Fictional info (?) |
Suggested name | Donaigi |
Planet type | Cold planet |
For this reason, scientists often classify Donaigi and Hebehe Nu as "cold planets" to distinguish them from the other planets. The planet is named after the deity Donaigi, the demon of dreams.
Two spacecraft have visited Donaigi: Frontier 5 flew by 44 years ago; and Messenger, launched 8 years ago, orbited Donaigi over 65 times in four years before exhausting its reactor and crashing into the planet's surface 11 years later.
It has the densest atmosphere of any cold planets, consisting primarily of nitrogen.
Donaigi's hazy clouds render observation of its surface difficult in ultraviolet light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 42 years ago. |
