Transcribed Image Text:**Table A-11: Principal Satellites of the Solar System**
This table provides detailed information on the principal satellites of various planets in the Solar System. It includes data about each satellite's radius, distance from its primary planet, orbital period, orbital eccentricity, and orbital inclination.
**Columns**:
1. **Primary**: The planet around which the satellite orbits.
2. **Satellite**: The name of the satellite.
3. **Radius (km)**: The radius of the satellite in kilometers.
4. **Distance from Primary (10^3 km)**: The average distance from the satellite to its primary planet, measured in thousands of kilometers.
5. **Orbital Period (days)**: The time it takes for the satellite to complete one orbit around its primary planet, measured in days.
6. **Orbital Eccentricity**: A measure of how much the orbit deviates from being circular. A value of 0 indicates a perfect circle.
7. **Orbital Inclination**: The tilt of the satellite’s orbit relative to the planet’s equator.
**Notes**:
- The symbol “~” indicates approximate values.
- **Orbital Inclination** is measured relative to the planet’s equator.
**Details for Each Planet**:
- **Earth**:
- Moon: Radius 1738 km, 384.4 x 10^3 km from Earth, 27.32 days orbital period, orbital eccentricity 0.055, inclination 18.3°.
