I guess I was wondering how you used all these 26 variables. If the
code has specific planets hard-wired in at certain places, then having 
them as individual variables is one way to go. But do you ever do
things like iterate over them, or access them by name? If so, you
could look at structuring your data slightly differently. For example, 
you could keep a hash:

   planets = Hash.new

   for planet in 'a'..'a'
      planets[planet] = Planet.new(...)
   end

Without knowing your application, this is obviously just idle
speculation
