224. If the whole coagulated æther of the solar system be so small in quantity, that when extended around the sun in a planetary track or course, it still does not become solid; so also can the orbitar ring not persist, but it contracts itself through light, rotation and the peculiar excited gravity into a _globe_. This globe continues to rotate, as it did when under the conditions of orbitar ring, of hollow globe and as æther; i. e. it pursues a course around the sun. The peripheric globe travels necessarily in the same plane in which the sun rotates. This is therefore called the zodiac. This globe rotates also around its own axis and virtually in the same direction, according to which it performs its course or the sun rotates. A globe coursing and rotating around the sun in its equatorial plane and in its direction is called _planet_. 225. At the first aggregation of the mass of the planetary ring into a planetary globe, the latter was still very much extended, the earth extending beyond the moon. The mass was thus gaseous. What happened in the great globe of æther, of which the sun has become the centre, happens also here. An opposition of centre to periphery again originates; and a subordinate sun and new orbitar rings are formed. If the mass of the planetary equatorial ring be only small and consequently rare, it rolls into a globe and together with this into _moons_. 226. If it be much, consequently so dense, that it coheres, it remains stationary, and is _Saturn's ring_. 227. This is the genesis of the planetary system, but everything has become, and remained as it became, at one stroke. The moon can never have existed as an orbitar ring around the earth in time, or else it had been solid. Being once solid, it can no more coagulate into a globe. Still less, however, have the planets originated from conjoined moons. From whence then have the moons come? The solar system has not arisen mechanically, but dynamically; it has not become what it is by being projected or hurled from the hand of God, nor by impulses and aberrations; but by polarization according to eternal laws, according to the laws of light. 228. As a necessary number of planetary productions exists, so also is their magnitude, distance and velocity a determinate one. No planet, whatever its situation, has attained that by chance. Were the earth larger, it must also have occupied some other place, and have had another velocity, another density of mass, &c. 229. The coagulating matter of æther must collect into a larger mass in the centre than in the periphery. The centre will exist everywhere, and the periphery comes only to its behalf as if it were a scaffold or prop only to existence. The sun can only be the principle of the determination of the planets by the preponderance of its mass. Our sun comprises above 700 planetary systems in itself.
