Mars: A Close Approach and Retrograde Motion of Planets

Figure 1

In 2018, Mars will appear brightest from July 27 to July 30. Its closest approach to Earth is July 31. That is the point in Mars' orbit when it comes closest to Earth. Mars will be at a distance of 57.6 million kilometres ... In 2003, Mars made its closest approach to Earth in nearly 60,000 years! It won't be that close again until the year 2287. Source.

Of course, Astrology doesn't take these close encounters of Mars or any other planet into account at all. The astrological chart is only concerned with a planet's celestial longitude or the angular distance of a planet east of the vernal equinox, measured along the ecliptic. Thus on July 31st at 4:33pm in Brisbane, Mars was in 3°02' of Aquarius or 303°02' east of the vernal equinox. It's celestial latitude was 6°33' South but this is not considered in chart analysis as far as I know.

Should the proximity of Mars to Earth be considered in chart analysis? Will Mars be more influential in the charts of persons who were born on July 31st 2018 compared with charts where Mars is at a maximum distance from Earth? Is a transit of Mars more powerful when it is closer to Earth than when it is farther away? I really don't know. However, what is known is that Mars is opposition to the Sun during such encounters and there is always period of time in which Mars appears to move backward through the zodiac because Earth is "overtaking" Mars because of the latter's slower orbital velocity. Mars is retrograde in Aquarius and Capricorn from June 26th to August 27th, 2018. Figure 2 shows this.

In general, Mars is retrograde approximately 58-81 days every 2+ years. Cafe Astrology. com makes the following observation about a retrograde Mars in the natal chart:

If Mars is retrograde in the natal chart, this is what the Karmic Insight report has to say about this position: “Asserting yourself vigorously and directly is complicated by the fact that you had a prior lifetime or lifetimes in which aggression was either misused (by you, or against you) and/or all personal initiative and self-will was insistently discouraged (perhaps due to a belief system that advocated passivity). 

In any case, the message that was impressed upon you was that forceful action is wrong or dangerous. Thus, if you stand up for yourself, you now tend to hesitate, back down or even be plagued with fears of retaliation.”

Most natal charts will thus not have Mars retrograde. In 90% or more of natal charts, Mars will be in direct motion. This got me thinking about the periods of retrograde motion of other planets. Cafe Astrology. com has a lot to say about Mercury retrograde, a phenomenon that occurs approximately three times a year for approximately three weeks each time. Here is a quick quote:

When Mercury is retrograde in the natal chart itself, the thinking processes are generally more acute, and the sense of humour rather quirky. People with Mercury retrograde take in information differently than those with Mercury direct in their natal charts. How many people are born with a retrograde Mercury? Roughly 18%. 

Venus appears to retrograde approximately 40-43 days out of every 18 months or around 7-8% of its orbit.  How does a retrograde Venus affect a natal chart? Again Cafe Astrology. com has a lot to say about this. Here is an excerpt:

When Venus is retrograde in the natal chart itself, the feeling nature is deep. Socialising is taken seriously, and rarely lightly. They can be somewhat shy in youth, as there can be an awkwardness felt concerning small talk and social graces, and an aversion for superficialities. Love is extremely important to a person with a retrograde Venus, but they may not be explicit about it enough for others to know just how deeply they can love. There is always more to this person than meets the eye. Their love life (and sometimes financial life) can be hidden in some manner.

Cafe Astrology.com has a page about retrograde motion in general in which the point is made that as we move further out with the planets, retrogrades occur more frequently, and it is more common for people to have these planets retrograde in their charts. There follows descriptions for Jupiter, Saturn, Uranus, Neptune and Pluto in retrograde motion, although no percentages for the amount of time spent retrograde. However, I discovered the following summary on Quora:

Planet --> Synodic period, days --> Synodic period, mean months --> Days in retrograde -->  %

Mercury --> 116 --> 3.8 -->   ~21 -->   18
Venus --> 584 --> 19.2 -->    41  -->     7
Mars --> 780 --> 25.6 -->     72 -->      9
Jupiter --> 399 --> 13.1 -->  121  -->    30
Saturn --> 378 --> 12.4 -->   138  -->    37
Uranus --> 370 --> 12.15 -->   151 -->    41
Neptune --> 367 --> 12.07 -->   158  -->    43

Pluto of course would be even closer to 50%. The table clearly shows that persons with Mercury, Venus and Mars retrograde are in a distinct minority and that it should be a factor to consider when interpreting natal charts.
