In today's world, Western Hemisphere occupies a prominent place in society. Whether due to its impact on popular culture, its relevance in academia or its influence on history, Western Hemisphere is a topic that does not go unnoticed. Over time, Western Hemisphere has generated great debates, been the subject of extensive research, and has captured the attention of millions of people around the world. In this article, we will explore the various aspects of Western Hemisphere, analyzing its importance, its evolution over the years, and its relevance today. From its origins to its impact on modern society, Western Hemisphere continues to be a topic of constant interest and discussion.
Half of Earth which lies west of the Prime Meridian and east of the 180th meridian
The Western Hemisphere consists of the Americas, excluding some of the Aleutian Islands to the southwest of the Alaskan mainland; the westernmost portion of Europe, both mainland and islands; the westernmost portion of Africa, both mainland and islands; the extreme eastern tip of the Russian mainland and islands (North Asia); numerous territories in Oceania; and a large portion of Antarctica.
In an attempt to match the Western Hemisphere more closely with the Americas, some sources use the 20th meridian west and the diametrically opposed 160th meridian east to define the hemisphere. This definition excludes all of the European and African mainlands, but still includes some islands associated with these continents, more of eastern Russia and Oceania, and part of Antarctica. It includes all islands of Alaska, but excludes a small portion of northeast Greenland. There is no hemisphere that includes all of the Americas while excluding all land outside of it, regardless of the meridians or points chosen to define it.
Sovereign states in both hemispheres
Below is a list of the sovereign states in both the Western and Eastern hemispheres on the IERS Reference Meridian, in order from north to south:
Below is a list of additional sovereign states which are in both the Western and Eastern hemispheres along the 180th meridian, in order from north to south. (France is not listed below due to its inclusion above, though the meridian does pass Wallis and Futuna.) With the exception of the United States (due to Wake Island, Guam and the Northern Mariana Islands), all of them are located on just one side of the International Date Line, which curves around them.
Russia, passing through Chukotka Autonomous Okrug. Its portion lying east of the 180th meridian is the only part of the country lying in the Western Hemisphere.
Kiribati, passing close to Arorae. The country has both the Equator and the 180th meridian (antimeridian) crossing through its territory. It is the only country located in four hemispheres.
