The flat top forms the inhabited world, which is surrounded by a circular oceanic mass. ... This is the geocentric model of the Solar System with the Earth at the ...
A geocentric coordinate system can be more convenient when dealing only with bodies mostly influenced by the gravity of the Earth (such as artificial satellites and the Moon), or when calculating what the sky will look like when viewed from Earth (as opposed to an imaginary observer looking down on the entire Solar System, where a different ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Diagram of the early Solar System's protoplanetary disk, out of which Earth and other Solar System bodies formed. The Solar System formed at least 4.568 billion years ago from the gravitational collapse of a region within a large molecular cloud. [b] This initial cloud was likely several light-years across and probably birthed several stars. [14]
The Flat Earth model is a belief that the Earth's shape is a plane or disk covered by a firmament containing heavenly bodies. Most pre-scientific cultures have had conceptions of a Flat Earth, including Greece until the classical period , the Bronze Age and Iron Age civilizations of the Near East until the Hellenistic period , India until the ...
In such systems the origin in the center of mass of the Earth, of the Earth–Moon system, of the Sun, of the Sun plus the major planets, or of the entire Solar System, can be selected. [166] Right ascension and declination are examples of geocentric coordinates, used in Earth-based observations, while the heliocentric latitude and longitude ...
In Charles Stross's Missile Gap, a copy of the whole Earth (along with copies of many other planets) is placed on an Alderson disk built around a black hole by unknown forces. Ian McDonald 's novel Empress of the Sun features a parallel-universe version of our solar system where creatures evolved from dinosaurs have converted all the mass to an ...
The cosmology of J. R. R. Tolkien's legendarium combines aspects of Christian theology and metaphysics with pre-modern cosmological concepts in the flat Earth paradigm, along with the modern spherical Earth view of the Solar System. The created world, Eä, includes the planet Arda, corresponding to the Earth.
