Material and compositions of moons sam e.

 The Moon
 The Earth’s 1st and only Moon
 Titan
 The 15th Moon of Saturn
 Phobos
 Mars’s second moon

 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

 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

 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

 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

 The Middle Core is Liquid
 The Middle Core consists of
○ Iron

 The Inner Core is solid
 The Inner Core is mainly solid because of
how cold the moon is
 The Inner Core consists of
○ Iron

 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

 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

 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

 Titan’s second layer consists of liquid
hydrogen
 The temperature of Liquid Hydrogen is
between -200°C and -258°C

 Titan’s third layer is water
 Water consists of
○ 66.6∞ Hydrogen
○ 33.3∞ Oxygen

 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

 Titan’s Core consists of Silicate
 Silicate consists of
○ 80% Oxygen
○ 20% Silicon

 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

 Phobos consists of a C-type rock similar
to the blackish carbonaceous chondrite
asteroids

 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

 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
