Overview[edit | edit source]
Argonia, also known as Onmar d I and CelWP G1 d I is the sole moon of Parchione, in the Onmar system. Argonia is known for its oceans of liquid argon, a rare sight considering the rarity of argon in the universe. Argonia was added in Release 2 and was the first CelWP body with surface liquid to be added.
Properties[edit | edit source]
Argonia is a relatively large moon, at nearly 3000 km in radius. It has a small mass compared to its size, giving a density of just 1.968 g/cm^3. This would make more sense for an icy, inherently low density moon such as Argonia than a rockier, hotter moon. As it is composed mainly of ice, Argonia does not have a magnetic field, but Parchione's magnetosphere keeps it from the radiation of Onmar.
Argonia's atmosphere is mostly comprised of nitrogen, methane and argon, giving it a bluish tinge and colouring its yellowish oceans of argon blue from space. Large pink ice fields cover Argonia's surface, littered with tholins.
Argonia's orbit is quite slow, due to the extremely low mass of Parchione at 1.77 earth masses. Argonia orbits Parchione every 13.061 days, at a semi major axis of 285,000 km. Argonia is tidally locked to Parchione, and so always shows the same face to it.
