Is the sun the only star with a gravitational pull

Our solar system hosts the sun at its center — a star so large that its gravitational pull keeps numerous planets, dwarf planets (such as Pluto), comets and meteoroids orbiting around it.

Explanation:

The sun, which is a million times the size of Earth, is densely packed with mass. Its mass dwarfs that of the Earth. The gravitational pull of the sun is enormous. All of the planets in our solar system revolve around the sun due to its gravitational pull.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
