meaning the month the sun is in a particular constellation ....can the moon be found to be full moon in a certain constallation in relation to the sun, etc??
why and how so for this?
the moon is a full moon usually when in the month?
Thanks for your answers!
I |||There is no special relationship. The sun's position is related very closely to the time of year. The moon's position is related very closely to the time of the lunar month. These are not related to each other, except by accident.
In other words, no matter where the sun is, the moon could be anywhere in its orbit. And vice versa.
Solar (sidereal) year = 365.25636042 days
Lunar (sidereal) month = 27.321661547 days
Ratios:
160 years = 2139 months (approx., with error of 0.39 hours)
19 years = 254 months (approx., with error of 4.05 hours)
8 years = 107 months (approx., with error of 32.81 hours)
|||There's somewhat of a relationship, especially if you count Ophiuchus as one of *13* Zodiacal constellations. There are about 13 lunar cycles a year, so the moon and sun will be *about* one constellation farther east than the month before for any given phase. The exact positions of the sun during particular moon phases will change from year to year since there aren't exactly 13 lunar cycles per year.
(Note, the moon's cycle of phases, the synodic month, is 29.5 days. The sidereal month is 27.3 days. So contrary to popular belief, neither of these is 28 days.)
Edit: Apparently Morningfoxnorth and I interpreted your question differently. As far as your question about when the moon is full, this does change by a day or so every month. But there is no way to know what phase or constellation the moon will be in during any particular month unless you note where it is when you start predicting. For example, the first quarter moon is in Aquarius this month; next month it will be in or near Pisces, and the month after that, Aries.|||The moon orbits the earth once every 28 days ! It has no bearing on which constellation thE sun is in !
