Geography


The Western Hemisphere consists of the Americas, the western portions of Eurasia and Africa, the extreme eastern tip of Siberia (Russia), numerous territories in Oceania, and a portion of Antarctica, while excluding some of the Aleutian Islands to the southwest of the Alaskan mainland.


In an attempt to define the Western Hemisphere as the parts of the world which are not part of the Old World, there also exist projections which use the 20th meridian west and the diametrically opposed 160th meridian east to define the hemisphere.[1] This projection excludes the European and African mainlands and a small portion of northeast Greenland, but includes more of eastern Russia and Oceania.


The center of the Western Hemisphere is located in the Pacific Ocean at the intersection of the 90th meridian west and the Equator, among the Galápagos Islands. The nearest land is Genovesa Island at 0°19′00″N 89°57′00″W / 0.316667°N 89.95°W / 0.316667; -89.95.


The highest mountain in the Western Hemisphere is Aconcagua in the Andes of Argentina at 6,960.8 metres (22,837 ft).[4]



Sovereign states in both hemispheres




Below is a list of the sovereign states which are in both the Western and Eastern Hemispheres on the IERS Reference Meridian, in order from north to south:



  • Denmark (due to Greenland and the Faroe Islands; mainland Denmark lies entirely in the Eastern Hemisphere).


  • Norway (due to Jan Mayen; mainland Norway lies entirely in the Eastern Hemisphere).


  • United Kingdom


  • Netherlands (The islands of the Caribbean Netherlands lie entirely within the Western Hemisphere while the European Netherlands lies entirely in the Eastern Hemisphere.)


  • France


  • Spain


  • Algeria


  • Mali


  • Burkina Faso


  • Ghana


  • Togo

Below is a list of the sovereign states which are in both the Western and Eastern Hemispheres along the 180th meridian, in order from north to south. With the exception of the United States (Wake Island), all of them are located on just one side of the International Date Line, which is curved around them.



  • Russia (Siberia)


  • United States (United States Minor Outlying Islands)


  • Kiribati


  • Tuvalu


  • Fiji


  • New Zealand (Kermadec and Chatham Island groups are east of the 180th meridian)
