The Crusade

From  Mars to Jupiter



Next Page

  A circle is drawn to represent Jupiter's orbit. Four touching circles drawn with centres on this circle leave a space in the middle which can be taken to represent Mars's mean orbit with over 99.9% accuracy. Four touching circles can also be used to accurately space Chiron from Mars when viewed from Earth (not shown but do try it at home). An alternative and much neater way of drawing the two orbits is shown reduced in the bottom right hand corner. Jupiter rules expansion and Mars is characterised by acts of will; as long as there is a good structure to the expansion, normally provided by Saturn, and here symbolised by the square, then this is the stuff of which empires are built.
