Nicolaus Copernicus formed the idea of a heliocentric universe, where all planets orbit around the sun.
i do it
Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
The sun, does not orbit anything. Because it is the center of the universe, based off of the heliocentric model. Planets, and satelites(moons) do orbit the sun though.

The definition of universe in my opinion is a group of planets that orbit around each other.
Ptolemy put the Earth at the center of his model of the universe , and said that the Sun , the moons , the planets ,the asteroids , comets , and meteors orbit the Earth and the Earth was the center of the universe.
The Sun stays in orbit because of gravity. This is also why all the planets stay in orbit too. Gravity pulls the planets towards the Sun. Without gravity, the planets would be wandering all over the universe.
The Geocentric Theory, or The Geocentric Model, proposes that the Earth is the center of the Universe and all other objects orbit around it.
