Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
The universe has infinite shape and infinite size (though it is said (Einstein) that it has). So, it is shapeless as far as the human imagination is concerned.
Ptolemy.
Yes. A solar system, by definition, is a system of objects orbiting a central star. The central star of said system is called a sun.(Note that a common misconception is that the sun of our solar system, Sol, is named "Sun.")
The celestial bodies of our solar system are believed to have formed from the solar nebula. The solar nebula was a giant cloud of dust and gas that was left behind after the formation of the sun.

Well the sun is in the center of our solar system. People have said that in about 5 billion years the sun will dime and that it will expand and eat Mercury and Venus and that Earth will have to much heat.
No one .. It was the other way around the church taught that bull.. I believe it was Copernicus that said the sun was the center of the solar system and for fear of the church didn't publish his work till the end of his life
God Himself made all the universe, and everything that is in it. Comment: You probably mean Copernicus.

To be exact there would be millions upon billions because you said the universe But you're probably searching for our solar system There are 8 planets known to be in our solar system 1mercury. 2Venus. 3 earth. 4mars 5Jupiter 6Saturn 7uranus 8neptune Pluto is left out because its to small to be a planet.
