| Suggested name | Eukaso |
| Planet type | Hot gas giant |
| The planet is named after the deity Eukaso, the spirit of love and beauty.
When viewed from Earth, this proximity to WASP-121 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.
Plans have been proposed for rovers or more complex missions, but they are hindered by Eukaso's hazardous precipitation.
In November 1800, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Eukaso. |
