[Advaita-l] Velocity of the planets as told by Aryabhata

[P R]

*Velocity of the planets in a yuga from Aryabhatiya*



The velocity of the planets, that is the number of revolutions in a yuga (
432 * 10^ 4) are mentioned in the aryabhatiya gitika shloka 3 and 4

The planets are arranged in the increasing order if their velocity, along
with explanations

The rule *अङ्कानाम् वामतोगतिः* is used invariably here


1.  Saturn ( Shani) दुङ्विध्व

ढ् (उ) + ङ् (इ) + व् (इ) + घ् (अ) +व् (अ)

14( 10^4) + 5 (10^2) + 6(10^3) +4(1) +6(10)

= 1,46,564

2. Guru ( Jupiter) ख्इच्युभ
ख(इ) + र् (इ) + च् (उ) + य्(उ) + भ् (अ)

2(10^2)+ 4(10^3) + 6 (10^4) + 3(10^ 5) +24(1)

= 3,64, 224

3 Mangala ( Mars) भद्लिझुनुखृ

भ(उ) +द्(इ) +ल् (इ) + झ् (उ) + न् (उ) + ख(ऋ)

24(10^0) + 18(10^2) + 5(10^3)+ 9(10^4)+20(10^4) +2(10^6)
= 22,96,824

4. Ravi (sun) ख्युघृ

 ख् (उ) +य् (उ)+घ्(ऋ)
2(10^4) + 3(10^3)+ 4(10^6)

= 4320000

5. Soma (moon) चयगियिङुशुछृलृ

च्(अ) +य्(अ) +ग्(इ) +य्(इ) +ङ्(उ) + श्(उ) + छ् (ऋ) +ल् (ऋ)

6(1)+3(10)+3(10^2)+3(10^3)+5(10^4)+7(10^5)+7(10^6)+5(10^7). *अङ्कानाम्
वामतोगतिः* rule is used here
