s orbital distance from Jupiter,in the same proportion; and therefore when the body inFig. 4 arrives at (about) the point m. it will be essen-tially in the same case as at the point w., in Fig. ), viz.:the attraction of the planet, adding its influence to thecentrifugal force, will in the first place cause a deviationtowards the tangential direction outside the circularorbit; a little further on, the attractions of the planetand of the sun will be equal, and the body will move inthe tangential direction, thereby receding from the sunand approaching the planet; thus when the point n. hasbeen reached the more distant and feeble influence of thesun will operate only in diminishing the (increased)velocity, and the cometary body becomes a satellite of theplanet throughout n. a, p., about three-fourths of arevolution, until on arriving at (about) the place ^j. theformer conditions are reversed, and the comet recedingfrom the planet returns to its solar orbit q. b. m.
