Subject: [FH] World Building
I got my birthday surprise gift from my wife (she was the one surprised--I told her "Sweetie, this is what you ordered for me"): _World building_ by Stephen Gillett. About $15 from Barnes and Nobles, this is the book to let you build a star system and make it interesting and authentic. I now know that Alarish orbits a brown dwarf (2.5% solar mass, or about 25 Jupiter mass) at 3 million kilometers, with a period of a bit more than a week. The brown dwarf orbits the primary, an M class star, at a distance of 0.8 AU and period of 1.16 years. Alarish gets insolation from the M star at the same total energy as Jupiter gets from Sol, although a lot more is from infrared. I haven't yet determined how much light it gets from the brown dwarf. I haven't gotten into the chemistry because Alarish is mostly rock and ice, not terraformable--but you could have some very interesting habitable planets if you wanted. Well worth the money, very highly recommended.
