Laythe is one of the four natural satellites of Jool. Although mostly covered in seas, Laythe has numerous rocky, sandy islands.

Atmosphere
Laythe's atmosphere begins at 55,500 meters and is slightly less dense than Kerbin's. It is the only natural satellite in the game which has an atmosphere.
Like all other atmospheres in the game, Laythe's atmosphere fades exponentially with increasing altitude (with a scale height of 4000 m). In general, the atmospheric pressure on Laythe at an altitude expressed in meters is:[1]
- p_l = 0.8\ e^{-altitude/4000}
With proper aerobraking near Laythe and Jool, reaching Laythe may require the least delta-V of all of Jool's moons. A periapsis of 119.5 km on a Jool approach will put your apoapsis roughly near Laythe's orbit.
