T'Kela And Pax

"Territory."

Clementian (also here) planetary creation begins:

"T'Kela rotated once in thirty hours and some minutes, with eight degrees of axial tilt. Considerable night remained when the car stopped..." (p. 66)

Right. The t'Kelan rotation period is longer than the Terrestrial rotation period so the nights are longer and this affects the experience of human visitors to the planet. Pretty obvious but the environmental data become considerably more complicated. 

The sun is red and apparently half again the size:

"...of Sol seen from Earth or Pax from Esperance..." (p. 67)

- the point being that, of the two human characters, van Rijn is from Earth whereas Joyce Davisson is from the colonized extra-solar planet, Esperance, which was colonized because it was Earth-like. Joyce remembers:

"...her home on the green planet of the star called Pax - a field billowing with grain, remote blue mountains, the flag of the sovereign world flying red and gold against a fleecy sky..." (p. 58)

We remember fleecy skies and cool green hills in Robert Heinlein's Future History. Sometimes the future histories seem very close.

We also find that we have previously summarized some complicated information about the t'Kelan environment.
