Copernican heliocentrism is the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. The Copernican model displaced the geocentric ...

Nicolaus Copernicus [b] (19 February 1473 – 24 May 1543) was a Renaissance polymath, active as a mathematician, astronomer, and Catholic canon, who formulated a model of the universe that placed the Sun rather than Earth at its center.
Copernicus or OAO-3 (Orbiting Astronomical Observatory 3), also mentioned as Orbiting Astronomical Observatory-C, [1] [2] was a space telescope intended for ultraviolet and X-ray observation. After its launch, it was named Copernicus to mark the 500th anniversary of the birth of Nicolaus Copernicus in 1473.
Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. [4] The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B, which shared the same orbital plane. Two more satellites, Sentinel-1C and Sentinel-1D are in development.
Copernicus (Selenochromatic Image) with satellite craters. By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Copernicus.

The heliocentric model also resolved the varying brightness of planets problem. [65] Copernicus also supported the spherical Earth theory with the idea that nature prefers spherical limits which are seen in the Moon, the Sun, and also the orbits of planets. [66] Copernicus furthermore believed that the universe had a spherical limit. [66]
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
