How Can Planetary Movements Affect Time and Illumination on an Inhabited Planet?

[QUOTE="snorkack, post: 6855560, member: 436348"] That is, you don´t catch the implied question answered? "Would it be day all the time"? If the question is "How to illuminate whole planet at one time", the requirement will be that two stars must be pretty closely antipodal. Which will be a brief time, even if prone to recurring. And which simultaneously causes every place of the planet to be illuminated through rotation. If the question is "How to illuminate one region of planet for an extended time compared to Earth rotation" then the first answer applies. But then it will not be the only answer. There will be two more answers: 2. The planet is tidally locked to one source of illumination. Then the near side will be permanently illuminated 3. One of the stars is illuminating a polar region. The pole turned towards the more distant, therefore slow moving star will be illuminated for a long time compared to polar days caused by nearby star. [/QUOTE]
