The shaddow part of the moon

[rogerg (Roger)]

OK, really dumb question ...

Is there any fancy name for the part of the moon that's visible from earth and in shaddow?

Not the "dark side of the moon" but the bit we can see which is in shaddow.

[iceman (Mike)]

The "unlit" part?

[erick (Eric)]

"sub-terminator"? "moon night"?

"Nicta" is Greek for night.

The back of the moon is more appealing to me for astrophotography, but not for looking at or prettiness.

So how come we got the prettier face of the Moon facing the Earth - who arranged that? Seriously, why so few maria on the far side?

OK, I did a bit of Wikipedia searching:-

"The two hemispheres have distinctly different appearances, with the near side covered in multiple, large maria (Latin for 'seas,' since the earliest astronomers thought, wrongly, that these plains were seas of lunar water). The far side has a battered, densely cratered appearance with few maria. Only 2.5% of the surface of the far side is covered by maria,[1] compared to 31.2% on the near side. The most likely explanation for this difference is related to a higher concentration of heat-producing elements on the near-side hemisphere, as has been demonstrated by geochemical maps obtained from the Lunar Prospector gamma-ray spectrometer. While other factors such as surface elevation and crustal thickness could also affect where basalts erupt, these do not explain why the farside South Pole-Aitken basin (which contains the lowest elevations of the Moon and possesses a thin crust) was not as volcanically active as Oceanus Procellarum on the near side (for a more detailed discussion, see Lunar mare)."

So, there it is - we don't really know - that doesn't surprise me.

OK, 'nicta' it is then.

Now we need to know the fancy name for the far side of the moon!

Oh, and to save time, what's the 'lit' side called?

Intense sunburn country?

The blackout side?

Well, nobody's come up with anything , so I did some latinating.

How about:

'Lunalux' or 'luxa' - the bright bit

'Lunaversus' or 'versa' - the averted bit

To continue on that...

I personally reckon the larger % of maria on our side compared to the other side is due our side to having less exposure to the 'wild'. Our side of the moon is relatively protected by Earth where as the far side is an open plater for what ever is out there - potentially saving Earth from impacts? (as we do for our side of the moon???)

What do you guys think?

[erick (Eric)]

The "circle the wagons" for protection theory?

[Comet Hunter]

Yeah, I guess you could call it that (never heard that before - being a young whipper snapper and all )

[Richard F]

i have heard some people refer to it as "Earthshine"...
also i think Leonardo DaVinci refered to it as "ashen light"...
but i prefer Pink Floyd's name for it...
(...even if it isn't quite astronomically correct.)
