There are places in this universe that are very different from the planet you and I inhabit. Take, for example, the planet Dayko in NGC 5194 (the Whirlpool Galaxy). Dayko is in a stable orbit around a yellow dwarf in a binary system with a red dwarf (i.e., the planet is non-circumbinary). When it passes between the two stars, there are no nights. The light from the dwarf star makes the night sky orange or yellow. It is also the hottest time of the year, regardless of hemisphere—hot enough that plants drop their leaves and animals aestivate until it is over and the temperatures return to bearable levels. This biological imperative for annual aestivation has made space travel difficult for Daykonians.
