Tzgyrnél

Tzgyrnél is a fictional celestial body located in the Cygnus constellation. It is a gas giant planet, approximately twice the mass of Jupiter, orbiting a K-type main-sequence star named Lyra-7. The planet's atmosphere is predominantly composed of hydrogen and helium, with trace amounts of methane and ammonia, giving it a distinct greenish hue.

The planet possesses a prominent ring system, composed of ice particles and rocky debris, similar to Saturn's but denser. Tzgyrnél has at least ten known moons, the largest of which, Xylos, is believed to possess a subsurface ocean. Initial spectroscopic analysis suggests the presence of complex organic molecules in the upper atmosphere of Tzgyrnél, though the implications for potential life are purely speculative at this stage.

Tzgyrnél was first detected in the late 21st century by the Kepler-X space telescope during a survey of exoplanets. Its discovery was significant due to its unusual atmospheric composition and its location within the habitable zone of its star, although the planet itself is considered too hot to support liquid water on its surface. Further observations are planned to refine atmospheric models and search for additional moons.
