I suppose I see what you're saying. However, when we think of space in the Elder Scrolls we're actually.... not thinking of space. See, each of the planets is actually rather like the physical manifestation of an Aedra/ their realm. Masser and Secunda are literally the embodiment of the two halves of Lorkhan without the heart and the Earthbones in Nirn. "Outer space" in The Elder Scrolls lore isn't space as in that basic function that works in three dimensions, but rather Oblivion itself, which our eyes interpret as black. So in order to pass from Nirn and reach a planet, we wouldn't be using a spaceship so much as dimension-leaping through Oblivion, which may well be infinite and have infinite small planes as well as the Princes' "spheres of influence" within. And the sun is, ultimately, a gigantic hole in existence left by the Architect of Mundus, after whom it is named. The stars are similar holes.

tl;dr Normal physics may or may not apply when actually what may seem to be the same as in our world is, in fact, radically different.
