CHAPTER TWELVE. THE “RULE OF EIGHT” IN THE COSMOS. SOLAR SYSTEM GROUPS CONTAINING EIGHT MEMBERS.
Many groups of planets or satellites contain specifically EIGHT members.
(1). There are EIGHT Planets, ie:- Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. (Pluto is often counted as a “Trans-Neptunian Object, rather than a “proper” planet.) To confirm this, go to the following web page:-

(2). There are EIGHT LARGE Saturn Satellites. Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion, and Iapetus. To confirm this, go to the following web pages:-

and

(3). There are EIGHT Inner Solar System Bodies. The Sun, Mercury, Venus, Earth, Mars, The Moon, and the two Mars satellites – Phobos and Deimos. To confirm this, go to the following web page:-

(4). Jupiter has EIGHT “Regular” Satellites, ie:- the Four LARGE (“Galilean”) Satellites – Io, Europa, Ganymede, and Callisto. Inferior to these are Four Small Satellites – The “Inner” Satellites (sometimes called The “Amalthean” Satellites). These are:- Metis, Adrastea, Amalthea, and Thebe. To confirm this, go to the following web pages:-

and

(5). The (so called) Two “Ice Giants” – Uranus and Neptune. Uranus has Five LARGE Satellites, and Neptune has One LARGE Satellite. This makes EIGHT LARGE Bodies in all. To confirm this, go to the following web page:-

(6). There are EIGHT Naked-Eye-Visible bodies (ie:- viewing from Earth). The Sun, Mercury, Venus, Earth itself, The Moon, Mars, Jupiter, and Saturn. To confirm this, go to the following web page:-

(7). There are EIGHT LARGE “Satellited” Bodies, ie:- The Sun, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. To confirm this, go to the following web page:-

(8). There are EIGHT High Obliquity bodies in The Planetary System. The Sun (with obliquity to the ecliptic of 7.15 degrees), and the following planets with the following obliquity to their orbits:- Venus 177.4 degrees, and Earth 23.45 degrees, and Mars 25.19 degrees, and Saturn 26.73 degrees, and Uranus 97.86 degrees, and Neptune 29.56 degrees, and Pluto 122.5 degrees. (The only LOW Obliquity planets are:- Mercury 0.5 degrees, and Jupiter 3.12 degrees.). To confirm this, go to the following web page:-
