Slate is the fourth moon of Sarnus and is a rocky, atmosphere-less body with some unique features and implications. It is slightly smaller than Kerbin, with about just over 2/3 the surface gravity. Due to its mass, it is very easy to achieve an orbital encounter with Slate.

In-Game Description

Evidence suggests that Slate had an atmosphere only a few million years ago, until an unknown cataclysm stripped the atmosphere away, leaving only a dry husk behind. It's yellow and brown colors have inspired many painters since it's discovery, including the renowned Vincent Van Kerman.

Physical Characteristics

Slate is not significantly smaller nor lighter than Kerbin, although it appears that the moon has been stripped of its atmosphere somewhat recently. The lack of a magnetosphere seems to suggest that the core has cooled and the atmosphere has been blown away by solar wind, drying out the moon and cooling it even more. However, the presence of apparently active volcano Mount Nehelennia implies the planet is not entirely geologically dead after all.

From the average density, it is possible to estimate the internal structure. Slate may be composed of an iron-nickel core, with a radius of about 51 km; a solid, rocky, silicate mantle about 477 km thick; and the surface crust, around 10 km thick.

The surface of the moon shows impact craters consistent with atmosphere-less moons, but also dried lakebeds and valleys consistent with a dense atmosphere, making Slate an intriguing place to visit.

Biomes

Slate has a total of 16 biomes.
