The International Astronomical Union is the organization which defines the boundaries for the 88 constellations, not NASA. There are 13 constellations which the ecliptic crosses. This doesn't count all the other ones the moon and planets can pass through since they can be north or south of the ecliptic. Also, astrological definitions of the zodiac has drifted considerably from the astronomical locations of their constellations and astrology uses a standard 30° while the real constellations vary.

This doesn’t count all the other ones the moon and planets can pass through since they can be north or south of the ecliptic

********************

How does one ascertain north or south in space? North or south relative to what?

Ophiuchus? O-fuch-us? Now that right there is FUBAR!

Hmm. Ophiuchus, the serpent. Serpent - Satan - Allah. More NASA - Muslim outreach, I guess.
