Average distance = average of perihelion and aphelion which are 8.449AU and 18.891AU, so wit would be 13.67AU

Surface temperature is thought to be around 75 Kelvin (wiki), but the various articles around seem to state it's a rather volatile environment, with some folks having measurements around 130K, for example.
