I like to share here link to this great article :
The Astronomy and Astrology of Jupiter
Earth-Jupiter Synodic Cycles,
Astrophysical Jupiter, Jupiter’s Orbital Cross,
& Jupiter’s Astrological Nature
Here are some parts of it that I find very interesting but I recomend you read it in the link and see all charts.
Jupiter’s Orbital Cross
Jupiter’s greatest influence on the Sun & Earth
Jupiter’s greatest magnetic influence on the Sun occurs when Jupiter is at its perihelion (Jupiter’s closest point to the Sun during its orbit). Jupiter’s greatest influence on Earth occurs when Earth and Jupiter align (the Earth-Jupiter synods) during Jupiter’s perihelions. These Synodic Cycles are thus more influential then those occurring during Jupiter’s aphelions.
Jupiter’s orbital positions also effect sunspot activity as do those of Saturn. The interactive orbits of Jupiter and Saturn also synchronize with solar cycle activity; and hence Earth’s geophysical activity and climate fluctuations–a topic of its own.
Astrologers might consider that people born during the peak influences (shown in gold bands in the illustration below) may have a greater Sun-Jupiter resonance as well as a stronger Earth-Jupiter synodic theme into which they were born. If a person is born very near a synod occurring during a perihelion, Jupiter’s influence may be extra significant.
Jupiter’s Perihelion 19° 28′ sidereal Pisces (01S18); Sun-Jupiter Distance 4.95… AU.
Sep 21, 2010 Synod – Earth-Jupiter Distance: 3.95393 AU
Oct 29, 2011 Synod – Earth-Jupiter Distance: 3.96975 AU
Sep 26, 2022 Synod – Earth-Jupiter Distance: 3.95256 AU
Nov 03, 2023 Synod – Earth-Jupiter Distance: 3.98237 AU
The Earth-Jupiter synodic cycles of September 21, 2010 and October 29, 2011 occur during Jupiter’s 2011 perihelion and thus are emphasized; as is the new 13.5-year Jupiter-Uranus synodic cycle starting on Sept 23, 2010.
The September 21, 2010 synod produces the closest Earth-Jupiter distance in our current (2011) perihelion window, with next occurring in September of 2022. The September 21, 2010 synod is also extra significant due to the synchronization with the new 13.5-year Jupiter-Uranus synod. Thus, the Earth-Jupiter synodic cycles starting with the September 21, 2010 Synod nest in the new 13.5-year Jupiter-Uranus synodic cycle theme.
