(I) Parmil is designated the [[mainworld]]. It orbits the primary at a mean distance of 0.22 AU (32.9 million km), within the [[habitable zone]]. It has an orbital period of 47 days 20 hours: it is [[tidally locked]] to the primary. The axial tilt is 89 degrees. Parmil has a diameter of 4,632 km, a density of 4.23 g/cm³, and a surface gravity of 0.28 G. Tidal stresses generated by the gravitational pull of the primary cause frequent geological activity. Its atmosphere is rated as [[Trace atmosphere|Trace]], with a mean surface pressure of 0.003 bar and a composition of 85% carbon dioxide (CO<sub><small>2</small></sub>), 14% nitrogen (N<sub><small>2</small></sub>), and 1% argon (Ar), water vapor (H<sub><small>2</small></sub>O), abiotic oxygen (O<sub><small>2</small></sub>), neon (Ne) and other trace gases. Approximately 11% of the surface is covered in sheets of water-ice. Mean surface temperature: -75°C. | (I) Parmil is designated the [[mainworld]].
