According to the law of conservation of energy, I have improved the accuracy of planetary speed at any point on the elliptical orbit.
Planet -------- Perihelion precession ------------ Afar precession (per century)
------------------------------------------------------------------------------------------
Mercury********** 58.404"***************** 32.938"
Venus********** 38.004"****************** 38.466"
Earth********** 33.073"****************** 32.392"
Mars********** 27.609"****************** 24.686"
Jupiter********** 14.524"****************** 13.042"
Saturn********** 10.831"****************** 9.519"
Uranus********** 7.446"****************** 6.992"
Neptune********** 6.064"***************** 5.929"
( 58.404" + 32.938" )/2 = 45.671" , I still don't know what this average data means.
