Why?? what proof is there that states the sun is the center of the solar system?? how do we know this??
The solar system is the group of heavenly bodies that orbits the Sun, which is also known as Sol.
Sol orbits the galactic center, roughly 30,000 light years away.
The Milky way galaxy, of which we are a part is also part of the Local Group...a group of Galaxies that are "near" each other.
Since this is not my area of expertise, I searched Google under the key words "sun center proof solar system" to get these possible sources:

You might also want to search under "heliocentrism proof."
I hope this helps a little more. Thanks for asking.

Thanks for asking.
The understanding that the Sun is the center of the solar system is based on the scientific model known as heliocentrism. Heliocentrism was proposed by ancient Greek astronomers, including Aristarchus of Samos and later developed by Nicolaus Copernicus in the 16th century. This model states that the Sun is at the center of the solar system, and the planets, including Earth, orbit around it.
There are several lines of evidence and observations that support the heliocentric model:
1. Retrograde Motion: One of the observations that can be explained by the heliocentric model is the retrograde motion of planets. Retrograde motion is when planets appear to move backward in the night sky relative to the background stars. This motion can be explained by the relative motion of Earth and the other planets as they orbit the Sun.
2. Planetary Orbits and Kepler's Laws: The precise observations of the motion of planets made by astronomers like Johannes Kepler in the 17th century provided further evidence for the heliocentric model. Kepler's laws of planetary motion, based on these observations, accurately describe the patterns and relationships of the planets' orbits around the Sun.
3. Parallax: Parallax is the apparent shift in the position of an object when viewed from different vantage points. Astronomers can use parallax to measure the distance to nearby stars. The absence of detectable parallax in distant stars indicates that Earth is in motion and orbiting the Sun.
4. Gravitational Pull: Isaac Newton's law of universal gravitation also supports the heliocentric model. This law states that all objects in the solar system, including planets, moons, and asteroids, are influenced by the gravitational pull of the much more massive Sun. This gravitational attraction helps maintain the planets' orbits around the Sun.
These are just a few pieces of evidence that support the heliocentric model. Since this topic is extensively studied and backed by scientific evidence, many resources can provide a more comprehensive understanding of the evidence. You can refer to the sources I mentioned earlier for more detailed explanations and research on the topic.
