Fictional info (?) Suggested name Pomely-cisco Planet type Cold planet It is the second-brightest natural object in the night sky after Thyssi Tia, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight. This planet is named after the deity Pomely-cisco, the bringer of the sky. When viewed from Earth, this proximity to HD 1502 means the planet can only be seen near the western or eastern horizon during the early evening or early morning. At this time it may appear as a bright star-like object, but is often far more difficult to observe than Thyssi Tia. As seen from HD 1502, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years. Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Pomely-cisco's distance from HD 1502 is only about two-thirds (or 33 pct) of its distance at aphelion. Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 105°K (-168°C) at night to 910°K (637°C) during the day across the equatorial regions. Pomely-cisco is a cold planet and is sometimes called Thyssi Tia's "sister planet" because of their similar size, mass, proximity to HD 1502, and bulk composition. It has the densest atmosphere of the three cold planets, consisting mostly of hydrogen chloride. 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).
