Eyu

== Overview ==
Eyu is a minineptune and the innermost planet of its star and the smallest planet in its system overall. It is an unusually small gas giant, measuring 4,506 kilometers across (~92.35% of Mercury's diameter), and is just 2.33x as massive as the Moon.
=== Atmosphere and characteristics ===
As mentioned before, Eyu is very small for a gas giant, even being the smallest planet in its entire system. It is tidally locked to its red dwarf star, and takes 2.83 days to orbit it. Because of its small size, the planet has a rather high ESI for gas giants: 0.699. Its atmosphere is 4341 times thicker than Earth, and is composed entirely out of water vapor.
=== Moons ===
Eyu has only one unnamed moon that has a mean diameter of 42.18 kilometers and takes 16 hours and 42 minutes to orbit its planet. The moon has a density of 4.54 g/cm3 and is tidally locked.
