Here are some of my peeves with space, the final frontier, in books and movies. At best these elements are not even mentioned, and at worst (read: usually) they're exactly wrong. Maybe it will help someone who's writing a SF to get it right for a change.
1. Rogue planets. I.e., planets that escaped the gravity well of a sun, and are just going solo like Leeroy Jenkins.
Thing is, SF seems to love depicting them as normal planets, even with plants and strange animal life and all, only dark. You know, for lack of a sun. As seen for example in DS9.
Now even skipping the issue of plant life without a sun, quick what's the temperature in places that don't get much sun influx? Like, say, the Antarctic? Yeah. But even that gest some heat through the atmosphere from the places that do get some sun. So a more apt comparison is, quick, what's the surface temperature of Pluto? Yeah, it's 44 Kelvin (-229 Celsius or -380 Fahrenheit). This will eventually end up even colder.
Not only it won't support any kind of life, but here's a thought: it's 10K below the FREEZING point of oxygen (54.36K) and nitrogen (63.2K). Now that will go down a bit as the atmospheric presure drops as most of it freezes, but it won't be the kind of place where you can breathe without a helmet.
