The inner planets (Mercury, Venus, Earth, Mars) have rocky surfaces composed of silicate minerals and metals. The outer planets (Jupiter, Saturn, Uranus, Neptune) have gas surfaces, primarily composed of hydrogen and helium. Additionally, outer planets may have icy surfaces due to the presence of water and other ices.
Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
The outer tissue layer of an organism is typically made up of epithelial cells. These cells are responsible for protecting the organism from the external environment and regulating the exchange of materials between the organism and its surroundings.
Inner planets, such as Earth, Mars, Venus, and Mercury, are smaller, denser, and composed mainly of rocky materials. They have solid surfaces and relatively high temperatures. In contrast, outer planets, like Jupiter, Saturn, Uranus, and Neptune, are much larger, primarily made of gases and ice, and have lower densities. They also have no solid surfaces and are much colder than inner planets.
They have rocky surfaces.

They cover the surfaces and the cavities of the body. Outer most layer of surfaces is an epithelial cell

Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
Squamous epithelial cells are flat, thin cells that line surfaces such as the skin and form the outer layer of the skin, lining of blood vessels, and inner lining of the mouth and esophagus. They play a role in protection, secretion, and absorption in the body.
Excretion is the means by which waste material is removed from cells through the porous outer membrane.
Mostly on the inner and outer surfaces of the heart (pericardium & endocardium).

No. While prokaryotic Cells have their Cell Coats make from various mostly Cellulosic materials, eukaryotic Cells produce a [sugar-protein] glyco-callyx coat.
They have rocky surfaces.
No, gram positive cells do not possess an outer membrane.
