Galaxy [DeVore]

A star-cluster or group of stars. The Sun and its system are a unit in the Milky Way Galaxy, which moves around a gravitational center that must be in the vicinity of 0° Capricorn, as viewed from the Earth, geocentrically considered. In that event, the Sun's path, at right angles to this point, must be along. the line between 0° Aries and 0° Libra, which the Earth intersects at the Equinoxes. The inclination of the Earth's axis, that causes this phenomenon, may thus be due to the inclination of the plane of the Earth's orbit, or in response to the attraction from the gravitational center that bends the Sun's travel into an orbit, or a combination of these and other influences.
