Editing West (section)

==Navigation==
To go west using a compass for [[navigation]] (in a place where magnetic north is the same direction as true north) one needs to set a [[Bearing (navigation)|bearing]] or [[azimuth]] of 270°.

West is the direction opposite that of the [[Earth]]'s rotation on its axis, and is therefore the general direction towards which the [[Sun]] appears to constantly progress and eventually set. This is not true on the planet [[Venus]], which rotates in the opposite direction from the Earth ([[Retrograde and prograde motion|retrograde rotation]]). To an observer on the surface of Venus, the Sun would rise in [[Poles of astronomical bodies|the west]] and set in the east<ref name="compare">{{cite web |url=http://www.planetary.org/explore/topics/compare_the_planets/terrestrial.html |title=Space Topics: Compare the Planets |publisher=[[The Planetary Society]] |access-date=12 January 2016 |archive-url=https://web.archive.org/web/20060218084852/http://planetary.org/explore/topics/compare_the_planets/terrestrial.html |archive-date=18 February 2006}}</ref> although Venus's opaque clouds prevent observing the Sun from the planet's surface.<ref>{{cite book |title=Solar System Voyage |author=Serge Brunier |author-link=Serge Brunier |publisher=Cambridge University Press |year=2002 |page=40 |url=https://books.google.com/books?id=JkLxJOhEj-wC&pg=PA40 |isbn=978-0-521-80724-1 |translator-last=Dunlop |translator-first=Storm}}</ref>

In a map with north at the top, west is on the left.

Moving continuously west is following a [[circle of latitude]].
