Geocentric
Back to people overviewA model of the universe which placed the Earth at its centre. In the second century CE, Claudius Ptolemy advocated for a geocentric model and the system predominated well into the 16th century. Nicolaus Copernicus’s famous proposal of a heliocentric model of the universe – with the sun at the centre of the solar system – was considered by many at the time to be heretical or simply wrong. Astronomers such as Tycho Brahe continued to use the geocentric system.
