2. The Moon
The Earth’s 1st and only Moon
Titan
The 15th Moon of Saturn
Phobos
Mars’s second moon
3. Our Moon has Five Layers
The Top Layer is the Crust
The 2nd Layer is the Mantle
The 3rd Layer is the Outer Core
The 4th Layer is the Liquid Core
The 5th Layer is the Solid inner Core
4. The Crust is the surface of the Moon
It consists of regolith and hardened lava
Regolith consists of:
40% Oxygen
20% Silicon
12% Iron
8.5% Calcium
7.3% Aluminum
4.8% Magnesium
4.5% Titanium
0.33% Sodium
0.2% Chromium
0.16%Manganese
0.11% Potassium
540 ppm Sulfur
200 ppm Carbon
100 ppm Nitrogen
40 ppm Hydrogen
428ppm Helium
5. The Mantle is the inside of the Moon that is
not the Core
The Mantle contains
○ Some olivine
○ some orthopyroxene
○ It is also richer in iron then earth
6. All parts of the Core consist of the same
thing
The Outer Core is a state that is
somewhat Fluid state
The Outer Core consists of
○ Iron
○ Some other metals
7. The Middle Core is Liquid
The Middle Core consists of
○ Iron
○ Some other metals
8. The Inner Core is solid
The Inner Core is mainly solid because of
how cold the moon is
The Inner Core consists of
○ Iron
○ Some other metals
9. The Moon is 238,900 miles from Earth
The Moon’s day is 27.3 Earth days
The temperature of the moon is between
-170 to 110 °C
There are 1,500 Moonquakes every
year
The Moon also drifts one centimeter
away from Earth every year
10. The Moon
The Earth’s 1st and only Moon
Titan
The 15th Moon of Saturn
Phobos
Mars’s second moon
11. The first layer of Titan is the Atmosphere
The second layer of Titan is frozen liquid
Hydrogen
The third layer is Liquid water
The fourth layer is high-
pressure ice
The fifth layer is the Silicate
Core
12. Titan’s Atmosphere is so thick that it
prevented us from learning about Titan’s
surface for a while
Something unknown is recycling
methane in Titan’s Atmosphere
13. Titan’s second layer consists of liquid
hydrogen
The temperature of Liquid Hydrogen is
between -200°C and -258°C
14. Titan’s third layer is water
Water consists of
○ 66.6∞ Hydrogen
○ 33.3∞ Oxygen
15. The Fourth layer is high pressure ice
High pressure ice is gas that is put under so
much pressure that it behaves like a solid
○ It consists of
Methane
16. Titan’s Core consists of Silicate
Silicate consists of
○ 80% Oxygen
○ 20% Silicon
17. It originally thought the biggest moon in the solar
system
The surface pressure of Titan would feel like the
bottom of a swimming pool
Titan is larger than Mercury
Titan has many lakes and mountains like Earth
Titan is 3,200 miles wide
In 1655 Christiaan Huygens Discovered Titan
Titans atmosphere is 124 miles deep
Titan is the second biggest moon in our solar
system
18. The Moon
The Earth’s 1st and only Moon
Titan
The 15th Moon of Saturn
Phobos
Mars’s second moon
19. Phobos consists of a C-type rock similar
to the blackish carbonaceous chondrite
asteroids
20. Phobos surface is basically dust
because it has been hit by thousands of
asteroids
One of the most prominent features is
the 6 mile wide Stickney crater
21. It orbits Mars three times a day
Phobos has no atmosphere
Asaph Hall discovered Phobos on August
17th, 1877
Asaph named Phobos, Phobos for the son
of Ares, the Greek counterpart of the
Roman god, Mars
Phobos means fear or panic
Every one-hundred years Phobos drifts 1.8
miles closer to Mars
