RK and RWK describe Kolob as a "star" and "abode of the gods."
Ruth Kauffman and Reginald Wright Kauffman, The Latter Day Saints: A Study of the Mormons in the Light of Economic Conditions (London: Williams & Norgate, 1912), 141
The Father and Son live on a star called Kolob, which, though unknown to astronomy, was familiar to Joseph Smith, who described it as being situated in space "near the throne of God," and who, with a literal regard for the Scriptural statement that with the Lord a thousand years are as one day, said that it revolved upon its axis once in a thousand years. On this star Deity begets the spirits that are later to have an earthly birth. That is their destiny. If on earth they are good Mormons, living the faith and giving every opportunity as polygamy gives it for other spirits to come to their period of earthly probation, then they will return to starry kingdoms prepared for them. The sinners will descend into a lake of fire; but those who by good works of this sort have become eligible will return to the spheres that are "the future abode of the gods," there themselves to become gods.
