A
  Survey Of The Planets
  Web-based Assignment: Fill
  In The Summary Graph
  
Using the "Summary Table" you have
filled in, plot the requested information on the following "Summary Graphs".
  To do so, follow the steps: 
  - For the first graph (upper left hand corner), plot
    the mass of each planet versus its distance from the Sun.  To do so, you will have to
    decide how to mark each axis so that all of the planetary data will fit.  You must
    also decide how to express both the mass and the distance (may I suggest mass in
    comparison to the Earth, and distance in astronomical units?).  The goal is to see
    how mass varies as you move out in the Solar System.  Does the mass of a planet
    increase steadily, decrease steadily or clump in different regions of the Solar System?
  - For the second graph (upper right hand corner),
    plot the radius of each planet versus its distance from the Sun.  To do so, you will
    have to decide how to mark each axis so that all of the planetary data will fit.  You
    must also decide how to express both the radius and the distance (again, may I suggest
    radius in comparison to the Earth, and distance in astronomical units?).  The goal is
    to see how radius varies as you move out in the Solar System.  Does the radius of a
    planet increase steadily, decrease steadily or clump in different regions of the Solar
    System?
  - For the third graph (middle left hand corner),
    plot the density of each planet versus its distance from the Sun.  Again  you
    must also decide how to express both the density and the distance (may I suggest density
    in grams/cm3, and distance in astronomical
    units?).  Be sure all the data fit on the graph!  The goal is to see how density
    varies as you move out in the Solar System. 
  - For the fourth graph (middle right hand corner),
    plot the temperature of each planet versus its distance from the Sun.  Again, you
    must also decide how to express both the temperature and the distance, and be sure that
    all the planets fit on the graph.  The goal is to see how temperature varies as you
    move out in the Solar System.
  - For the fifth graph (lower left hand corner), plot
    the orbital eccentricity of each planet versus its distance from the Sun.  Again, you
    must also decide how to express both the eccentricity and the distance, and be sure that
    all the planets fit on the graph.  The goal is to see how orbital eccentricity varies
    as you move out in the Solar System.
  - Finally, for the fifth graph (lower right hand
    corner), plot the orbital inclination of each planet versus its distance from the Sun.
      The goal is to see how orbital inclination varies as you move out in the Solar
    System.
After you have
plotted the data, look it over and see what overall trends become apparent for planets in
the Solar System.  With a little thought, you should begin to see patterns that need
to be explained by theories of Solar System formation.
Can you devise
your own theory as to why the planetary properties are as they are?   
Can  you
make predictions about how other solar systems, around other stars should appear?
