When the Earth orbits the Sun we see our star projected in the direction of 13 different constellations. These are named the zodiacal constellations.  
The time the Sun is projected in the direction of each constellation is not equal in number of days. For instance, it stays 8,4 days projected in the direction of the constellation Scorpius and 44,5 days in the direction of Virgo.
We can build a template that helps to understand how the visible planets to the naked eye move in relation to the stellar background and thus provide its location and visibility in relation to the local horizon.</langstring><langstring xml:lang=""/></description><keyword><langstring xml:lang="en">Astronomy</langstring><langstring xml:lang="en"> Solar System</langstring><langstring xml:lang="en"> planets</langstring><langstring xml:lang="en"> astronomy</langstring><langstring xml:lang="en"> translation movement</langstring><langstring xml:lang="en"> scales</langstring><langstring xml:lang="en"> spatial orientation</langstring><langstring xml:lang="en"> constellation</langstring><langstring xml:lang="en"> Zodiac</langstring></keyword></general><lifecycle><status><source>LOM v1.0</source><value>final</value></status><version><langstring xml:lang="en">1.0</langstring></version><contribute><role><source>LOM v1.0</source><value>author</value></role><date><datetime>2009-01-01</datetime><description/></date><centity><vcard>Leonor Cabral</vcard></centity><centity><vcard>Paula Furtado</vcard></centity></contribute><contribute><role><source>LOM v1.0</source><value>publisher</value></role><date><datetime>2013-04-04</datetime><description/></date><centity><vcard>Leonor Cabral</vcard></centity></contribute></lifecycle><metametadata><language>en</language><metadatascheme>LOM v1.0</metadatascheme><contribute><role><source>LOM v1.0</source><value>creator</value></role><date><datetime>2013-06-10</datetime><description/></date><centity><vcard>Leonor.Cabral</vcard></centity></contribute><contribute><role><source>LOM v1.0</source><value>validator</value></role><date><datetime>2013-06-10</datetime><description/></date><centity><vcard>Ana Costa</vcard></centity></contribute></metametadata><technical><duration><datetime/><description/></duration><requirement><type><source>LOM v1.0</source><value>browser</value></type><name><source>LOM v1.0</source><value>any</value></name><minimumversion/><maximumversion/></requirement><requirement><type><source>LOM v1.0</source><value>os</value></type><name><source>LOM v1.0</source><value>any</value></name><minimumversion/><maximumversion/></requirement><installationremarks/><otherplatformrequirements/><size></size><format>text/html</format><location>http://portal.discoverthecosmos.eu/node/195733</location></technical><rights><cost><source>LOM v1.0</source><value>no</value></cost><copyrightandotherrestrictions><source>LOM v1.0</source><value>no</value></copyrightandotherrestrictions><description/></rights><educational><interactivitytype><source>LOM v1.0</source><value>mixed</value></interactivitytype><interactivitylevel><source>LOM v1.0</source><value>high</value></interactivitylevel><semanticdensity><source/><value/></semanticdensity><difficulty><source>LOM v1.0</source><value>medium</value></difficulty><learningresourcetype><source>LOM v1.0</source><value>Guided Research</value></learningresourcetype><context><source>LOM v1.0</source><value>2 didactic hours</value></context><typicalagerange><langstring xml:lang="en">9-12</langstring><langstring xml:lang="en">12-15</langstring></typicalagerange></educational><classification><purpose><source>LOM v1.0</source><value>Discipline</value></purpose><taxonpath><source><langstring xml:lang="en">Science</langstring></source><taxon><id/><entry><langstring xml:lang="en">Astronomy: Constellations</langstring><langstring xml:lang="en">Astronomy: Earth</langstring><langstring xml:lang="en">Astronomy: Orbit</langstring><langstring xml:lang="en">Astronomy: Planets</langstring><langstring xml:lang="en">Astronomy: Solar system</langstring><langstring xml:lang="en">Astronomy: Solar system - other</langstring><langstring xml:lang="en">Astronomy: Sun</langstring><langstring xml:lang="en">Astronomy: Zodiac</langstring><langstring xml:lang="en">Scientific enquiry: Creativity in science</langstring><langstring xml:lang="en">Useful materials and products: Everyday materials</langstring></entry></taxon></taxonpath><description/></classification></lom>
