2. OBJECTIVES
 THE OUTER PLANETS ARE JUPITER,
SATURN,URANUS, NEPTUNE, PLUTO.
 JUPITER, SATURN, URANUS, AND NEPTUNE
(ALSO CALLED THE JOVIAN PLANETS) ARE
MUCH LARGER THAN THE EARTH
 THE ARE RICH IN HYDROGEN GAS AND/OR
ITS COMPOUNDS, SUCH AS WATER,
METHANE,AND AMMONIA.

3. ………………………….
 THEY HAVE DEEP, THICK ATMOSPHERES
AND NO SOLID SURFACE.
 THEY HAVE MANY MOONS AND RINGS.
 PLUTO IS FAR SMALLER AND HAS VERY
DIFFERENT STRUCTURE THAN OTHER OUTER
PLANETS. IT IS A MIX OF MAINLY ROCK AND
FROẒEN WATER.

6. Jupiter
 is the fifth planet from the Sun and the
largest planet in the Solar System.
 It is a gas giant with mass one-thousandth
that of the Sun but is two and a half times
the mass of all the other planets in the
Solar System combined.
 Jupiter is classified as a gas giant along
with Saturn, Uranus and Neptune.

7.  Together, these four planets are
sometimes referred to as the Jovian or
outer planets
 The Romans named the planet after
the Roman god Jupiter.
 Jupiter can reach unapparent
magnitude of −2.94, bright enough to cast
shadows

8.  Jupiter is primarily composed
of hydrogen with a quarter of its mass
being helium.
 It may also have a rocky core of heavier
elements, but like the other gas giants,
Jupiter lacks a well-defined solid surface.

9. Orbit and rotation
 Jupiter is the only planet that has a center of
mass with the Sun that lies outside the volume
of the Sun, though by only 7% of the Sun's
radius.
 The average distance between Jupiter and
the Sun is 778 million km
 There are also at least 67 moons, including the
four large moons called the Galilean
moons that were first discovered by Galileo
Galilei in 1610.

10. ORBIT AND ROTATION

11. Ganymede, the largest of these
moons, has a diameter greater
than that of the planet Mercury.

13. SATURN

14. SATURN
 is the sixth planet from the Sun and the
second largest planet in the Solar System,
after Jupiter.
 Saturn is a gas giant with an average radius
about nine times that Of Earth.
 Saturn's interior is probably composed of a
core of iron, nickel and rock, surrounded by a
deep layer of metallic hydrogen, an
intermediate layer of liquid
hydrogen and liquid helium and an outer
gaseous layer.

15.  The planet exhibits a pale yellow hue due to
ammonia crystals in its upper atmosphere.
 Sixty-two known moons orbit the planet; fifty-three
are officially named. This does not include the
hundreds of "moonlets" within the rings.
 Titan, Saturn's largest and the Solar System's second
largest moon, is larger than the planet Mercury and
is the only moon in the Solar System to retain a
substantial atmosphere.

16. Orbit and rotation
 The average distance between Saturn and
the Sun is over 1.4 billion kilometer's (9 AU).
 With an average orbital speed of 9.69 km/s, it
takes Saturn 10,759 Earth days (or about
29½ years), to finish one revolution around the
Sun.
 The elliptical orbit of Saturn is inclined 2.48°
relative to the orbital plane of the Earth.

17. Titan (or Saturn VI) is the
largest moon of Saturn.

19. URANUS

20. Uranus
 is the seventh planet from the Sun.
 It has the third-largest planetary radius and
fourth-largest planetary mass in the Solar
System.
 astronomers sometimes place them in a
separate category called "ice giants".
 Saturn's in its primary composition of hydrogen
and helium, contains more "ices" such as
water ,ammonia, and methane, along with
traces of hydrocarbons.

21.  It is the coldest planetary atmosphere in
the Solar System, with a minimum
temperature of 49 K .
 It is the only planet whose name is derived
from a figure from Greek mythology
 The wind speeds on Uranus can reach 250
meters per second (900 km/h, 560 mph).

22. ORBIT AND ROTATION
 Uranus revolves around the Sun once
every 84 Earth years. Its average distance
from the Sun is roughly 3 billion km (about
20 AU).
 The intensity of sunlight on Uranus is about
1/400 that on Earth.
 Its orbital elements were first calculated in
1783 by Pierre-Simon Laplace.

24. NEPTUNE

25. Neptune
 is the eighth and farthest planet from
the Sun in the Solar System.
 It is the fourth-largest planet by diameter
and the third-largest by mass.
 Among the gaseous planets in the solar
system, Neptune is the most dense.

26.  Neptune was the first planet found by
mathematical prediction rather than
by empirical observation.
 Neptune was subsequently observed on 23
September 1846
 its largest moon , Triton, was discovered
shortly thereafter, though none of the planet's
remaining 13 moons were located
telescopically until the 20th century.

27. Triton is the largest moon of
the planet Neptune

28. ORBIT AND ROTATION
 The average distance between Neptune
and the Sun is4.50 billion km (about
30.1 AU)
 It completes an orbit on average every
164.79 years, subject to a variability of
around ±0.1 years.
 The elliptical orbit of Neptune is inclined
1.77° compared to the Earth. Because of
an eccentricity of 0.011.

30. PLUTO

31. Pluto
 Pluto, formal designation 134340 Pluto, is
the second-most-massive known dwarf
planet in the Solar System(after Eris) and
the tenth-most-massive body observed
directly orbiting the Sun.
 Originally classified as the ninth
planet from the Sun.

32. PLUTO
 Pluto is composed primarily of rock and
ice and is relatively small, approximately
one-sixth the mass of the Earth's
Moon and one-third its volume.

33. NEW UPDATE OF PLUTO
 Pluto has been called "an oddball little
planet," "the misfit of the solar system",
and "an elusive outcast.“
 Pluto lies on what we consider the edge
of the solar system. Today, it's a neglected
little oddity in a too distant orbit.
Someday, it may be a busy spaceport,
gateway to the stars, and rich with tourist
dollars.
