173. A planet with no atomosphere which has a very thick iron and nickel shell. A few kilometre thick area of lava, very thick layer of dirt and stone, huge glowing vegetation which grows almost all the way to where the core is which is just breathable air.

So a reverse planet sort of.

76. An asteroid belt given an atmosphere by megaflora that also holds all the asteroids together allowing travel between them.
