Eastern Hemisphere no relation Equator
Geography
The almost perfect circle (the earth is an oblate spheroid that is fatter around the equator), drawn with a line, demarcating the Eastern and Western Hemispheres must be an arbitrarily decided and published convention, unlike the Equator (an imaginary line encircling Earth, equidistant from its poles), which divides the Northern and Southern Hemispheres. The prime meridian at 0° longitude and the antimeridian, at 180° longitude, are the conventionally accepted boundaries, since they divide eastern longitudes from western longitudes. This convention was established in 1884 at the International Meridian Conference held in Washington, D.C. where the standard time concepts of Canadian railroad engineer Sir Sandford Fleming were adopted. The Hemispheres agreed do not correspond with exact continents. Portions of Western Europe, West Africa, Oceania, and extreme northeastern Russia are in the Western Hemisphere, divorcing it from the continents which form the touchstone for most geopolitical constructs of "the East" and "the West".
Consequently, the meridians of 20°W and the diametrically opposed 160°E are often used outside of matters of physics and navigation, which includes all of the European and African mainlands, but also includes a small portion of northeast Greenland (typically reckoned as part of North America) and excludes more of eastern Russia and Oceania (e.g., New Zealand). Prior to the global adoption of standard time, numerous prime meridians were decreed by various countries where time was defined by local noon (thereby, local ).
The center of the Eastern Hemisphere is located in the Indian Ocean at the intersection of the equator and the 90th meridian east, 910 km west of Indonesia in the Ninety East Ridge. The nearest land is Simeulue Island at 2°35′N 96°05′E.
The land mass of the Eastern Hemisphere is larger than that of the Western Hemisphere and has a wide variety of habitats.
