| Jan 2, 2019 at 10:12 | comment | added | MolbOrg | downvoted for changing the tag to HS after there bunch answers present which are not HS at all. You probably should have been created another Q then | |

| Jan 1, 2019 at 15:10 | comment | added | Tristan Klassen | But even an inclined binary system will still allow all three bodies to be collinear sometimes. I'm asking if there's a system that NEVER allows that. (And can an inclined binary system like that be stable with suitable inclination and spacing ratio to make it significant anyway?) | |
| Jan 1, 2019 at 11:35 | comment | added | G0BLiN | Regarding "If it orbits one star of a binary, there will be a point in its orbit where the other star passes behind the one the planet orbits." and "If it orbits both stars, there will likewise be a point where all three are in a line" - these are true only if both stars share the same plane as the orbit of the planet (consider e.g. a state where the secondary star is "above" the orbital plane of the planet and the primary star...) | |

| Dec 30, 2018 at 22:03 | comment | added | chasly - supports Monica | Your title asks a different question from the text. One asks for a day that's longer than night. The other asks that the planet always be more than half illuminated. That is not the same question at all. | |

| Dec 30, 2018 at 21:14 | comment | added | Tristan Klassen | Demigan: Yeah, definition is vague. But, for example, moonlight on Earth isn't bright enough to be thought of as 'day'. At what intensity does light become considered 'day' on Earth -- a few % of its full intensity? Karl: Yeah, I know those. But like eclipses, they're minor effects. | |

| Dec 30, 2018 at 20:57 | comment | added | Demigan | Wont that depend on your definition of "day"? I think Alpha Centauri has 3 stars but one is so far outwards it doesnt illuminate much anymore. A similar system with the third star closer to the center (perhaps a "small" red dwarf?) would illuminate enough to give that "day" cycle. | |
