No, it was Copernicus who proposed for the first time a complete model which had the Sun at the centre. At that time a 'model' was a geometrical construction that had the planets on small individual circular orbits (epicycles) that themselves travelled round on the main orbits, which were also circular.
Most of the planets had more than one epicycle to explain both the inclination of the orbit to the ecliptic and also the variation in distance from the Sun, which from the time of Kepler onwards was explained by the fact that the orbits were elliptical.
Galileo put forward the Copernican model, first as a teaching aid, and then later as the absolute truth, and this later step put him into conflict with the church authorities.
Kepler's model used the heliocentric concept but with elliptical orbits, and this was later demonstrated as the best model after scientific discoveries well after the time of Kepler and Galileo, by Newton, Laplace and others.

Who was first to say the sun is at the center?
Ancient Greek philosopher Aristarchus of Samos is the first known individual to propose that the Sun is at the center of the solar system. His heliocentric model challenged the prevailing geocentric view of the universe.
Who was the first astronomer to see the phases of Venus?
Galileo Galilei was the first astronomer to see the phases of Venus in 1610, providing evidence for the heliocentric model of the solar system proposed by Copernicus.
Who was the first 16th century scholar to propose the heliocentric theory?
Nicolaus Copernicus, a Polish mathematician and astronomer, was the first scholar in the 16th century to propose the heliocentric theory in his book "De revolutionibus orbium coelestium" published in 1543.
Galileo contribute to the solar system?
Galileo had a theory, it was that the earth was NOT in the centre of the solar system like everyone thought, he made the first telescope and proved everyone wrong by looking into space and seeing that the sun was in the centre of the solar system, not the earth, doing this he also invented the telescope.

What did copernicus descover?
Copernicus was the first to propose the Heliocentric theory, the correct theory that the Sun, not the Earth, is the center of the solar system.

Was Aristotle the first to propose the sun was the center of the universe?
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.
Who said the planet goes around the solar system?
Galileo Galilei is credited with the observation that the planets orbit the sun rather than the sun orbiting the Earth. However, Aristarchus of Samos proposed the concept first in the 3rd century BC.
Who was the first 16th century scholar to propose the heliocentric theory?

Galileo was the first astronomer to use what?
Galileo was the first astronomer to use a telescope to observe celestial objects in detail. This helped him make groundbreaking discoveries such as the moons of Jupiter and the phases of Venus, which provided strong evidence for the heliocentric model of the solar system.
Who was first correct on solar system Copernicus or Galileo?
Nicolaus Copernicus was the first to propose a heliocentric model of the solar system in the 16th century, which placed the Sun at the center with planets orbiting around it. Galileo Galilei supported Copernicus's ideas and used his observations through a telescope to provide further evidence for this model in the early 17th century.
