The circuits of dark gravity bodies that surround Havona exhibit an equal density. 
Observation of the Milky Way reveals a higher density of stars when Orvonton is viewed in a certain direction. If we look in the direction of maximum density, we are looking towards Paradise.  The Dark Islands of Space are bodies with an incredible density. 
Some of the reddish, faintly glimmering stars have acquired a density at the centre of their enormous masses which would be expressed by saying that 1 cm3 of such a star, if on Urantia, would weigh 166 kg. 
The mass of your sun is slightly greater than the estimate of your physicists, who have reckoned it as about 2×10^30 kg. It now exists about halfway between the most dense and the most diffuse stars, having about 1.5 times the density of water. 
Nonsolid suns can attain a density equal to iron — about the same as Urantia. Most of the suns, however, are not so dense. One of our nearer neighbours has a density equal to that of our atmosphere, and Veluntia, one of the largest in Orvonton, has a density only 0.001 that of Urantia’s atmosphere. 
The lava layers of the #3#’s crust, when cooled, form granite. The average density of Urantia is a little more than 5.5 times that of water; the density of granite is less than 3 times that of water. The earth’s core is 12 times as dense as water.
