Logo World Survey Data Gray.png

Meso Worlds are worlds that have a medium diameter.

  • The term specifically relates to solid (rocky) planets or worlds.
  • It describes a physical characteristic of the world.

Description / Specifications

A very broad term used to describe the general size of a world. A meso world is likely to have a moderate surface gravity, depending on its density and mass.

General size code categories:

Probable Orbits

Meso worlds may be located within any region of a system. Meso worlds are occasionally moons of larger rocky worlds or gas giants.
