Because of the laws of gravity.
Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
Johannes Kepler.
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 planets stay in orbit because of the gravitational attraction between the individual planets and the sun. Their rotational velocity makes them stay in a stable orbit instead of spiraling into it.

Gravity - from the sun.
The Sun has such a gigantic mass that it dominates the nearby volume of space.Not all bodies do orbit the Sun; there are comets that get pulled in by the Sun's gravity but then leave the solar system (comest on hyperbolic paths).Many smaller bodies also orbit their parent planets (we then call them moons).What else could the planets orbit around? Part of the definition of a planet is that it orbits the Sun! So planets by definition orbit the Sun! If they did not orbit the Sun they would not be called planets!

The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
