Apogee, Perigee and Orbit of Earth

doorenochhaga urvyaa: karnavasaannochhago nikate

  When a planet is at a distance of 6 signs from its apogee, it is said to be at the perigee or neecha. When a planet is at the apogee, it is farthest from the earth when at the perigee, it is nearest to the earth. This is so because of the length of the hypotenuse in each case (Sishyadhi vruddhi Tantra 14-10)]]>
