Fictional info (?) Suggested name Porthel Planet type Small gas planet Porthel is the smallest and most crater filled planet in its solar system. Porthel is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Porthel is orbiting K2-266 every 19 Earth days. It is named after the deity Porthel, the demon of dreams. Like Heandala-enthi, Porthel has been orbiting K2-266 for 8.4 billion years, and never moves more than 18 degrees away from K2-266. The smooth Borealis basin in the northern hemisphere covers 25 percent of the planet and may be a giant impact feature. Liquid water cannot exist on the surface of Porthel due to low atmospheric pressure, which is less than 7 percent of Earth's, except at the highest elevations for limited periods. Porthel has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Galileo orbiter. Its north and south poles, therefore, lie where most other planets have their equators.
