The following plots show the positions of planets projected on to the ecliptic at 1 month intervals. Planetary data were read from the Jet Propulsion Laboratory's ephemeris DE406 using the NAIF SPICE toolkit and the plots were made using PGPLOT.

The colours used are yellow (Sun), brown (Mercury), green (Venus), blue (Earth), red (Mars), orange (Jupiter), grey (Saturn), pink (Uranus) and purple (Neptune). The first point of Aries (the direction of the Sun as viewed from the Earth at the time of the northern vernal equinox) is towards the right. Relative sizes of Sun and planets are not to scale.
