Earth radius (denoted as RšØ or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) ( equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) ( polar radius, denoted b ).
Earth's circumference is the distance around Earth. Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). Measurement of Earth's circumference has been important to navigation since ancient times.
Solar particle event. Radio emission. v. t. e. Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetosphere. Earth has two such belts, and sometimes others may be temporarily created.
Dymaxion world map with continental landmasses (I,II,III,IV) and largest islands (1ā30) roughly to scale. This list includes all islands in the world larger than 2,500 km 2 (970 sq mi) and most of the islands over 1,000 km 2 (390 sq mi), sorted in descending order by area.
Pelso Plate ā Small tectonic unit in the Pannonian Basin in Europe. Timor Plate ā Microplate in Southeast Asia carrying the island of Timor and surrounding islands. Tisza Plate ā Tectonic microplate, in present-day Europe. Juan de Fuca Plate ā Small tectonic plate in the eastern North Pacific ā 250,000 km 2.
0.321ā³ to 0.133ā³. Hygiea ( minor-planet designation: 10 Hygiea) is a major asteroid located in the main asteroid belt. With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C ...
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 ...
Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 Ć 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
