Geocentric vs Heliocentric
The study of everything about universe is
called astronomy. As a result of
Ptolemy, an astronomer, he invented the geocentric model. He believed that each
planet orbited around the Earth. Geocentric model is a model of the solar
system that has the earth is in the center and everything goes around it. Until
the 16th century, everyone believed this. Nicolas Copernicus was a Polish
astronomer who believed that the earth and other planets revolved around the
sun. This theory was called heliocentric theory. Heliocentric model is a model of the solar
system that has the sun is in the center and everything goes around it. Galileo
Galilee was an astronomer who invented the telescope and changed our
understanding of the universe. He supported the Copernicus theory and he was
rejected the Ptolemy theory. He believed of the heliocentric model is a theory
which has the sun in the center and the earth goes around the sun and these
takes 365 days and this process called revolution. The
movement of one body around another; such the earth in its orbits around the
sun. Galileo Galilee he was forced to say that the heliocentric model was
wrong. He was arrested by the Catholic Church.
After his death, most of his ideas were proven correct including the
heliocentric model.
