If we draw t zperpendicular to s t, and ifwe suppose that initially theplanet was projected in the direction t z, the attractionof the sun at s will deflect the planet from the line tzwhich it would otherwise have followed, and compelit to move in a curved line. The particular curvewhich the… … Planetary Orbits. 79 Let us now consider the effect which the attrac-tion of the sun will have upon the velocity of theplanet.
