boring physics stuff... i mean important physical characteristics

So, after a hiatus of sorts (working on some map commissions and trying to get some work done on my gigantic stereographic world map) I'm back with what might possibly be my most boring post,a bout aphelions, eccentricities (not the interesting sort) and orbits.
      The following is a small excerpt from about 10,000 words-worth of details that will be included in the stereographic map (amazingly, most of the surface of the image is actually a map, despite all those words!) and I thought I'd include them here to show I'm still alive. Most of the information below was slowly cultivated over my many years of working on the world, updated, replaced, changed, tinkered with, until slowly it became something believable.

Regarding the Sphere of Elyden
Elyden. She is our home, hanging in the Æther, product of the divine shaping of the Two-and-Twenty beings known as the Demiurges – shaper-gods whose literal hands were (and are, in some cases) responsible for the creation and evolution of this terraqueous globe that is called home by us and so many other peoples and races.
            Elyden is the third of seven known Ætheric bodies, sometimes known as planets, to have been discovered by observers (astronomers, astrologers, orrerists, Penumbrists, et al) within the system known as Sorchar; the others being, in successive order moving outwards from our star Sor: Hael, Algol, Elyden, Liviad, Gnihlas, Cykranosh, and Nihav. Others have been postulated by mortal observers, though the evidence given by otherworlders and those with abilities beyond the ken of ‘mere mortals’, suggest that the Sorchar system is complete with one star and seven planets. Many of those stars are themselves orbited by one or more satellites, with Liviad and Gnihlas each known to possess seven and three, respectively. Elyden herself is orbited by two satellites – Arakhamé the Red and Siella the White (Details on the two satellites may be found elsewhere on this treatise).
            Elyden orbits Sor at a mean speed of ~65,000-miles per hour in a counteclockwise direction when observed from above the northern pole of Kholamor. She orbits Sor at a mean distance of 92,000,000 miles, with a periapsis of ~90,500,000-miles and an apoapsis of ~93,500,000-miles. She has an equatorial radius of ~6,028-miles, with an equatorial circumference of ~37,880-miles and a polar circumference of ~37,815-miles and an estimated total surface area of 455,957,666-miles.
            Elyden is a rocky planet, with a metallic core, rocky shell and earthen crust in the depressions of which collect oceans of water; giving the term terraqueous globe (Elyden is thought to be the only terraqueous globe in Sorchar, with the other planets thought to be either terraous or gaseous in nature). Above this is an atmosphere that retains gasses due to the sphere’s gravity. It is this atmosphere that largely protects us from Ætheric cauterity, severe effects of the elementae vitale originating without Elyden and also regulates temperature extremes between night and day.
            Of the seven Sorchari planets, Elyden is thought to be the only one with an atmosphere and liquid water, both believed to be vital components in the propagation of mortal life, though it has not been entirely discounted that other forms of life might exist on extraterraqueous globes or even in the Penumbra of the Firmament themselves (indeed, the number of creatures whose existence relies on one of the two elementae vitale, as they are called, would lend credence to the belief in extraterraqueous life, though little solid evidence exists to support it yet). Some claim the very existence of isawhani (Otherworlders) is direct proof of the ability of either the Firmament or the Penumbra of spawning and sustaining ‘life’, though given their detached and, for want of another term, alien personalities, first-hand evidence has been difficult to glean.
            Despite this mystery, Elyden has had no shortage of what naturalists classify as life (described as Vitalism – the fundamental difference between organic and inorganic matter, and the belief inherent that life can only be derived from organic matter), even in these dark days that bear witness to her death throes.
            If one disregards the corruption of the natural world and goes back, even as little as one millennia, one can find a plethora of examples of life in almost all conditions imaginable – the is little-to-no terrain or climate catalogued by our brave explorers that have been unequivocally bereft of life. In some form, minute as it may be, some manner of life exists. Be it microscopic organisms that subsist on the oxidisation of metal, or the gigantic behemoths that lurk in the abysms of our oceans, life has, since the appearance and hubris of the Demiurges, proliferated, and there is little reason to doubt that it will disappear any-time soon.
