A sun-centered solar system is called a heliocentric solar system. In a heliocentric system, the Sun is at the center and the planets, including Earth, orbit around it. This model was proposed by Nicolaus Copernicus in the 16th century, replacing the earlier geocentric model where Earth was believed to be the center of the universe.
A long time ago, people believed that the Earth was the center of the universe, a theory known as the geocentric model. This idea was eventually replaced by the heliocentric model, which places the Sun at the center of the solar system, proposed by astronomers like Copernicus and Galileo.
heliocentric
The Sun-centered or heliocentric model of the solar system is called the Copernican model (after Copernicus) and more closely matches the modern astronomical notions. By contrast, the geocentric or Earth-centric model is often called the Ptolemaic.
The sun-centered model of the solar system states that the planetes orbit the sun. In this model, everything in the solar system orbits the sun and so the sun is the center, hence the name. While all scientists accept this model today, there was a long period of time where people believed that everything in the solar system orbited the Earth. This was called the geocentric model of the solar system.
The Earth-centered solar system was thought to be sun-centered in the 16th century by astronomers such as Nicolaus Copernicus. Copernicus published his model in 1543, proposing that the Sun, not the Earth, was the center of the solar system. This heliocentric model eventually gained acceptance over the previously held geocentric model.

Geocentric means considering the Earth as the center.
Before the heliocentric model gained acceptance, many ancient astronomers believed in a geocentric universe where the Earth was considered the center of the solar system.
Ancient astronomers like Ptolemy believed in a geocentric model, where the Earth was at the center of the universe and all celestial bodies revolved around it. This view was later challenged by Copernicus, who proposed a heliocentric model placing the Sun at the center of the solar system.
The heliocentric model proposed by Nicolaus Copernicus in the 16th century positioned the Sun at the center of the solar system, with the planets, including Earth, orbiting around it. This model replaced the geocentric model which had Earth at the center.

Not completely, but it was closer than the geocentric system.
A long time ago, people believed that the Earth was the center of the universe, a theory known as the geocentric model. This idea was eventually replaced by the heliocentric model, which places the Sun at the center of the solar system, proposed by astronomers like Copernicus and Galileo.
The geocentric model of the universe, where Earth is believed to be at the center, was largely renounced in the 16th century with the work of astronomers like Nicolaus Copernicus and later Galileo Galilei. This marked the beginning of the acceptance of the heliocentric model, where the Sun is at the center of the solar system.
