Figure of the Earth - Wikipedia
WEBIn geodesy, the figure of the Earth is the size and shape used to model planet Earth. The kind of figure depends on application, including the precision needed for the model. A spherical Earth is a well-known historical approximation that is satisfactory for geography, astronomy and many other purposes.
3-D Earth Geometry - Interactive Mathematics
WEB3-D Earth Geometry. An interesting topic in 3-dimensional geometry is Earth geometry. The Earth is very close to a sphere (ball) shape, with an average radius of \displaystyle {6371}\ \text {km} 6371 km. (It's actually a bit flat at the poles, but only by a small amount).
Geographical centre of Earth - Wikipedia
WEBThe geographical centre of Earth is the geometric centre of all land surfaces on Earth. Geometrically defined it is the centroid of all land surfaces within the two dimensions of the Geoid surface which approximates the Earth's outer shape.
Earth ellipsoid - Wikipedia
WEBAn Earth ellipsoid or Earth spheroid is a mathematical figure approximating the Earth's form, used as a reference frame for computations in geodesy, astronomy, and the geosciences. Various different ellipsoids have been used as approximations.

Geodesy and the Size and Shape of the Planet Earth - ThoughtCo
WEBOct 14, 2019 · To ensure that the Earth's size and shape are studied accurately, geodesy, a branch of science responsible for measuring the Earth's size and shape with surveys and mathematical calculations is used. Throughout history, geodesy was a significant branch of science as early scientists and philosophers attempted to determine the Earth's shape.
Geodesy, Figure of the Earth - SpringerLink
WEBJan 1, 2021 · Geodesy is the discipline that deals with the measurement and representation of the Earth, its gravity field, and geodynamic phenomena (polar motion, Earth tides, and crustal motion) in three-dimensional time varying space.
Calculating the Size of Earth | Brilliant Math & Science Wiki
WEBTechnically Earth's shape is called the "geoid", an ellipsoidal shape. Possibly starting with Eratosthenes, over 2,200 years ago, mathematicians have attempted to calculate the size of a spherical or ellipsoidal Earth.
6(h). Earth-Sun Geometry - Physical Geography
WEBEarth-Sun Geometry. Earth Rotation and Revolution. The term Earth rotation refers to the spinning of our planet on its axis. Because of rotation, the Earth's surface moves at the equator at a speed of about 467 m per second or slightly over 1675 km per hour.
