çoullatrr

Çoullatrr is a fictional dwarf planet created for worldbuilding and science fiction settings. In the in-universe lore, it is a rocky-icy body orbiting a main-sequence star in the Veridia system and is noted for its cold, varied surface and relatively smooth interior. The term originates in a Veridian constructed language, where çoullatrr is used for astronomical objects and carries a sense of twilight and ice.

Discovery and naming

According to the fictional chronology, Çoullatrr was first observed by the survey vessel Lumen during an outer-system reconnaissance in the late 22nd century of the story’s timeline. The name follows Veridian phonotactics, with diacritic and double-consonant usage intended to reflect the culture’s historical naming practices for small bodies.

Orbit and physical characteristics

Çoullatrr has an estimated diameter of about 1,400 to 1,600 kilometers and orbits its star at roughly 2.7 astronomical units. Its orbit is modestly eccentric, yielding seasonal insolation variations over a multi-year cycle. The body is thought to be an icy-rock composite, producing a low albedo and a density consistent with a crust of water ice over a silicate interior.

Surface features and composition

Remote-sensing descriptions in the fiction depict vast ice-field plains dissected by polygonal cracking, with intermittent cryovolcanic domes. Temperatures are extremely low, and the atmosphere is negligible, effectively rendering Çoullatrr an airless world with a pristine, icy surface.

In fiction, Çoullatrr appears in Veridian chronicles and related role-playing materials, used to explore small-body geology and planetary nomenclature within that universe. Details vary by author, and the entry functions as a reference point in worldbuilding resources.
