The Solar System ● The solar system includes:
○ 8 planets ○ 5 dwarf planets○ Moons○ Comets ○ Asteroids○
Meteors
-
Terrestrial Planets● Terrestrial Planets: planets made of rock
and metal● Mercury, Venus, Earth Mars
-
Gas Giants/Ice Giants● Gas Giants: planets that are made up of
mostly gas● Jupiter, Saturn, Uranus, Neptune

Comparing Planets to Earth● Temperature: Average temperature
60°F● Lithosphere: made of rock and metal
○ Creates a magnetic field to protect it● Atmosphere: thick but
not too thick
○ Mostly nitrogen and oxygen● Hydrosphere: water found in solid,
liquid and gas
states● Biosphere: life is

Mercury● Temperature: Day 800°F, night -300°F● Lithosphere:
rocky with no magnetic field to protect it● Atmosphere: no real
atmosphere
○ Surface is cratered like the moon● Hydrosphere: too hot and
too cold for liquid water to
exist● Biosphere: no life

Venus● Temperature: Average temperature 860°F● Lithosphere:
volcanic activity but no magnetic field● Atmosphere: 90X thicker
than Earth’s, mostly
greenhouse gases● Hydrosphere: too hot for liquid water to
exist● Biosphere: no life

Mars● Temperature: -90°F to 70°F● Lithosphere: rocky with past
signs of liquid water
○ No magnetic field to protect it● Atmosphere: very thin, mostly
carbon dioxide● Hydrosphere: frozen water ice at the poles●
Biosphere: no life

Jupiter● Temperature: Average temperature -230°F ● Lithosphere:
no solid surface, liquid at the center
○ Has a very large magnetic field● Atmosphere: very thick●
mostly hydrogen and helium● Hydrosphere: trace amount of water
vapor in the
atmosphere● Biosphere: no life

solid surface?
○ Very large magnetic field● Atmosphere: very thick● Mostly
hydrogen and helium● Hydrosphere: trace amounts of water vapor
in
atmosphere● Biosphere: no life
