Hmm. In that case... Murphy's luminosity is 1/50th of the sun. Shadow orbits at about 0.06 AU.

L = (M/Msun)^3.9, converted to watts (Lsun = 3.9*10^26 W) and calculated for apparent brightness. b = L/(4*pi*r^2) where r is in meters. After getting the apparent brightness of Murphy from Shadow, I calculated the apparent brightness of the sun from earth to compare the two.

Murphy is 6 times as bright from Shadow as the sun is from earth. That's okay, because sky luminosity varies on earth by 10^-2 to 10^3 from dawn/dusk to midday. Midday, though, might not want to be out at midday. Unless Shadow happens to be a stormy place.

I had thought the power output of a Protostar was much reduced, perhaps I recall incorrectly. If so, the heat from Murphy would not be that unbearable, and the light would cause advanced photosythesis, greater fauna growth, more greenhouse effect, more filtering of the atmo to protect the surface from UV rays.
Remember the atmo processes have become controlled by man, so not as subject to climactic laws as we currently know them.
Also discussed previously, in the more appropriate thread, was the visual perception of light. Consider what you know of as "nightvision" and how lifeforms adapt to different light levels. If you live a life at one level of light, it will seem normal to you.

The energy output IS greatly reduced, and I stand by my calculations of energy output measured in Watts (luminosity). L = (M/Msun)^3.9 is a valid and commonly used astronomical calculation.

The key factor here is that Shadow is closer to Murphy than even Mercury is to our sun. Apparent brightness, or how much light/energy is received from a source, increases by a power of two with increasing proximity.

And I'm talking less so much about people needing special sunglasses (your comments in regards to vision) than I am talking about UV radiation. Maybe Shadow has an even thicker ozone layer than does earth, but like I said, wouldn't want to be out at midday. You'd get six times as bad a sunburn in 1/6th the time.

YOU CAN NOT TRAVEL FAST AS THE SPEED OF LIGHT E=MC2 WHITCH MEANS MASS TURNS INTO ENEERGE SO IF YOU HAVE A SHIP IT WOULD TURN IN TO LIGHT AND THAT INPOSSABULE NOW YOU CAN HAVE WARP ENEGENS THAT MOVE THE SPACE AROUND THE SHIP BUT NOT THE SHIP ITS SELF THEREFORE YOU COULD TRAVEL FASTER THEN THE SPEED OF LIGHT.

Hey, not so smart. Have you seen Firefly or Serenity? No craft reach or exceed the speed of light in this verse. One third of the speed of light is not more than the speed of light. There are no warp engines in this verse. Not FTL travel.
Get with the program. Since you are not so smart, but think you are, you should watch more than once or reread your material before trying to make claims without basis. The rest of us, geniuses included, already make enough mistakes, but at least we are actually trying.

I keep forgetting to answer this. So I am bumping it now, to answer when I check out the details (to explain correctly).

9 July 2015:
In the Core, Lux orbits White Sun at 30Au with 164 year duration. This is prograde, or ClockWise in our view of the Map. Persephone is the second orbiting body around Lux, at .037Au distance and 121 days duration, also CW. So every 121 days, Persephone is 30.037Au from White Sun.
Pelorum is the other orbital body of Lux, with 188 day duration.

Halo asteroid belt is at a distance of 40-43 Au from White Sun.

Georgia Sun system orbits White Sun at a distance of 68Au and 560.7 years duration. Also in prograde, which still looks like CW in our view of the Map.
Murphy orbits Georgia Sun at a distance of 16Au and duration of 64 years. Murphy is in retrograde, orbiting Georgia in CounterClockWise direction, which when closest to White Sun like in 2511 is moving CW in reference to White Sun, so almost parallel to Lux. When closest to White Sun, Murphy is 52Au from White Sun and 22Au from Lux in 2511.
Hera is the first orbital body of Murphy with a distance of .030Au and duration of 99 days. Hera looks to also orbit CCW, which would again look CW compared to White Sun when Hera is closest to White Sun (and farthest from Georgia Sun). So the closest Hera and Persephone can get in 2511 is about 21.033Au from each other, with Halo in between.
Aphrodite is the second orbital body of Murphy.
Shadow is the third orbital body of Murphy with a distance of .060Au and duration of 196 days.

One year later in 2512 Murphy will be about 0.8Au or 1.6 degrees behind Lux in their mutual progression CW around White Sun.
By 2517 this will be about 4.8Au and 10 degrees of lag behind Lux.
The next time Lux and Murphy will be this close will be about 2743.

So the closest planets outside Halo are Shadow, Aphrodite, and Persephone. The closest Core planets (inside Halo) these 3 will get to are Pelorum and Persephone.
The distance in 2511 ranges from 21.033Au to 22.067Au. Six years later in 2517 the distance will have increased by about a half Au.

You have referenced the White Paper as the source of tactical or strategic advantage of this distance. I am not sure I can confirm that this is a particular advantage - at least, strictly pertaining to distance.

Persephone is about 30Au from the White Sun and about 22Au from the closest planets around Murphy in 2511. This helps make clear why many in the Core seem cozier when staying in the Core, and those outside Halo may seem remote. For Hera, Lux is practically halfway to White Sun.

Perhaps the relevance of importance for Persephone and Hera are the concept of hopping over the Halo.
I am thinking of Portage, Wisconsin and the vast importance of it's trade and commerce for the entirety of the Western United States during the years between Lewis & Clark and the building of the railroad crossing the Mississippi River.
And also consider the Island Hopping Campaign of the Marines and Navy during WWII - hard for people today to understand when current planes travel nonstop across the Pacific.
Speaking of the Mississippi, Navigators and Masters of Shipping are certified only for certain well-defined sections of the River, and are not allowed to Pilot beyond the section they are rated for - the River is far too changing and treacherous.

Some ships in the Verse have limited range - recall Serenity has extenders which may increase her range. Maybe crossing Halo is a specialty of shipping. War gear is onerous, massive, and often needs to be pre-positioned to be effective.

I cannot say if this is reasonable, but you are free to discuss any ideas.

Does the above answer help, or satisfy the question?
Hopefully it adds to the understanding.

I think that assertion was solely from the White Paper.
I don't recall Joss saying anything about strategic reasoning about the War For Dominance.

Persephone was the largest body orbiting Lux.
Shadow was slightly larger, more massive, more gravity than Hera, with Aphrodite smaller than them.

Hera was the Capitol of Georgia System, according to White Paper.
