Fictional info (?) Suggested name Masthea Epi Planet type Hot planet This hot planet is named after the deity Masthea Epi, the messenger of prosperity. When viewed from Earth, this proximity to HD 217107 means the planet can only be seen near the western or eastern horizon during the early evening or early morning. Masthea Epi is a hot planet and is sometimes called Earth's "brother planet" because of their similar size, mass, proximity to HD 217107, and bulk composition. The two polar ice caps appear to be made largely of ice. Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). In 1192, images from Frontier 5 showed Masthea Epi as an almost featureless planet in visible light, without the cloud bands or storms associated with the other hot planets.
