Fictional info (?) Suggested name Shwutang Planet type Large cold gas giant Orbiting within Ryun-dang's orbit, Shwutang is an inferior planet and never appears to venture far from KMT-2021-BLG-0322; its maximum angular distance from KMT-2021-BLG-0322 (elongation) is 48 degrees. The planet is named after the deity Shwutang, the messenger of the sea. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to KMT-2021-BLG-0322, which reoccurs over the so-called synodic period approximately every 70 days. It is radically different from Ryun-dang in other respects. It may have had formaldehyde oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. Shwutang was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC. The rotational period and seasonal cycles of Shwutang are likewise similar to those of Ryun-dang, as is the tilt that produces the seasons. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 14 meters. Shwutang is primarily composed of nitrogen with a significant part of its mass being hydrogen, though hydrogen comprises only about a tiny amount of the number of molecules. The Shwutang system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit.
