Which of the following is not a member of the solar system?

Options

A. An asteroid
B. A satellite
C. A constellation
D. A comet

Answer

To determine which of the following is not a member of the solar system, we need to analyze each option provided:

1. **Asteroids**:
- Asteroids are rocky bodies that orbit the Sun. They are primarily found in the Asteroid Belt, which lies between the orbits of Mars and Jupiter. Therefore, asteroids are indeed members of the solar system.

2. **Satellites**:
- Satellites can be natural (like moons) or artificial (man-made). Natural satellites orbit planets, and many planets in our solar system have moons. Artificial satellites are sent into orbit around Earth and other celestial bodies. Hence, satellites are also part of the solar system.

3. **Constellations**:
- Constellations are groups of stars that form recognizable patterns in the night sky. They are not part of the solar system; instead, they are collections of stars that may be located far away from our solar system. Each star in a constellation can have its own planetary systems, separate from ours. Therefore, constellations are not members of the solar system.

4. **Comets**:
- Comets are icy bodies that release gas or dust. They have long tails and orbit the Sun. Comets are part of the solar system as they travel around the Sun.

Based on this analysis, the correct answer to the question "Which of the following is not a member of the solar system?" is **Constellation**.

### Step-by-Step Solution:
1. Identify the options given (Asteroids, Satellites, Constellations, Comets).
2. Analyze each option to determine if it is a member of the solar system.
- Asteroids: Yes, they are members.
- Satellites: Yes, they are members.
- Constellations: No, they are not members.
- Comets: Yes, they are members.
3. Conclude that the option that is not a member of the solar system is **Constellation**.
