Celestial Bodies are very similar to Human bodies, they are made of decomposable matter. In the Bible 1st Kings 2:2 we see the way of all the Earth is death. The Earth will die, the stars and galaxies are exhaustable. It is a matter of time that everything around us will expend the energy of life. That energy is to be renewed into incorruptible matter as we see in the resurrection.
Joseph Smith used the word place to differentiate the levels of Glory yet not indicate the location of these Kingdoms. Our 10th article of Faith is a better understanding of this. 'We believe in the literal

bTen Tribes; that
cZion (the New Jerusalem) will be built upon the American continent; that Christ will
dreign personally upon the earth; and, that the earth will be
erenewed and receive its
fparadisiacal gglory"
