Our solar system consists of the sun, the planets, their moons, and a variety of smaller objects. The sun is at the center of the solar system, with other orbiting around it. The force of gravity holds the solar system together.

No, our Solar System is not the galaxy. Our Solar System is the Sun, and the planets around it (plus a few other objects, such as asteroids and comets). Our Sun (the center of our Solar System) is a star; in the galaxy there are several hundred billion stars, each of which might be called a solar system. At least if it is confirmed that it has planets - but it has already been confirmed that many stars in our neighborhood have planets.

Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".

If the objects are in orbit around the sun then they are in the Solar System.
