The ruling thought of how the solar system was put together had for several hundred years had the Earth in the middle. Then came the heliocentric theory and put the Sun - not the Earth - in the middle. This annoyed the Church, which thought that humans - the finest of God's Creations - should be in the middle.
Copernicus produced the first heliocentric theory of the planets' movements among the stars in1543. He used the idea that the Sun is at the centre, plus a whole lot more detail that has now been superseded. The modern theory is that of Kepler (1609), which resembles the Copernicus model only in so far as it is also heliocentric.
The problem was, he didn't just support Copernicus's idea, and he did not stick to teaching it as a theory, as the church allowed him to do. His problem was that he promoted it aggressively as the absolute truth, and that is what put him on a collision course with the Vatican. He was tried for heresy because he was held to be trying to reinterpret the Bible. Copernicus's theory, as promoted by Galileo, was eventually replaced by Kepler's theory, but the idea of having the Sun at the center was retained. In the 18th century the discovery of the law of gravity and the laws of motion showed that Kepler's model was very close to reality, and it's the model in use today with slight modifications from relativity.
The Bible is written from an implicitly geocentric viewpoint, so if we take the Bible as the ultimate authority on everything, then it would be wrong to come to other conclusions such as the heliocentric theory, merely by observing the way the universe actually is. Incidentally, although Galileo did support the heliocentric theory, it was originally proposed by Copernicus. It isn't Galileo's model. Galileo did contribute to this theory with his astronomical observations, however.
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.
In the following order: Heliocentric theory of the solar system (Aristarchus of Samos, 270 BCE) Natural Selection (Darwinian evolution, 1858) Theory of the hydrogen atom (as a small negatively charged particle inside a larger positively charged particle, 1904, the plum pudding model) Theory of relativity (special relativity, 1905) Theory of relativity (general relativity's initial paper on the acceleration of objects within the framework of special relativity, 1907) Theory of the hydrogen atom (as a small particle orbiting the atomic nucleus, 1909, the Rutherford or Planetary model) Theory of the hydrogen atom (as an "electron cloud" surrounding the atomic nucleus, 1913, the quantum mechanical or Bohr model) Theory of relativity (general relativity and its ability to warp space-time, 1915) So heliocentrism was, by about two millenia, the first. Relativity and the model of the hydrogen atom are intricately intertwined, so which came first depends on what you mean specifically.

we just wouldn't have figured out that our universe aws heliocentric until a little later Galileo agreed with Copernicus on his theory so we would have found it out still just a little later
Oh, dude, Copernicus was all about that heliocentric model, you know, like the sun being at the center of the solar system and all. He totally disliked the idea of Earth being the center of everything, like, so last season. I mean, who wants to revolve around Earth when you can revolve around the sun, right?
Nicolaus Copernicus was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe. So yes I guess you can say he was a scientist.
Copernicus published an alternative model of the planets' movement in 1543 that had the Sun at the centre. It was the first heliocentric model. It used orbits based on combinations of circles, as the ancient Ptolemaic system had done, which was geocentric. In Copernicus's model the paths followed by the planets were less complicated, but other than that Copernicus had no way of proving if it was right or not at that time, so it isn't known whether he believed in it.

In a book called On the Revolutions of the Heavenly Bodies (that was published as Copernicus lay on his deathbed), Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system. The ordering of the planets known to Copernicus in this new system is illustrated in the following figure, which we recognize as the modern ordering of those planets.For this reason, a heliocentric system is the Solar System with the sun in the center, so there is not an "opposite".
Even more so. It's not even a theory anymore, it's a proven fact.
Data gathered using Galileo's early telescope, such as observations of the phases of Venus and the moons of Jupiter, provided evidence supporting the heliocentric model. These observations showed that not all celestial bodies orbit the Earth, as previously believed, but instead supported the idea that they orbited the Sun. This challenged the geocentric view and provided observational proof for the heliocentric model proposed by Copernicus.
