Solar centric or more usually heliocentric put the sun at the centre of the universe as opposed to the earth at the centre. We now know this to be inncorrect though the sun is at the centre of the solar system
Aristotle had thought that the Earth was the Geo-centric or the center of the universe and everything circled or revolved around it. Copernicus thought that the Sun is the center of the universe. Copernicus' idea is called Helios-centric.
Nicolas Copernicus came up with the Copernican Model of the Solar System. It described the Earth orbiting the Sun, displacing the Ptolemaic model, which placed the Earth at the centre of the universe, and formed the basis of what we know of the solar system to this very day. This is called a Heliocentric model of the universe, from Helios (the greek god of the sun, often used to show the sun himself), and Centric, (meaning around, where we get our word centre from).
Nicolaus Copernicus
Copernicus was the first to show, in a systematic and mathematical way, that a helio-centric solar system made astronomical observations easier to understand. Ptolemy's system worked (well, sort of) in explaining what we see, but it was incredibly complicated.
Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.
Copernicus mistakenly thought that our earth was the center of our universe, with the sun and other planets orbiting earth.
Solar centric is the Copernican theory that Earth moves around the Sun
Nicolas Copernicus believed that the sun was the center of the solar system. Before that most believed that the Earth was the center of the universe.
Nicolas Copernicus developed the model of the solar system that says that the sun is the center of the universe and that all of the other planets are orbiting it.
Everybody did until Nicolaus Copernicus discoved that the Earth wasn't the center of the universe
'Helio' is Greek for Sun and 'Centric' is obviously being in the middle of things. Heliocentric is to describe the way the Solar System is, meaning the Sun is the centre of our Solar System. In earlier times, the Earth was thought to be the centre of the universe, but now we know that is not true. If the Earth wasthe centre, it would be a Geocentric Universe. Rani XD
The astronomer credited as the first to theorize that the planets orbit around the Sun (heliocentrism) is Nicolaus Copernicus. He developed the heliocentric model of the solar system, which proposed that the Sun was at the center and the planets, including Earth, revolved around it in circular orbits. This theory was a departure from the earlier geocentric model, which posited that Earth was at the center of the universe and everything orbited around it. Copernicus's work laid the foundation for the modern understanding of the solar system's structure and motion.
