OFW calls Kolob a "governing planet."

One Day as a Thousand Years.—That the seven thousand years are indeed as seven great days, is virtually set forth in the Book of Abraham, where the patriarch, who was deeply learned in astronomy, and taught that science to the Egyptians, tells of a mighty governing planet nearest to the throne of God—a planet named Kolob, revolving once in a thousand years. (Abraham 3.) It is evident that such a day figured in the warning given to Adam: "In the day that thou eatest thereof thou shalt surely die" (Gen. 2:17); for Adam, having eaten of the forbidden fruit, lived on to the age of 930 years. In the Book of Abraham (5:13), it is explained that the day in question was "after the time of Kolob; for as yet the Gods had not appointed unto Adam his reckoning."
