This question just brings up a curiosity on why did Galileo call sunrises and sunsets terminators. I feel as though that would be a more important question than what did he call terminators. -Nathankr42

Also, one other way to remember this question is referring it to Arnold Schwarzenegger 's movie, The Terminatior. Arenee994 (discuss • contribs) 17:14, 13 April 2016 (UTC) Arenee994
