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.
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.

No. There is one star in our solar system, and no other solar systems within it.
There are no exoplanets in our solar system. By definition, an exoplanet is a planet that is not in our solar system.
Our Solar System
Its a planet, NOT a solar system.
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.
Because it is the largest star in our solar system.
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.

Ptolemy is a person. he is a famous astrologist
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.
because i say so!
"Our solar system." The "part of our galaxy" that's in our solar system is the solar system.
No. it is a Satellite [ or say Moon ] for Jupiter; the largest moon in our solar system.
So we can look around and say. "My britches are too small"
