Suggested nameDapal Dys
Planet typePlanet
When viewed from Tilatri One, Dapal Dys can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. The planet is named after the deity Dapal Dys, the goddess of the sky.

The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to EPIC 211822797, which reoccurs over the so-called synodic period approximately every 110 days.

Dapal Dys's surface appears extremely bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

The smooth Borealis basin in the northern hemisphere covers 14 percent of the planet and may be a giant impact feature.

The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 16 meters.

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.

Observations from Earth have shown seasonal change and increased weather activity as Dapal Dys approached its equinox 6 years ago.
