Q1:  (2 * 10^1000) * (5 * 10^1000) / 100 
   = (2 * 5) * (10^1000 * 10^1000) /100
   =  (10)    * (10^2000) /100
   =  (10^1 * 10^2000 * 10^-2)
   =  10^1999
   
Q2: Picture of Elliptical orbit - something like this if you can
imagine rounding out the corners and making all straight lines curved!
The Sun is off center by Kepler's first law.

                ----------------------
               /                      \
  Winter      |                  Sun   |   Summer
               \                      /
                ----------------------

Summer for Mercury occurs when the planet is closest to the Sun. By
Kepler's 2nd law, the planet moves fastest (equal area in equal times)
at this location. It moves slowest at its most distant point from the
Sun. So summer on Mercury is shorter than winter.

Q1: (3 * 10^1000) * (3 * 10^2000) / 300
  = (3 * 3 / 3)   * (10^1000 * 10^2000) / 100
  =    3          * 10^3000 /100
  =   3           * 10^2998
