Question

explain why all of these objects are considered part of our solar system.

Explanation:

All these objects are part of the solar system because they are gravitationally bound to the Sun, orbit (or are orbited by objects that orbit) the Sun, and formed from the same giant interstellar gas and dust cloud that created the Sun. This includes planets, dwarf planets, asteroids, comets, and natural satellites that fit this gravitational and formative criteria.

Answer:

These objects are considered part of our solar system because they are gravitationally bound to the Sun, follow orbits (or are associated with orbiting bodies) centered on the Sun, and originated from the same primordial solar nebula that formed the Sun. This encompasses planets, dwarf planets, asteroids, comets, and natural satellites shown in the diagram.
