ok i have always wandered what those other 2 planets are, because im pretty sure only mundus/nirn what ever you call it was the only world created. could the big red planet be oblivion and the little whit one be like the heavens of the mundas/nirn (i forgot which one it is) world? or possibly where the dwemer diaspeared to?

Ya referring to http://www.uesp.net/wiki/Lore:Masser and http://www.uesp.net/wiki/Lore:Secunda?

Moons, not planets.

lol i get it now, the only section of lore i read was the timeline for the ages, i think im going to have to go back and read the whole lore section so i can stay informed.

The plane(t)s of the Aedra mainfest themselves as spheres (not sure how loreified this is) but nirn is the only actual planet.

Or so one would believe. I'm not that familiar with lore as of now, but I'd assume there's as much superstition and limited knowledge on Tamriel as there were (and still are) irl.

Edit: Or differences in perspective and in the creation of the objective world.

There might be other planets......in Mundus and Oblivion alike.

Don't forget Yessir.

Spoiler:

No.

edit: Clarification: not other planets in the Aedra sense. There are NO planets in Oblivion whatsoever.

There are other planes in Oblivion, not planets. Oblivion surrounds Nirn.

What's to say that the planes aren't actually planets floating out in the Void of Oblivion though?

Perhaps they're like Plane(t)s?

Abstract thought.
