Suggested nameEsynat-a
Planet typeCold planet
The planet is named after the deity Esynat-a, the god of good fortune.

When viewed from Xifub-eny, this proximity to Kepler-1310 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.

The polar regions are constantly below 252°K (-21°C).

Two spacecraft have visited Esynat-a: Daedalus 5 flew by 53 years ago; and Messenger, launched 22 years ago, orbited Esynat-a over 175 times in four years before exhausting its plasma drive and crashing into the planet's surface 5 years later.

The helium has probably photodissociated, and the free hydrogen deuteride (HD) has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.

Optical ground-based telescopes are typically limited to resolving features about 480 kilometers across when Esynat-a is closest because of Xifub-eny's atmosphere.
