SYSTEM

2.  The Sun is the star at the center of the Solar System.
 It is a nearly perfect ball of hot plasma, heated to
incandescence by nuclear fusion reactions in its core,
radiating the energy mainly as light, ultraviolet, and infrared
radiation.
 It is the most important source of energy for life on Earth..
 Its surface temperature is 5,778 K.
 Its rotation speed is 1.997 km/s
SUN

3.  The Moon is Earth's only natural satellite. Together with
Earth it forms the Earth–Moon satellite system.
 It is about one-quarter of Earth in diameter.
 In the Solar System it is the fifth largest satellite, larger than
any of the known dwarf planets and the largest satellite of a
planet relative to the planet.
MOON

4. THE PLANETS IN THE SOLAR SYSTEM

5. Mercury is the smallest planet the solar
system
Mercury is the planet nearest to the sun it
has no moons.
If you weigh 100 pounds on earth ,you
would only weigh 37 pounds on mercury.
It takes less than 87.97 earth days for
mercury to orbit around the sun.
1 days last about 180earth days.
MERCURY

6. Venus is second planet from the sun
,Brightest planet in solar system
Venus is known as earths twin sister
because of its similar size and proximity to
each other.
Venus has a longer day than year.
It takes 243 days for Venus to make a
rotation.
Venus spins In a reverse gear
VENUS

7. Earth is the third planet from the sun and
the only astronomical object known to
harbor life.
Earth is also called blue planet
The earth is estimated to be 4.5 billions
years old.
It travels through space at 660,000 miles
per hour.
EARTH OUR (HOME)

8. Mars is the 4 closest planet to the sun . It
can easily seen from earth.
Mars is red because it is rusty. There is a
lot of iron in the soil, and the air on mars
has made it turn red
Mars orbit the sun every 687 the earth
days.
The martian “day” is about half a hour
longer than earth.
MARS

9. Jupiter is the largest planet in our solar
system.
Jupiter volume is large enough to contain
1,300 planets the size of earth.
Jupiter rotates faster than any planet in the
solar system . It rotates so quickly that the
days are only 10 hours ago.
But it takes 12 earth years for Jupiter to
complete an orbit around the sun .
If you weigh 100 pounds on earth , you
would weigh 264 pounds on Jupiter .
JUPITER

10. Saturn is the sixth planet from the Sun and
the second-largest in the Solar System,
after Jupiter.
 It is a gas giant with an average radius of
about nine and a half times that of Earth
It has only one-eighth the average density
of Earth; however, with its larger volume,
Saturn is over 95 times more massive.
SATUR

11.  Uranus is the seventh planet from the Sun.
 Its name is a reference to the Greek god of the sky, Uranus,
who, according to Greek mythology, was the great-
grandfather of Ares, grandfather of Zeus and father of
Cronus.
 It has the third-largest planetary radius and fourth-largest
planetary mass in the Solar System.
 Uranus is the coldest planet in solar system .
 It is known as ice giant .
URANUS

12.  Neptune is the eighth planet from the Sun and the farthest
known solar planet.
 In the Solar System, it is the fourth-largest planet by
diameter, the third-most-massive planet, and the densest
giant planet.
 It is 17 times the mass of Earth, and slightly more massive
than its near-twin Uranus.
 It goes around the sun once every 165 years .
 It is known as ice giant .
NEPTUNE

13.  An object in space that looks like a bright star with a tail
and that moves around the sun .
 Comets are also leftover from when the universe was
mode.
 All comets that have nucleus ,that is the ice , dust , and
rock in the comet.
 When the comet approaches the sun , the solar energy
melts the ice and vaporize . The gas form the comet make
the tail
COMETS

14.  Asteroids are small, rocky objects that
orbit the Sun.
 Although asteroids orbit the Sun like
planets, they are much smaller than planets.
 There are lots of asteroids in our solar
system.
 Most of them are located in the main
asteroid belt – a region between the orbits of
Mars and Jupiter.
ASTEROIDS

15.  A meteoroid is a small rocky or metallic body in
outer space.
 Meteoroids are significantly smaller than asteroids,
and range in size from small grains to one-meter-
wide objects.
 Objects smaller than this are classified as
micrometeoroids or space dust.
METEOROID

16.  A meteor is a space rock—or meteoroid—that enters Earth's
atmosphere.
 As the space rock falls toward Earth, the resistance—or drag—
of the air on the rock makes it extremely hot .
 It is also called a shooting star.
