Suggested nameHyrdelia
Planet typeCold planet
It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.

The planet is named after the deity Hyrdelia, the creator of dreams.

Hyrdelia's dense atmosphere make observation of its surface difficult in visible light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 42 years ago.

Two of Hyrdelia's moons, Kepan and Kecacali Nand, are are slightly unusually shaped.

Wind speeds can reach 144 metres per second.
