PPP describes Kolob as a planet or sun.
Parley P. Pratt, Key to the Science of Theology (Liverpool: F. D. Richards, 1855), 157–158
The science of history will embrace the vast "univercoelum" of the past and present. It will in its vast compilations, embrace and include all nations, all ages, and all generations; all the planetary systems in all their varied progress and changes, in all their productions and attributes.
It will trace our race in all its successive emigrations, colonies, states, kingdoms and empires; from their first existence on the great, central, governing planet, or sun, called Kolob, until they are increased without number, and widely dispersed and transplanted from one planet to another, until, occupying the very confines of infinitude, the mind of immortal, eternal man, is absorbed, overwhelmed, wearied with the vastness, the boundless expanse of historic fact, and compelled to return and retire within itself for refreshment, rest and renewed vigour.
