Heliocentric(sun-centered)and Geocentric(earth centered) were too different theories about the motions of the stars and planets. In the heliocentric view the sun is fixed and the earth(as well as the other planets) revolve around the sun in elliptical orbits. In the geocentric view, the earth is fixed and the sun and the other planets rotate around the earth. Since one cannot define a permanent origin and coordinate system in nature both views are correct(this may sound odd to people who were born after the time of Kepler but just hear me out). Since the definition of an inertial reference frame is arbitrary(as shown by Einstein's theory of relativity) one can set the earth or the sun in the center of that reference frame. If one were to use the sun as the center of the reference frame, the earth(and the other planets) follow simple elliptical orbits that are easy to compute and understand. On the other hand if one were to use the earth as the center of the reference frame, then the sun and the other planets no longer follow nice easily solvable orbits(also the concept of gravity resulting in planetary orbits gets thrown out the window), however the predictions of orbit are the same. Simply put: The sun is considered the center because its gravity combined with planetary inertia is what is understood to create the orbits that we see today. Hope you found that interesting
The Sun rotates on its own axis from west to east, just like the Earth (counter-clockwise as seen from the arbitrary north, above the plane of the solar system).
However, the Sun is a ball of gaseous plasma, not a solid body. So, as is the case with the gaseous atmospheres of Jupiter and Saturn, the exterior of the Sun rotates at different speeds depending on its solar latitude.
The polar areas of the Sun rotate about once every 34.4 Earth days. The equatorial regions travel the fastest, completing a rotation in just 25.05 days.
Earth has life and soil. the sun is flaming and is a star. earth has water. sun has extreme tempatures.
Earth centred is the geocentric model, which is not true. The sun centred model is the heliocentric model which we now know is true.
"Heliocentric" is Latin for "Sun centered".
It means the same thing.
Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate of gas and plasma, different parts of the Sun spin at different rates.

The weird thing about the Sun's rotation - as compared to Earth's rotation - is precisely that it is a differential rotation. That means that at the equator, the Sun rotates faster than near the poles. There is some recent evidence that the inner and outer cores of Earth do indeed spin at different rates and at different rates compared with the rest of the planet.
When the earth moves, the sun is left behind, so half of the earth is not facing the sun. Dumbo

The sun is at different point of the earth.

The rotation of the Earth produces days and nights, because different areas are illuminated at different times. The orbit of the Earth creates years because the period of rotation dictates how long it takes for all the seasons to pass by. The rotation rate of the Sun does not affect either the days or the years of Earth.

It has to do with the rotation of the earth and how far away it is from the sun during the different seasons.
1. Rotation (earth rotates on it's axis) 2. Orbit (earth orbit's arount the sun)
