PLANETS AND THEIR SATELLITE SYSTEMS
If we compute the speeds of satellites about their primaries in the solar system and compare them with the velocities in their orbits of the planets themselves, a striking parallelism stands displayed between the several systems.
This is shown in the following table of them:
| Mean Speed, Miles A Second | Parabolic Speed at Orbit | Ratio Speed Sat. About Primary to Planet's Speed in Orbit | |||
| of Primary in Orbit | of Satellite about primary | Miles a second. | |||
| V | v | ||||
| Jupiter | 8.1 | 11.5 | |||
| Sat. 1 | 10.7 | 1.32 | |||
| 2 | 8.5 | 1.05 | |||
| 3 | 6. 7 | 0.83 | |||
| 4 | 5.1 | 0.63 | |||
| Saturn | 6.0 | 8.5 | |||
| 1 | 9.0 | 1.50 | |||
| 2 | 7.9 | 1.31 | |||
| 3 | 8.2 | 1.36 | |||
| 4 | 6.3 | 1.05 | |||
| 5 | 5.3 | 0.89 | |||
| 6 | 3.5 | 0.59 | |||
| 8 | 2.0 | 0.34 | |||
| Uranus | 4.2 | 5.9 | |||
| 1 | 3.5 | 0.82 | |||
| 2 | 2.9 | 0.70 | |||
| 3 | 2.3 | 0.54 | |||
| 4 | 2.0 | 0.47 | |||
| Neptune | 3.4 | 4.8 | |||
| 1 | 2.7 | 0.81 | |||
The relations here disclosed are too systematic to be the result of chance.
