7. 7.2 Members of Solar
System
 divide by formation and the
elements in 4 region
1. Inner planets
2. Asteroid belt
3. Outer planets
4. Oort’s cloud

8. 1. Inner planets
 The terrestrial planets
 Between the Sun and Asteroid belt
 Mercury, Venus, Earth ,Mars
 The planets that are small and
rocky, Metal Core.

9. 2. asteroid belt
 Most asteroids lie between the
orbits of Mars and Jupiter.
 An asteroid is a small, rocky body
whose diameter can range from a
few hundred kilometers to less than
a kilometer.
 Example : Gaspra, Ceres, Pallas

11. 3. Outer planets Giant
planets, The Jovian planets)
 The Giant planets, with huge gas ,
Hydrogen and Helium.
 Jupiter, Saturn, Uranus, and
Neptune.

12. 4. Oort’s cloud
 The Oort’s cloud are comets with
long orbital periods appear to be
distributed in all directions from the
sun, forming a spherical shell
around the solar system

15. Meteoroid
 A meteoroid is a small, solid
particle that travels through space.
 A meteor is the luminous
phenomenon observed when a
meteoroid enters Earth’s
atmosphere and burns up,
popularly called a shooting star
 A meteorite( ) is any

16. Comet’s Tail Points Away from the Sun

17. Kuiper belt object
 Like the asteroids in the inner solar
system
 Most Kuiper belt comets move in
nearly circular orbits that lie
roughly in the same plane as the
planets
 Example Objects : Pluto , Eris

20. 7.3 The Sun
 The Sun is informally designated as
a yellow dwarf, based on spectral
class, is G2
 surface temperature of
approximately 5778 K (5505 C)
 It has a diameter of about
1,392,684 km about 109 times that
of Earth
30

21.  The Sun device into 2 part
 1. the Solar Interior.
 2. Atmospheric Layers.

22. The Solar Interior :
divide into 3 layer
 1. Core : A temperature of
Core close to 15.7 million kelvin.
Energy is produced by nuclear
fusion.
 2. Radiation zone
 3. Convection zone

24. Atmospheric layers : divide
into 3 layer
 1. photosphere
5,800
 2. chromosphere
25,000
 3. corona
