The statement that could be added because it accurately describes our solar system in the Milky Way is:
"Our solar system will always be part of the Milky Way."
The other statements are either inaccurate or misleading. For instance, our solar system is not located in the center bulge of the Milky Way; it is situated in one of the spiral arms. While there are numerous other star systems, it isn't accurate to say our solar system is one of close to a billion systems that might have a habitable planet like Earth without more context. Lastly, while our solar system does have a star at its center (the Sun), many other solar systems also have stars at their centers.
