This mod adds planets based upon user suggestions, so as of now there are 4 planets.

PHOENIX: Phoenix is a tiny, tiny L-type main sequence carbon star with a soot-grey atmosphere and 4 planets orbiting it.

REKIESSE: With its great bulk, deadly features and great proximity to the star, this planet proves the most daunting of all the Phoenix worlds and it eludes all reasoning. The only supporting knowledge for its presence is that it formed at or beyond the outer border of the habitable zone and migrated in.

SEPTIS: A planet just a tad larger than Kerbin, but with a bit less gravity. It's close enough to Phoenix to feel quite a lot of tidal friction, but isn't close enough to be a molten wasteland. The surface is dotted with volcanoes, as well as patches of blue-black bacteria. No water is on the surface, but there are pockets underground that the bacteria feast on.

NEEBRILLE: Neebrille is a large planet almost entirely made of water, except for the iron core, and some small archipelagos floating ontop of the liquid water. Most of the water is frozen because of low temperatures or high pressures, but there is a wide equatorial 'river' that is liquid.

ABRAXA: Abraxa is a cold, dark world with a hot side covered in liquid ammonia. The planet is smack in the middle of the ammonia based habitable zone, so it's feasible for hosting alien life, and Abraxa will likely be the last refuge for kerbalkind once the Sun dies.
