...plane in which a planet moves in reference to the ecliptic it is necessary to know (1) the angle of inclination of the plane of the planet's orbit to the plane of the ecliptic : (2) the longitude of the line of intersection of the two planes ; this line of intersection is called... | |

...either an inferior or a superior planet, we must be able to determine: — 1st. The relative position of the plane of the planet's orbit to the plane of the ecliptic ; 2d. The position of the orbit itself in the plane in which it lies; 3d. The magnitude and the form... | |

... therefore prefer the latter, taking account of its variation by the effect of precession, and restoring it, by calculation at every instant, to a fixed position. Now, to determine the situation of the ellipse described by a planet with respect to...
