Planets In Mirkheim

Poul Anderson's sf novel, Mirkheim, features or refers to the following planets:

Hermes (see also here, here and here)
Diomedes (see also here)
Vanessa (see also here)
Merseia (see also here and here)
Cynthia (see also here)
Gorzun (see also here and here)


Tidal action has forced one hemisphere of the small, eccentrically orbiting, librating planet Ikrananka to face its red dwarf sun but such slow rotation generates a weak magnetic field so that the planet retains an atmosphere although most of its water has frozen on the cold side making the warm side a slowly deteriorating desert whose inhabitants, struggling for survival in their season-less, rhythm-less environment, regard nature as hostile, believing in demons but not in gods, whereas dwellers on the edge of the Twilight Zone, with rain, snow, day, night and constellations, more conventionally believe in an annually dying and rising god and a single devil whose power can be neutralized. The latter are easier to trade with.


In the Cerulian system, resonance with the jovoid planet Ogre has multiplied perturbation and brought the eccentricity of the terrestroid Vixen's orbit close to one-half so that, with a 24 degree axial tilt and midsummer nearly at periastron, once every eighteen month year the northern hemisphere is scorched with four times the radiation that Terra receives from Sol - snow melts, rivers overflow, lakes bake dry, storms rage, fires break out, erosion prevents mountain formation, hot wind blows dust and ash across dry plains.
