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.
