Planets

Mercury

Synchronous Rotation
Fastest moving in its orbit (p^2=a^3)
No atmosphere
Geologically dead
-No volcanoes, tectonics etc.
The most eccentric orbit
Endured a monstrous impact

Venus

Hot, thick atmosphere
Retrograde motion
Almost the twin of Earth in size
Hottest surface in the solar system (900 degrees F)
Brightest Planet in the sky
SO4 acid rain , thick CO2 atmosphere
Active volcanoes
Roundest in orbit of all planets.

Earth

Only place with life (so far as we know)
An atmosphere of n2 and o2
-CO2 is more common
Active surface
-Plate tectonics, volcanoes
Oceans of liquid water
The densest planet

Mars

Famous for stories of life
-Canals on the surface
-War of the worlds
Largest volcanoes in solar system
largest conyon in solar system
Thin CO2 atmosphere
Hemisphere different
Very dry, but had water anciently
-A mystery

Jupiter

Largest planet in solar system
-2.5 times the mass of all the other planets, moons, etc. combined.
The largest storm (Great Red Spot)
Thing Ring
63 moons
Fastest rotation (9 hours 50 min)
Shortest day
~12 year orbit -> Chinese Symbols

Saturn

Similar in nature to Jupiter
-But colder which makes the belt zones less pronounced
lowest density-less than water
61 moons
spectacular set of rings

Uranus

Faint, seasonal cloud features
rotation axis tipped on its side (98 degrees)
Thin rings
offset magnetic field

Neptune

More structure in the atmosphere
Great Dark Spot
Fastest, strongest winds
Methane crystal clouds
coldest temperature
offset magnetic field again
