Two miles. The 2 mile (10,560 feet or 3,218.688 metres) is a historic running distance. Like the mile run, it is still contested at some invitational meets due its historical chronology in the United States and United Kingdom. It has been largely superseded by the 3000 m (approximately 1.864 miles) and 5000 m, and by the 3200 m in NFHS American ...
Earth radius (denoted as R 🜨 or R E) 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 (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).

The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them. This arc is the shortest path between the two points on the surface of the sphere. (By comparison, the shortest path passing through the sphere's interior is the chord between ...
Vesta was the fourth asteroid to be discovered, hence the number 4 in its formal designation. The name Vesta, or national variants thereof, is in international use with two exceptions: Greece and China.

The satellites are pinpoint, while stars have created star trails due to Earth's rotation. A geostationary orbit, also referred to as a geosynchronous equatorial orbit[ a] ( GEO ), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the ...
