it means that the sun (Helios in Greek) is at the centre of the solar system, with all of the planets, including Earth, in orbit around it.
It means that the sun (helios in greek) is at the centre. This is what we know to be true, but for many years people thought that the earth may be at the centre of the solar system (a geocentric system), with the sun orbiting the earth.
Because it is the largest star in our solar system.
why do we say that the solar system is an orderly arangement of heavenly bodies
There is soil on Earth, and Earth is part of the solar system, so you could say that soil is part of the solar system.
The planets are part of the makup of the solar system. I guess you could say the sun provides light for the planets and gravety that holds them to the solar system.
The geocentric system was the first model of our solar system-dating back to the times of Aristotle and is best know as the Ptolemaic system after the Greek philosopher Ptolemy. This model predicted a earth-centered system hence geocentric and it was the most favorable until about the late 15 hundreds if my memory is serving me well. however some astronomers were not concurring to the geocentric model, in the light of that a guy known as Nicolaus Copernicus devised a secret(this was against the teachings of the church and it was death punishable) heliocentric system with the sun at the center of our solar system and that was later mastered by a lot of fellows like Galileo and Kepler.. Some Facts about this1) Copernicus was smart enough to only publish lying on his bed of death2) Galileo was held under house arrest for the last 10 yrs of his life for publicising the heliocentric system The word "helios" in Greek means "sun." Heliocentric means that the sun is at the center. A heliocentric system is one in which the planets revolve around a fixed sun. Thus Mercury, Venus, the Earth, Mars, Jupiter and Saturn all revolve around the sun.This theory was first proposed by Nicolaus Copernicus. Copernicus was a Polish astronomer. He first published the heliocentric system in his book: De revolutionibus orbium coelestium.Further digging showsWhile Nicolaus Copernicus is often credited as being one who pushed heliocentrism to the forefront of modern astronomy it was actually Aristarchus of Samos who argued the idea of a heliocentric model nearly 1800 years earlier!
If you're asking WHY the solar system is called that, it is because the sun (solar) is the center object controlling the orbits of the individual planets. As to the meaning of life, or why it exists, well, let's just say God plays billards alot!
Le système solaire
that the sun is in the middle of the earth
because i say so!
They don't. Do some reading on the Solar System (for example, in Wikipedia); the current estimate for the age of the Solar System is between 4-5 billion years.They don't.

He is worth knowing about because he revived the Heliocentric modelSome say that he reveled the Heliocentric model but he didn'tBut he was the first person to try to push people to to believe in the Heliocentric model
