Hilton argues Kolob is at the center of the Milky Way Galaxy.
Lynn M. Hilton, The Kolob Theorem: A Mormon’s View of God’s Starry Universe (n.p., 2005), 86
Abraham saw, by the Urim and Thummim, the huge star Kolob, “that it was nearest to the throne of God” (Abraham 3:2); that Kolob is the first of all of God’s creations and is the greatest (largest in mass) of all the stars (Abraham 3:16), and that it “governs all the stars which belong to the same order as that upon which thou [Abraham] standest [earth]” (Abraham 3:3). The scriptures also establish that God’s throne is in the “midst [center] of all things” (Doctrine and Covenants 88:13). The Kolob Theorem proposes this is in the center of the Milky Way Galaxy.
