Ptolemy sought to explain planetary movements by stating that every planet in the solar system revolved around the sun. Astronomers began to question this explanation when they realized that planets often appeared to be moving backwards relative to Earth.
why do we say that the solar system is an orderly arangement of heavenly bodies

No. There is one star in our solar system, and no other solar systems within it.
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.

Copernicus' view was that the sun was the centre of the solar system. He believed everything revolved around the sun in circular orbits. Ptolmey on the other hand placed a static Earth at the centre with the planets and the sun orbiting the earth.Copernicus thought that the solar system revolved around the sun and not the Earth.

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.
