Editing Circumpolar star (section)

==Constellations==
A '''circumpolar constellation''' is a [[constellation]] (group of [[star]]s) that never sets below the [[horizon]], as viewed from a location on [[Earth]]. As viewed from the [[North Pole]], all fully visible constellations north of the [[celestial equator]] are circumpolar, and likewise for constellations south of the celestial equator as viewed from the [[South Pole]]. As viewed from the [[Equator]], there are no circumpolar constellations. As viewed from mid-northern latitudes (40–50° N), circumpolar constellations may include [[Ursa Major]], [[Ursa Minor]], [[Draco (constellation)|Draco]], [[Cepheus (constellation)|Cepheus]], [[Cassiopeia (constellation)|Cassiopeia]], and the less-known [[Camelopardalis (constellation)|Camelopardalis]], [[Lynx (constellation)|Lynx]] and [[Lacerta (constellation)|Lacerta]].<ref name=Young1897>{{citation| title=Uranography: A Brief Description of the Constellations Visible in the United States, with Star-maps, and Lists of Objects Observable with a Small Telescope| first1=Charles Augustus | last1=Young| publisher=Ginn | year=1897 | pages=9–14| url=https://books.google.com/books?id=tylLAAAAIAAJ&pg=PA9| postscript=. }}</ref>
