You poor thing, unable to match one daily rotation with its maximum equatorial speed of 1037.5 miles per hour with the temperatures fluctuations throughout the day when the Sun is in view and when the other stars are in view.

At the South and North poles the Sun is in view for 6 months at a time due to a separate rotations hence two distinct rotations serving two distinct day/night cycles.

The next step is apply comparative inclinations to determine why habitable zones across latitudes are influenced by the daily and annual rotations, the relationship to the circle of illumination and to the central Sun.
