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.
Nicolaus Copernicus (1473-1543) is generally acknowledged as defining the heliocentric model, although Aristarchus of Samos (310-230 BC) was one of the earliest proponents.
The astronomer (and chief developer of the telescope) Galileo Galilei (1564-1642) was labeled as a heretic for his espousal of Copernicus' theory, but enabled it to achieve acceptance by modern science.
The sun centered theory also called the heliocentric theory states that the sun is the center of the solar system and the planets revolve around the sun. This theory was developed by Copernicus and later proven by Galileo with the aid of a telescope.
This is referred to as "heliocentric", sun centered. This means the sun is the center of the solar system. All the planets orbit around the sun instead of all the planets and sun orbiting around the earth. This theory was first proposed by Copernicus.
A heliocentric theory. It claims that the sun is in the center and all the planets orbit it.

The earth has seasons mainly because of the tilt to the earth towards or away from the sun. Contrary to popular belief, the distance from the sun caused by Earth's elliptical orbit only makes a minuscule difference in climate.

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.
It was published in 1543
The heliocentric model is sun-centered. The geocentric model is earth-centered.

That would be the moon. We've never thought of it that way ... the only object whose status didn't change between the geocentric and heliocentric model. Thanks for showing it to us.
It means centered around the Sun. From the Greek helios "sun", kentron "center".
