Answer: A Constellation
| Member of solar system | Type | Description |
| Sun | Star | The central star of the solar system, providing light, heat, and energy through nuclear fusion. |
| Mercury | Planet | The closest planet to the Sun, with extreme temperatures due to its lack of atmosphere and thin crust. |
| Venus | Planet | Known for its thick atmosphere and extreme greenhouse effect, making it one of the hottest planets. |
| Earth | Planet | Our home planet, characterized by a diverse biosphere, oceans and atmosphere favorable to life. |
| Mars | Planet | Often called the “Red Planet,” with a thin atmosphere, has polar ice caps and evidence of water flows. |
| Jupiter | Planet | The largest planet in the solar system, known for its massive size, strong magnetic field, and bands of clouds. |
| Saturn | Planet | Recognized by its prominent ring system and numerous moons and has a low density due to its gas composition. |
| Uranus | Planet | A gas giant with a unique tilted axis of rotation, giving it extreme seasons and a faint ring system. |
| Neptune | Planet | Another gas giant with a deep blue color, strong winds and the farthest distance from the Sun among planets. |
| Pluto | Dwarf Planet | A dwarf planet formerly classified as the ninth planet, orbits in the Kuiper Belt beyond Neptune. |

| Asteroids | Small Bodies | Rocky bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter. |
| Comets | Small Bodies | Icy bodies that develop tails when they approach the Sun due to solar radiation sublimating their ices. |
| Kuiper Belt Objects | Small Bodies | Objects beyond Neptune, including Pluto and Eris, found in the Kuiper Belt, a region of icy debris. |
| Oort Cloud Objects | Small Bodies | Hypothetical cloud of icy bodies far beyond Pluto |
