2. Have you ever
wondered where
Earth fits in the
entire universe??

3. When you look at the sky at night you may see the
moon among many stars. In the daytime you know the sun
is shining on us. We have learned that Earth where we live
revolves around the sun. Planet earth and its lone moon
belong to the solar system, where the sun is the center.
The solar system consists of an average star we call the
Sun, the planets Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus, and Neptune. It Includes the satellites of
the planets; numerous comets, asteroids, and meteoroids.

The Sun

6. The SUN
 The sun is the center of the solar system. The sun
provides the Earth and other planets light and heat .
 Although the sun is the largest object in the solar
system, it is only a medium-sized star.
 It is a yellow dwarf star made of a huge ball of hot
hydrogen and helium gases. It has a diameter of
1392000 km, which is 100 times the diameter of the
Earth.
 It also has a very strong pulling force called gravity. It
is the responsible in maintaining the members of the
solar system in their respective orbits.

 Mercury is the smallest planet and is the nearest
to the sun. Because of its closeness to the sun,
Mercury experiences extreme temperature.
 Mercury has a very thin atmosphere, made up
mostly of very thin amount of helium gas. It has
no moon and has a very weak magnetic field.

14. VENUS
 Venus is the second planet from the sun. It is
often referred to as the twin planet of Earth
because they are almost similar in size and mass.
 It is regarded as a beautiful bright star. Venus is
often called the evening star or the morning star.
 The atmosphere of Venus is made up mostly of
dense clouds of carbon dioxide and sulfuric acid.

15. Earth

16. EARTH
 Earth is the third planet from the sun. It is the only
planet in the solar system that maintains life.
 About 70% of the Earth’s surface is made up of water
while landforms make up the 30% of the earth. The
presence of oxygen and water in the atmosphere
protects the planet from the sun’s harmful radiation.
 The atmosphere of the earth is composed of gases like
nitrogen, oxygen, and carbon dioxide. When we
breathe, we take in oxygen from the air and give-off
carbon dioxide while plants take in carbon dioxide to
make food for human beings and animals.

17. Mars

18. MARS
 The fourth planet from the sun is the Mars. This
planet is smaller than Earth.
 The atmosphere of Mars is composed of carbon
dioxide with small amounts of other gases. It has
a very cold temperature because of its distance
from the sun.
 Iron oxides, commonly known as rust, creates the
red color of Mars; hence, it is called the Red
Planet. Its red color can be seen with the naked
eye.

19. Jupiter

20. JUPITER
 Jupiter is the fifth planet from the sun. It is the
largest planet in the solar system. It is a giant ball
of gases.
 It has a thick atmosphere made up of hydrogen
and helium, and its clouds are made up of
ammonia and ice crystals.
 Jupiter is the brightest object in the sky after the
sun, moon, and Venus. With the use of a
telescope, you may able to see its cloud bands
and the Great Red Spot.

21. Saturn

22. SATURN
 Saturn is the sixth planet from the sun. it is the
second largest planet in the solar system.
 This planet is made up mostly of hydrogen and
helium, which are very light gases.
 Saturn is known as the Ringed Planet because of
its beautiful rings. It has 7 major rings which is
consists of thousands of ringlets that is made up
of dust, rocks, and icy boulders.
 Life does not also exist in this planet.

23. Uranus

24. URANUS
 The seventh planet from the sun is the Uranus.
 Uranus has a thick atmosphere made up mostly
of hydrogen and helium.
 Astronomers believe that methane and
hydrocarbons gives the planet its greenish blue
color.

25. Neptune neptune

26. NEPTUNE
 Neptune is the eight planet from the sun. Due to
its great distance from the sun, it takes this planet
165 years to orbit the sun.
 Neptune has a thick atmosphere of hydrogen,
helium, and methane. Methane gives the bluish
color of this planet.
 The Great Dark Spot is the storm system in
Neptune’s atmosphere.

27. DPLANETS
Dwarf Planets

28. DWARF PLANETS
 A dwarf planet is a celestial body that orbits
around the sun, is massive enough to be rounded
by its own gravity, has not cleared the
neighborhood around its orbit, and is not a
satellite.
 Aside from Pluto, the following are considered
dwarf planets: Ceres, Eris, Makemake, and
Haumea.

29. Asteroids ASTEROIDS

30. ASTEROIDS
 Asteroids are sometimes called miniature planets
or planetoids. They are large pieces of rocks,
some of which are mixed with metals.
 They have different shapes. Some are spherical
while many have irregular shapes.

31. Comets comets

32. COMETS
 A comet is a chunk of frozen gas and dirt which
orbits the sun. It is seen with a starlike head and
a tail of light.
 Most comets have three parts, namely, the
nucleus, the coma, and the tail.
 Comets may be classified according to the length
of time they orbit the sun. Comets may be short-
period or a long-period.

34. METEORS, METEOROIDS,
and METEORITES
 Meteors are grains of rock or dust traveling
through space at high speed and seen as streaks
of light when burning high in Earth’s atmosphere.
 Meteoroids are small pieces of metallic or stony
matter. They have different speed and orbits
around the sun.
 Meteorites are meteors that hit the Earth’s
surface.

37. Benefits We Get From
SOLAR ENERGY
The energy coming from the sun is called
solar energy. Solar energy supports all life on
Earth.
 Plants use solar energy in making food during
photosynthesis.
 People and animals get solar energy indirectly by
eating plants.
 People burn coal and oil to make machines run.

38. Harmful Effects of
the SUN
 Sunburn. Overexposure to the sun can happen
in just a few hours. A bad reaction includes
tenderness, pain, swelling, and blistering, and
may include fever, chills, and nausea. While there
is no cure for sunburn, wet compresses, cool tub
baths, and soothing lotions may help. If you have
a bad burn, see your dermatologist.
 Premature wrinkling. People who work or lay in
the sun without sufficient protection get sagging
cheeks and deep wrinkles that may make them
look much older. The sun can also cause
unsightly red, yellow, gray, or brown spots and
scaly growths that may develop into skin cancer.

39.  Skin cancer. Skin cancer is caused by too much
sun, both long-term exposure and bad sunburns.
More than 90 percent of all skin cancers occur
on parts of the body exposed to the sun. The
face, neck, ears, forearms, and hands are the
most common places for skin cancer to develop.
 Eye damage. The sun can cause cataracts and
other eye damage. Cataracts are one of the
leading causes of blindness.

40. A long-period comet takes 200
years or more to orbit the sun.
One example is the comet Bennet.
A short-period comet orbits the
sun once in 25 years or up to 200
years. One example is the
Halley’s comet.
