PC calls Kolob a planet near the Pleiades star system.
Peter Canavan, "The Earth, As We Find It," The True Latter Day Saints' Herald 20, no. 5 (March 1, 1873): 135–136
In the fragment called the Book of Abraham, as translated by Joseph Smith, the martyr, from the papyrus found on a mummy, we are told, (I quote from memory), that the Lord taught Abraham the science of astronomy. We are also informed that there is a central or governing planet called "Kolob."
This agrees with recent discoveries in astronomy. One, Maedler [Johann Heinrich von Mädler], discovered that our solar system is moving around a point in the direction of "Pleiades," or the "Seven Stars," requiring an immense time to perform a single revolution.
This may be where the planet "Kolob" is situated; and it may be the location of the "heaven of heavens." And there may be a significant meaning in the question propounded to Job by the Lord; Job 38: 31: "Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion?"
