If you imagine these bodies to be revolving in a plane around the Sun and yourself to be standing within the Sun, the motions of these bodies will appear almost uniform and always in one direction.
Were the orbits of the planets circular and the Sun holding the centre of the circle, their motions would be constant, that is to say, always in the same direction and at the same rate.
The subsequent discovery of the planets Uranus and Neptune by Herschel and Adams, widened the field of research and gave to later astrologers the clue to much that hitherto had been imperfectly understood.
Not that these discoveries overturned the whole system of astrology, as some have imagined and foolishly stated, or that they negatived the conclusions drawn from the observed effects of the seven anciently known bodies of the solar system, but it became possible after a lapse of time to fill in the blank spaces and to account for certain events which had not been traced to the action of any of the already known planets.
The Earth follows the same laws as all other bodies of the same system.
But if we imagine the Earth to be stationary in space and the centre around which the planets revolve, their motions present several irregularities.
The equation itself depends on the eccentricity of the orbit, that is to say, its relation to a circle drawn around the same focal centre.But the orbits are elliptical, and the Sun holds a position in one of the foci of each ellipse.Consequently the planets are at times further from the Sun than at others, and they are then said to be in their aphelion, the opposite point of the orbit where they are nearest to the Sun being called the perihelion.When at aphelion the planets move slower, and when at perihelion they move quicker than at the mean distance.Astronomers employ an imaginary circular orbit for the planets, in which they move at an uniform rate of velocity, which is called the mean motion.
