The universe is the vast, all-encompassing expanse that includes everything that exists: galaxies, stars, planets, and all forms of matter and energy. It is a dynamic entity, expanding continually since the Big Bang around 13.8 billion years ago. Within this immense universe, our solar system is a relatively small part. It consists of the Sun, eight planets—including Earth—moons, asteroids, and comets, all bound by gravity. The solar system orbits the center of the Milky Way galaxy, illustrating the intricate relationship between cosmic structures and the universe's grand s

9. UNIVERSE
is large unimaginable
expanse of gas, stars, dust
clouds, and consists of
planets and galaxy.

10. Big Bang Theory

11. Steady State / Infinite Universe Theory

13. Pulsating Universe Theory

14. SOLAR SYSTEM
is the gravitationally bound
system comprising the Sun
and the objects that orbit
around it, either directly or
indirectly.

15. SOLAR SYSTEM
it is in constant motion, with
the planets and their moons,
comets, asteroids and other
space objects revolving
around the Sun.

18. The masses of the planets are
also concentrated in the Gas
Giant planets Jupiter, Saturn,
Uranus, and Neptune.

19. •The large mass of these
planets comes from
their absolute sizes, not
their densities.
•The inner planets are
by far the most dense.

20. TERRESTRIAL (Inner Planets)
•made of materials with high melting points
such as silicates, iron , and nickel
•rotate slower, have thin or no atmosphere
Mercury Venus Earth Mars

21. JOVIAN
(Outer Planets)
•gas giants
•rotate faster
•have thick
atmosphere

23. PLANET BIYO
is a minor planet named after a
Filipino teacher, Dr. Josette Biyo
Planet
13241
Found in
the Main
Asteroid
Belt
between
Mars and
Jupiter

24. 1) MERCURY
•INNERMOST AND
SWIFTEST PLANET
•ALBEDO 0F 6%

DAYS
•TEMPERATURE RANGE OF -300F TO 800F
•VERY LITTLE ATMOSPHERE

26. 2) VENUS
•SIMILAR IN SIZE, DENSITY AND MASS
TO EARTH
•THICK CLOUD OF
CARBON DIOXIDE
•SURFACE TEMPS OF 900F DUE TO GREENHOUSE
EFFECT
•ATMOSPHERIC PRESSURE IS 90 TIMES THAT OF EARTH
•IF EARTH IS HEAVEN THEN VENUS IS HELL

29. 4) MARS
•WHITE POLAR ICE CAPS
•HAVE GREAT RIFT VALLEY
•VERY DRY PLANET
•REDDISH ROCK, SAND AND
SOIL

31. 5) JUPITER
•2 1/2 TIMES LARGER THAN ALL
OTHER PLANETS COMBINED
•1 DAY LASTS 10 HOURS DUE TO FAST ROTATION
•HURRICANE-LIKE STORM SYSTEMS
WITH WINDS OF 1000 MPH -GREAT
RED SPOT
•SURFACE OF LIQUID HYDROGEN OCEAN
•SOME MOONS [61] AS LARGE AS MARS

33. MOONS OF JUPITER
DISCOVERED BY GALILELO
61? TOTAL MOONS
•CALLISTO

REVOLUTION
•SYSTEM OF
RINGS
•HIGH WIND SPEEDS
1000+ MPH

36. 7) URANUS
•SURROUNDED BY POLAR CIRCLING RINGS
•KNOWN AS THE GREEN PLANET
•METHANE IN
ATMOSPHERE
•ROTATES ON ITS SIDE

38. 8) NEPTUNE
•TWIN PLANET TO URANUS
•BY POLAR CIRCLING RINGS
•KNOWN AS THE GREEN PLANET
•METHANE IN ATMOSPHERE
•ROTATES ON ITS SIDE

40. 9) PLUTO
•MAY NOT BE A PLANET
BUT A TRANSITION

PLANET
•AVERAGE TEMP OF -350F
•LARGE DIRTY
ICEBALL
•248 YEARS TO ORBIT SUN

41. MINOR MEMBERS OF THE SOLAR SYSTEM
1) COMETS
2) ASTEROIDS
3) METEOROIDS

42. MINOR MEMBERS OF THE SOLAR SYSTEM
COMETS
Often compared to large, “dirty snowballs”
Composition:
•Frozen gases
•Rocky and metallic materials
•Frozen gases vaporize when near the Sun
•Produces a glowing head called the coma
•Some may develop a tail that points away from
Sun due to radiation pressure and the solar wind

46. MINOR MEMBERS OF THE SOLAR SYSTEM
ASTEROIDS
•Irregular shapes AND Origin is
uncertain
•Most lie between Mars and Jupiter
•Small bodies –largest (Ceres) is about 620 miles in
diameter
•Some have very eccentric orbits
•Many of the recent impacts on the Moon and Earth
were collisions with asteroids

47. THE ORBITS OF MOST ASTEROIDS LIE BETWEEN
MARS AND JUPITER

48. MINOR MEMBERS OF THE SOLAR SYSTEM
METEOROIDS
•are called meteorswhen they enter Earth’s
atmosphere
•are called as meteoriteswhen they are
found on Earth
•A meteor shower occurs when Earth
encounters a swarm of meteoroids
associated with a comet’s path
