No such thing as "helicentric"
The heliocentric theory states that the Sun (helios) is the center of the solar system (or the universe if you are talking about ancient heliocentric theories - before the knowledge of other star systems and galaxies).
Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
The Heliocentric picture of the solar system is a model because it was given as a theory by Copernicus to describe the solar system. In prior centuries people believed that the earth was the center of the solar system.
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
The heliocentric theory was first published by Copernicus.
The hypothesis on how the solar system was formed is known as the solar nebula theory. This theory posits that the solar system formed from a massive, rotating cloud of gas and dust called the solar nebula. Over time, gravity caused the material in the nebula to clump together, eventually forming the sun and the planets.
Geocentrism places Earth at the center of the planetary system. Heliocentrism, correctly, places the sun at the center, hence: the Solar System.
Not exactly, it is a theory about the origin of the Universe; which does include the Solar system...

That was Galileo.He advocated the heliocentric theory of the solar system,proposed by Copernicus.
big bang theory
Catastrophic theory of the solar system suggests that major disruptions or events in the past, such as collisions or close encounters with other celestial bodies, played a significant role in shaping the current structure of our solar system. This theory contrasts with the gradual, slow processes of traditional solar system formation theories.
The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
The Heliocentric Theory states that the Earth and planets revolve around a stationary Sun at the center of the solar system. The Sun is the center of the Solar System.
