Summary
Description Venus pentagram.png |
English:
The planet
Venus
orbits just over 13 times for every 8 orbits of the
Earth
, creating a
pentagrammic
pattern of
inferior conjunctions
. Each successive inferior conjunction occurs after about 1.6 Earth years and therefore shifts about 144 degrees in the direction opposite the Earth's orbital motion. During each cycle of 8 Earth years, the pentagram
precesses
about 1.5 degrees in the direction of Earth's orbital motion, reflecting the fact that the Earth:Venus orbital ratio is an approximate ('near') rather than a perfect
orbital resonance
.

Date | 24 September 2007 Motion of planet venus over 5 successive inferior conjunctions follows a pentagram pattern, precessing 2/5 of an orbit between conjunctions. |
