From the perspective of our solar system, the Sun doesn't move; everything else in the solar system moves around it.
In reality, there are NO "fixed points" in the universe; EVERYTHING is moving. The Moon moves around the Earth, the Earth moves around the Sun, the Sun (and our entire solar system) orbit the center of the Milky Way galaxy. All the other galaxies are also moving, and it doesn't make any sense to assume that the Milky Way isn't moving as well - but there is no "stationary spot" in the universe that we can use to measure the Milky Way's movements.

How does the heliocentric model of the universe work?
This model simply claims that Earth and the other planets revolve around the Sun.It is clear, nowadays, that the Sun is the center of the "Solar System", but not of the Universe. It is also clear that the Sun is not the EXACT center - the Sun and the planets move around the center of mass of the Solar System, which is very close to the Sun due to its larger mass, compared to other objects.
Why are we a heliocentric solar system an not a geocentric solar system?
because heliocentric means " sun is the center of the universe" and geocentric means "earth is the center of the universe" so if you know about the solar system you should know that the sun is the center of the solar system
Difference between geo- and helio-centric model?
Geocentric is that the earth is the center of the universe and heliocentric is the sun is the center of the universe. can it be nothing.
Why does Aristarchus idea that the Sun is much larger than the Earth support the heliocentric theory of the solar system?
According to modern understanding, the planets, and the Sun, move around the Solar System's center of mass. Since the Sun is much more massive than the planets, this center of mass is very close to the Sun. If the Sun is much larger than any of the planets, it seems likely that it also has a greater mass - assuming that their respective densities are somewhat similar. And indeed, this is the case here.
Who reinvented or rediscovered the heliocentric theory?
The original idea (at least, the earliest of which we're aware) that the Earth circled the Sun was proposed by Aristarchus of Samos, a Greek astronomer and mathematician. But the Aristotle's idea that the Sun circled the Earth was more "obviously apparent" and became accepted as fact. The reintroduction of the heliocentric theory by Copernicus, supported by more accurate celestial observations, came almost 1700 years later.

Is the planet move around the sun?
Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.
Does the sun move around the earth once every year?
No, the heliocentric theory states that the Earth revolves around the Sun once each year.
What dos Heliocentric mean?
Having the sun as the center.Measured from or considered in relation to the center of the sun: "heliocentric distance".
What is sun-centred?
Heliocentric means sun-centered.
What is at the center of heliocentric model?
In the Heliocentric model, the SUN is in the center. The word 'Helio' refers to SUN. 'Centric' refers to center. So its ' SUN-Center.
