Pot-Bellied Pig Housing. In the house, pot-bellied pigs need a space of their own with a bed, pillow or blankets. This space may be a large dog crate, a closet or a quiet room. If you have more than one pig, or other pets in the household, each should have his own bed.
Atmospheric composition. Uranus' atmosphere is predominantly made up of hydrogen and helium. Unlike Jupiter and Saturn, these light gases dominate only the outer edges of the planet, but are not a significant contributor to the rocky interior. The dull blue color of Uranus is caused by the presence of methane, which absorbs red light.
Internal structure. Uranusâs mass is roughly 14.5 times that of the Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptuneâs at roughly four times Earthâs.A resulting density of 1.27 g/cm3 makes Uranus the second least dense planet, after Saturn. This value indicates that it is made primarily of various ices, such as water, ammonia, and methane.The total mass of ice in Uranusâs interior is not precisely known, as different figures emerge depending on the model chosen; it must be between 9.3 and 13.5 Earth masses.Hydrogen and helium constitute only a small part of the total, with between 0.5 and 1.5 Earth masses.he remainder of the non-ice mass (0.5 to 3.7 Earth masses) is accounted for by rocky material. The standard model of Uranusâs structure is that it consists of three layers: a rocky (silicate/iron-nickel) core in the center, an icy mantle in the middle and an outer gaseous hydrogen/helium envelope.
