In ancient times, astronomers believed that the Earth was the center of the universe, and that the sun, moon, and planets revolved around it. This geocentric model was supported by the naked-eye observations of the heavens, and it was not until the 16th century that astronomers began to challenge it.

Nicolaus Copernicus, a Polish astronomer, was the first to propose a heliocentric model of the solar system, in which the sun was at the center and the Earth and other planets revolved around it. Copernicus's model was based on mathematical calculations, but it was not widely accepted at the time because it contradicted the geocentric model that was supported by the Church.

In the 17th century, Galileo Galilei, an Italian astronomer, used a telescope to observe the heavens and provide further evidence for the heliocentric model. Galileo's observations included the discovery of the four largest moons of Jupiter, which he named the Galilean moons. Galileo's work was instrumental in the overthrow of the geocentric model and the acceptance of the heliocentric model.

Johannes Kepler, a German astronomer, further developed the heliocentric model by proposing that the planets move in elliptical orbits around the sun. Kepler's laws of planetary motion were based on the data collected by Tycho Brahe, a Danish astronomer. Kepler's laws were a major breakthrough in astronomy, and they helped to lay the foundation for the development of modern physics.

In the 18th century, Isaac Newton, an English physicist, developed a theory of universal gravitation that explained the motion of the planets and other celestial objects. Newton's theory of gravity was a major step forward in our understanding of the universe, and it is still used today to calculate the orbits of planets and other celestial objects.

The development of planetary astronomy has had a profound impact on Western thought. It has led to a greater understanding of the universe and our place within it. It has also led to the development of new technologies, such as the telescope, and new scientific methods, such as the use of mathematics to describe the natural world.

Planetary astronomy continues to be an important field of scientific research today. Astronomers are using telescopes to study planets in other solar systems, and they are using space probes to explore the planets in our own solar system. The study of planetary astronomy is helping us to understand the origins of the universe, the evolution of life, and the possibility of life on other planets.
