Final answer:
All worlds in our solar system commonly orbit around the Sun, a characteristic ensured by the Sun's gravitational influence. While Earth is particularly notable for its habitability and biosphere, characteristics such as liquid water, atmospheric composition, and magnetic fields vary greatly among planetary bodies.
Step-by-step explanation:
The correct answer to the question is c) Orbiting around the Sun. All objects in our solar system, including planets, dwarf planets, moons, asteroids, and comets, share the common characteristic of orbiting around the Sun. This is because the gravitational pull of the Sun keeps these bodies within its solar system. Characteristics such as the presence of liquid water, similar atmospheric composition, and Earth-like magnetic fields are not shared by all worlds in our solar system. Earth is unique with its abundant liquid water and diverse atmosphere. Magnetic fields differ greatly among the various planets and many smaller bodies lack substantial atmospheres altogether.
Astronomers believe that all objects in the solar system formed from the same nebula known as the solar nebula. This belief is supported by the observation that there is a general chemical composition pattern that indicates a temperature sequence from hot near the Sun to cooler as we move outward. However, Earth stands out for its ability to support a photosynthetic biosphere thanks to its surface liquid water and moderate temperatures within the habitable zone, something not shared by other worlds.
