the
rains in Venus are acid rain.
• The surface of Venus has faults
and volcanoes.
17. 2. VENUS
• Venus is the Earth’s closest
neighbor.
• It was the first planet to be
studied with space in 1962.
• Venus has no moons and the
gravity is as strong as the Earth.
25. 4. MARS
• Mars is known as the “Red Planet”,
its surface appears red-yellow
because of Iron oxide in the soil and
dust that covers most of the planet.
• Mars has a thin atmosphere
composed mostly of Carbon dioxide,
small amounts of Oxygen and
Nitrogen.
27. 4. MARS
• Mars has water in its atmosphere
but not enough to condense and
form clouds.
• Days on Mars are almost the
same as on Earth.
• Rotation: 24 hours, 37 minutes
• Revolution: 687 days
36. 5. JUPITER
• Jupiter is the largest gaseous
planet in our Solar System.
• It is more than 11 times the size
of Earth.
• The great mass of Jupiter enables
it to generate very strong
gravitational force.
38. 5. JUPITER
• Jupiter is a gaseous planet.
• Jupiter’s atmosphere is made up
of Hydrogen, Helium,
Methane, Ammonia and
Water Vapor.
• Jupiter has very small, faint dust
rings around it.
41. Jupiter’s Moons
• Jupiter has at least 63 moons.
• Four moons were first observed
by Galileo Galilei and was
named Galilean Moons-
Ganymede, Io, Europa and
Callisto.
43. Jupiter’s Moons
• Ganymede- largest moon in the
Solar System, bigger than Mercury.
• Io- has an active volcano
• Callisto- has water, made mostly of
rocks and ice.
• Europa- rock, thick smooth crust of
ice.
45. Jupiter’s Great Red Spot
• Most striking feature is the Great
Red Spot in the southern
hemisphere which is a
counterclockwise rotating storm.
• Rotation: 9 hours, 56 minutes
• Revolution: 12 years
47. 6. SATURN
• Saturn is the second largest
planet but has the lowest
density.
• 9.5 times larger than Earth.
• Radiates more energy into space.
• Rotation: 10 hours, 39 minutes
• Revolution: 29 years
48. Saturn’s Atmosphere
•Saturn is a
gaseous planet.
•It has a thick
atmosphere of
Hydrogen, Helium,
some Methane and
Water Vapor.
53. 7. URANUS
• Uranus is the third largest planet
with a system of 11 thin, dark rings.
• Discovered by William Herschel
on March 13, 1781.
• Atmosphere is made up of
Hydrogen, Helium and some
Methane which gives the planet’s
bluish- green color.
55. URANUS
• Uranus radiates the same amount
of solar energy it receives.
• Uranus’ axis of rotation is tilted at
84 degrees on its side.
• The result is its North Pole faces
the Sun for ½ of 84 years
revolution.
57. 7. Uranus
• Rotation: 17 hours, 14 minutes
• Revolution: 84 years
• Uranus’ gravity is a little stronger
than of the Earth.
• Has at least 21 moons, largest is
Titania.
60. 8. NEPTUNE
• Neptune is the fourth largest
planet.
• Neptune has an elliptical orbit.
• Atmosphere is made up of
Methane, which gives the bluish-
green color.
63. 8. NEPTUNE
• Neptune has a dark colored storm
called Great Dark Spot.
• Neptune has the fastest winds
in the Solar System.
• Neptune has at least 11 moons,
largest is Triton.
66. 8. NEPTUNE
• Neptune was discovered in Berlin
Observatory, Germany by Johann
Gottfried Galle on September 23-24,
1846.
• Rotation: 16 hours, 6 minutes
• Revolution: 165 years
