THE INNER AND OUTER PLANETS
SNC 1D
The Inner Planets
Terrestrial Rocky iron core High temperatures Closer to the Sun Closer to each other Smaller than the outer planets Slow rotation and fast revolution Few moons and no rings
Mercury
Closest to the Sun Rotation: 59days Revolution: 88days Very Thin
Atmosphere: Helium, oxygen, hydrogen
Many craters Temperature
extremes 400°C during day, -
180°C at night
Mercury
Venus
Earth’s sister planet Rotation: 243 days Revolution: 225 days Thick Atmosphere: mostly
carbon dioxide, nitrogen and sulfuric acid
Longer day than year Spins opposite than other
planets Over 500°C all the time Cratered and volcanic surface
Venus
Earth Home sweet home Only planet with
sustained life Hydrosphere
(water) Atmosphere made
up of N2, O2, CO2 Rotation: 24 hours
Revolution: 365 days
1 moon
Earth’s Moon
The moon makes a complete orbit around Earth in 27 Earth days and rotates or spins at that same rate, or in that same amount of time. This causes the moon to keep the same side or face towards Earth during the course of its orbit.
rocky, solid-surface
very thin atmosphere
Mars Frozen polar CO2
caps Smaller than Earth Rotation: Slightly
longer than 24 hours
Revolution: 687 days
Very cold Largest mountain
in solar system Olympus Mons
Thin atmosphere of CO2, N2 and Ar
2 moons:Phobos and Deimos
known as the Red Planet due to rust in soil
Moons of Mars
Phobos orbits Mars three
times a day very close to surface
Deimos smaller of Mars'
two moons whirls around Mars
every 30 hours.
