7. MERCURY
Mercury, one of the planets in the solar system.
Mercury orbits closest to the Sun of all the planets,
at an average distance of approximately 58 million
km. The surface temperature at noon reaches
400°C, while at night reaches 200°C.

8. Venus
Venus, one of the planets in the solar system, the second in
distance from the Sun. Except for the Sun and the Moon,
Venus is the brightest object in the sky. Venus Surface
temperature reaches 450°C, so there’s no water or sea.
Venus is often called East Star, Dawn Star, Morning Star
because sometimes it looks shiny in the east at sunrise
Venus is often called West Star, Evening Star, Night Star,
because sometimes it appears at Sunset in the west

9. Earth
Earth (planet), one of nine planets in the solar system, the
only planet known to harbor life, and the “home” of
human beings.
The Earth made up of several layer :
Earth’s Crust
Earth’s Mantle
Outer core of Earth
Inner core of Earth

10. Mars
Mars, one of the planets in the solar system, it is the
fourth planet from the Sun and orbits the Sun at an
average distance of about 228 million km (about 141
million mi), and the average temperature in Mars reaches
-60°C
Name of Mars comes from the god of War of Roman
people
Mars has the largest and highest mountain in the solar
system that’s Olympus Mons which is 27 km high and 600
km in diameter

11. Jupiter
Jupiter, fifth planet from the Sun and the largest planet in
the solar system, Jupiter’s diameter is about 143
thousand km or 11 times the earth’s diameter ( about
1300 times the earth’s diameter )
Jupiter is made up of dense gasses such as hydrogen and
helium. Jupiter’s surface is covered by a rotating gas
cloud, the temperature in upper part of Jupiter cloud is
about 140°C
Figure
12. Saturn
Saturn, sixth planet in order of distance from the Sun, and
the second largest in the solar system
Saturn has a ring that consist of collection of dust and
pebbles that’s covered by ice
Its Surface temperature reaches -176°C
Figure
13. Uranus
Uranus, Uranus was found by William Herschel, a British
astronomer on March 13th 1781. Seventh planet from the
Sun.
Uranus revolves outside the orbit of Saturn and inside the
orbit of Neptune
Uranus has a solid core that’s made up of metal and is
surrounded by the layers o gas and ice. Its temperature is
very cold (-241°C). Uranus looks navy blue
Figure
14. Neptune
Neptune, eighth planet from the Sun and fourth largest in
diameter.
Neptune was found in 1844 as a result of cooperation
between Leverier (French), Adams (English), and Galle
(Berlin/German).
The condition of Neptune is similar to Uranus so these
two planets are called twin planets the surface
temperature reaches -120°

Satellite is a celestial object that orbits a planet and
together with the planet revolves around the sun

17. Artificial Satellite
Artificial Satellite is a Satellite that is made by human and
designed to move in a path that has been determined and
serve a certain purpose
example : to collect and send data or information

18. Asteroid
Asteroid are celestial object that are smaller than planets,
they are made up of rocks and iron, and have diameters
ranging from several meters to hundreds of kilometers
Cluster of hundreds of thousands of asteroids called the
Asteroid Belt

19. Comet
Comet are celestial objects that revolves around the sun
forming an oval orbit.
Comet consist of a collection of freezing dust and
gasses, but if they pass close the sun, the will melt and
vaporize
Comet is often called a hairy star, because when the
comet moves, at the back part of it there’s a gas spurt like
a tail, the length can reach millions of kilometers and if
the comet near with the sun, its tail can be more long

20. meteor
Meteor are celestial objects that move at high velocity
entering Earth’s sky
When the meteor move to Earth’s surface, they cause friction
with the Earth’s atmosphere , the friction produce heat, so
meteor are burnt out completely
But there are also meteors that are not burnt out, so they
reach Earth’s Surface, called Falling Star
Meteor that enter the Earth’s Atmosphere called Meteoroid
Meteor that reach the Earth’s Surface called Meteorites
(in Arizona, has diameter 1.3 km the depth 175 m), this
Meteoric Crater is called Barriger Creater
