The answer to the question you were asked is no. The Celestial is the name of the planet on which God resides, and Kolob is the governing star that is closest to it. Kolob governs other stars which have been placed below it in a sequence until you come to our solar system, of which our Sun is our governing star. When the Millennium is completed, this earth, having fulfilled its mission, will inherit a celestial glory and become the Celestial Kingdom. Those who have lived in mortality on this earth, accepted covenants either in this life or the Spirit World, and stayed true to their covenants after making them, will together reside on this earth in its celestial state for eternity with celestial bodies. You can read about this in the Doctrine and Covenants 88:25-29 Feel free to let me know if you have any other questions.
