The Equator during the boreal winter, spanning from December to March. The equator is a circle of latitude that divides a spheroid, such as Earth, into the Northern and Southern hemispheres. On Earth, the Equator is an imaginary line located at 0 degrees latitude, about 40,075 km (24,901 mi) in circumference, halfway between the North and South ...
Northern Hemisphere: The half that lies north of the Equator. This hemisphere contains approximately 68% of Earth's landmass and is home to about 90% of the global population. [4] It includes North America, Europe, Asia, and most of Africa. Southern Hemisphere: The half that lies south of the Equator. It contains approximately 32% of Earth's ...
The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. By extension, it is also a plane of reference in the equatorial coordinate system. In other words, the celestial equator is an abstract projection of the terrestrial equator into outer space. [ 1]
The Southern Hemisphere is highlighted in yellow. The hemispheres appear to be unequal in this image because Antarctica is not shown. The Southern Hemisphere is the half ( hemisphere) of Earth that is south of the Equator. It contains all or parts of five continents [ 1] (the whole of Antarctica, the whole of Australia, about 90% of South ...
The Equator, but including those islands of the Gilbert and Galàpagos [sic] Groups which lie to the Northward thereof. On the East. The meridian of Cape Horn (67°16'W) from Tierra del Fuego to the Antarctic continent ; a line from Cape Virgins ( 52°21′S 68°21′W / 52.350°S 68.350°W / -52.350; -68.350 ) to Cape Espiritu ...
The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun. [ 1][ 2][ a] From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. [ 3] The ecliptic is an important reference plane and is the basis ...
Eastern Hemisphere. The Eastern Hemisphere is the half of the planet Earth which is east of the prime meridian (which crosses Greenwich, London, United Kingdom) and west of the antimeridian (which crosses the Pacific Ocean and relatively little land from pole to pole). It is also used to refer to Afro-Eurasia ( Africa and Eurasia) and Australia ...
The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean . At this latitude the sun is visible for 16 hours, 22 minutes during the summer solstice and 8 hours, 4 minutes during the winter solstice. [ 1]
