Mine is based on the Lunar Lorkhan Theory, saying that Masser and Secunda are two halves of Lorkhan's physical incarnation, but delves into another subject completely, The Serpent Constellation and its behaviors.
Now, I am going to go out on a limb here and say that when a planet splits in two, as Lorkhan's "flesh-divinity" did, it isn't a very smooth kind of split, bits of... space stuff can just go flying anywhere. Four large bits of this space stuff clung together in their own small gravitational system; a system large enough to create its own orbit around Nirn itself.
This system, let's call it "The Lorkhan Four", is made of fairly large bits of space stuff, but, they are just the right size to be seen as stars through a telescope, maybe a constellation on it's own,http://images.uesp.net//0/00/OBbsign_Serpent.jpg
This next part is a bit of a stretch, but bare with me. The Lorkhan Four, given that is fundamentally made up of Aedra, has properties unseen in the other constellations, such as an odd orbit pattern that seems to be in some relationship with the Warrior (http://www.imperial-library.info/content/redguard-firmament). Now, here's where it gets interesting. The governing planet of the Warrior is Planet Akatosh.
The Jist of Barael's Serpent Theory
The Serpent "Constellation" isn't made of stars atall, it is actually remains of Planet Lorkhan, that are closer then previously thought, orbiting Nirn, and evading the Planet Akatosh.
If any of this makes sense to you, please tell me. It pretty much came to me in a dream, then was followed by some research.
