Graph

• Orbits
  • Mercury in yellow
  • For reference a circular orbit with the same semi-major axis in grey

• The orbit plotted in brighter colours above the ecliptic and darker below.
• Major axis drawn showing perihelion (q) and aphelion (Q)
• Mercury
  • Positions show every 5 days before and after the perihelion on May 20, 2006
  • For illustration the size of the sphere is inversley proportional to the distance from the Sun.
• Orientation
  • The Sun in the center.
  • Yellow segment points toward the vernal point.
  • View from the above the ecliptic (North Pole)
