Atmospheres

Mercury

• Sodium, potassium and oxygen have been detected
  in Mercury's very weak atmosphere, but these
  elements can be lost when they react with the Sun
  and Mercury's magnetic field.
• Temperatures at the surface range between -300
  and 800 o F (hot enough for lead to melt) large
  range in surface temperature is possible because
  Mercury is so close to the Sun (a year is only 88
  Earth days long) and does not have sufficient
  atmosphere present to moderate the range in
  surface temperature.

Venus

• composed mostly of carbon dioxide which causes
  the...
• greenhouse effect which makes 400 degrees to over
  740 K (hot enough to melt lead).

Earth

5
Mars

• carbon dioxide (95.3) plus nitrogen (2.7),
  argon (1.6) and traces of oxygen (0.15) and
  water (0.03).
• very strong winds and vast dust storms that on
  occasion engulf the entire planet for months

6
Jupiter

• 90 hydrogen and 10 helium
• traces of methane, water, ammonia and "rock".
• Three distinct layers of clouds are believed to
  exist consisting of ammonia ice, ammonium
  hydrosulfide and a mixture of ice and water
• vivid colors seen in Jupiter's clouds are
  probably the result of subtle chemical reactions
  of the trace elements in Jupiter's atmosphere,
  perhaps involving sulfur whose compounds take on
  a wide variety of colors, but the details are
  unknown

7
Saturn

• Saturn appears less dramatic in color than
  Jupiter because of its increased sulfur content,
  which gives a yellow color
• Saturn is about 75 hydrogen and 25 helium with
  traces of water, methane, ammonia and "rock
• just as fierce as Jupiters atmosphere

8
Uranus

• Uranus' atmosphere is about 83 hydrogen, 15
  helium and 2 methane.
• Uranus has bands of clouds that blow around
  rapidly
• Uranus' blue color is the result of absorption of
  red light by methane in the upper atmosphere.

9
Neptune

• Neptune's blue color is the result of absorption
  of red light by methane in the atmosphere
• Neptunes atmosphere is mostly hydrogen and
  helium with a small amount of methane.
• Neptune's winds are the fastest in the solar
  system, reaching 2000 km/hour.

10
Pluto

• Plutos surface temperature is not well known but
  is probably between 35 and 45 Kelvins (-228 to
  -238 C).
• Ices on Pluto's surface evaporate and form an
  atmosphere
• Probably consists primarily of nitrogen with some
  carbon monoxide and methane

Planetary Composition

• Terrestrial
• Composed primarily of rock and metal and have
  relatively high densities, slow rotation, solid
  surfaces, no rings, and few satellites.
• Mercury, Venus, Earth and Mars

• Jovian
• Composed primarily of hydrogen and generally have
  low densities, rapid rotation, deep atmospheres,
  rings, and lots of satellites
• Jupiter, Saturn, Uranus, and Neptune
