Orson F. Whitney identifies Kolob as a planet near the "Celestial Throne."

According to Kolob. — The Prophet's translation of the Book of Abraham explains that these greater days are "after the time" or according to the reckoning of Kolob, a mighty governing planet nearest the Celestial Throne, a planet revolving once in a thousand years. This period, then, is a day upon Kolob. One might well suppose such a day to have figured in the warning given to Adam: "In the day that thou eatest thereof thou shalt surely die"; for Adam, after eating of the forbidden fruit, lived on to the age of nine hundred and thirty years. St. Peter may have had the same thing in mind when he wrote: "One day is with the Lord as a thousand years, and a thousand years as one day".
