Laythe

Long known as Kerbin's sister moon, Laythe was seeded with life hundreds of millions of years ago when a large asteroid struck Kerbin - catapulting boulders with various life forms into orbit around Jool. Given its proximity to Kerbin, some of this impact debris found its way to Laythe, depositing a precious cargo of microbes and, according to some theories, whole plant seeds. This life quickly spread across the moon, until it became the lush green world we know today. (There are, however, fringe theorists who believe that life started on Laythe and was brought to Kerbin, but that's just absurd)

"Laythe is just as important in the grand scheme of things as Kerbin! Let's remake it completely, it deserves better." -NovaSilisko

Laythe keeps many of its stock properties in the revamped system. The same parent body, orbit, size, and atmospheric pressure. It is very much like Kerbin in that it is a large, habitable moon of Jool. Unlike (it's implied) on Kerbin, Laythe has no animal life. Alternis Laythe has more land than its stock counterpart, though it appears to be somewhat more volcanic.
