Think before you type. Alot of people see the moon in the day. Full moon, while heavily linked to romance in our western culture, is not the
beginning or end-all but rather a mid-point in the moon's monthly orbit. Sunsets are another time that people are out in the western world looking
and that would be a good time to spot the crescent moon. As far as the part of the world facing away from the sun and the part facing the sun being
seasonal - I think not...I think you're talking about day and night. It happens.
Actually, a full moon is a mid point in the monthly phases
of the moon, not necessarily a midpoint in its orbit. The phase of the moon is
dependent on the relative positions of the observer on Earth and the sun at that time of year when compared to the moon's current position in its
orbit around Earth.
The seasons are mostly caused by the Earth's tilt.
Mostly? Be assured that they are caused by the earths' tilt. Here's a link to some long...really long...cycles that supposedly influence the seasons
as well. We won't live to see these differences but I guess we can theorize about them and think about how they may affect us. What we're talking
about here in this thread though seems to be something a little bit more abrupt.
(orbital distance and amount of landmass on the northern hemisphere that causes the north to experience more variant seasons than the southern),
Distance I know about but landmass I don't as far as a relationship to seasons. Please tell me more.
Yes, it is -mostly- caused by the Earth's tilt..because the Earth is actually further away from the sun during the northern summer than it is in
winter. Really not going to argue semantics on that one though.
And not to further derail, but yes, landmass is a factor in the seasons because the northern hemisphere has a lot more landmass than the southern and
rocks, dirt, etc (aka 'land') is going to have a much more variant temperature between winter and summer than the oceans. There's an animation out
there on wiki that shows the seasonal progression and it's pretty easy to notice the difference, but this is not really on topic so I leave that to
you to go look if you really are wanting to know more about it.
So as we've been saying, during the winter, the moon as viewed at night on Earth is going to follow the same general path through the sky as the sun
does in summer
The moon follows the same path as the sun day and night, month after month with a variance of 5 degrees either side spread out over an 18.6 year
The moon is monthly, it is not seasonal. It varies 5 degrees from the suns' path over an 18.6 year cycle wherein it reaches maximum and minimum
variance called lunar standstills and sometimes equated to the yearly solstices and equinoxes of the sun.
This is the part we've been trying to explain to you that you are either failing to understand or are willfully continuing on despite being wrong.
Yes, the moon does indeed follow the same path in its orbit regardless of what season it is. The thing that you're missing is that the Earth's tilt
causes the path of the ecliptic in the night sky...which is where the moon's orbit lies (the whole variance of 5 degrees on the 18.6 year cycle is to
the ecliptic), to change position in the sky to an observer on Earth over the course of a 24hr period because of the Earth's tilt. Over the course
of a year, the position of the ecliptic in the day and night side of the planet will switch due to the Earth being on the opposite side of the sun.
During winter we are tilted away from the sun, which means all objects which orbit along the ecliptic will appear higher in the sky at night
an observer on the northern hemisphere. Conversely, things visible during the day to an observer will appear lower during the day. That means, the
planets, constellations of the zodiac, moon, etc.
In order for the moon to retain the same positions in the night sky throughout the year would require it to have an orbit that shifted on a yearly
cycle...which it does not do and even you have said this over and over again.
The moon being visible during the day has nothing to do with your cheshire/boat/etc moon as that moon occurs at night, so I see no point in really
bringing that into this - suffice to say I never said it wasn't visible during the day.
If you can draw a straight line from where the sun would be (below the horizon) through the boat moon to one of the constellations of the
zodiac...I'll give you a guess what that means - and it's certainly not that there's something wrong with the moon.
