Say Barry, could you abuse the answer-your-own-question feature of this site, and answer the following question:
As noted in How many constellations in the Zodiac? the ecliptic itself touches 13 constellations, but the Encylopedia Brittanica defines the Zodiac as "a belt around the heavens extending 9 [degrees] on either side of the ecliptic":
The Old Farmer's Almanac for 2014 (and previous years) notes (page 114) that Moon occasionally crosses into 5 "non-Zodiac" constellations at times:
So, exactly which constellations are "in the Zodiac" if the Zodiac extends 9 degrees on either side of the ecliptic?
And why 9 degrees? I know Venus can be as much as 8.25 degrees from the ecliptic,
