Fictional info (?)
Suggested nameDaherthea Sto
Planet typeHot gas giant
Daherthea Sto is the fourth planet from WASP-171 and the second-smallest planet in its solar system.

It is named after the deity Daherthea Sto, the goddess of good fortune.

Daherthea Sto's surface appears very cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

Daherthea Sto is a hot gas giant and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to WASP-171, and bulk composition.

Daherthea Sto is the site of Robusto Tower, the biggest volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
