Edmos is a standard hydrogen-helium gas giant with traces of methane in its atmosphere. If Trebin's terraforming is successful, it is expected that a helium-3 fuel refining facility for the system will be set up here.

Edmos is too small to be a "standard hydrogen-helium gas giant" (William Hubbard, The New Solar System 4th ed, 1999; p. 194). It is more likely a dense "ice giant" like Neptune or Gliese 436 b.
