"864 / 72 = 12  Precession of Equinox"  "864 / 57.6 = 15  Precession of the Perihelion"   12 + 15 = 27
The symbol on seals of the humped "Kakudmi"  27 Catur-Yugas had passed from the founding of
Dwaraka "Kusasthali" too the Kali-Yuga.

58 x 90 degrees = 5220   5220 / 72
= 72.5
Here both 72 and 72.5 are to high a
ratio for the precsion of Equinox
57.6 x 90 = 5184     5184 / 72 = 72  
this is max below is posible as
5174 / 72 = 71.8611     today's rate
is 71.6
Because 864 is the constant 4320 +
864  or 864 x 5 = 5184
5184 / 57.6 = 15     square root of
5184 =72
179370.02 / 864 = 207.6041
The Sun is not centered in the middle
of the semi-major axis, it is centered
between the center of the Semi-major
axis and the Perihilion. This is the start
of the Kali Yuga the Vernal Equinox
and Fall Equinox the sun is the same
distance..  In the image to the right the
top Perihilion is 0 Mesha.
864 / 9.8216 = 87.969  one orbit of Mercury as 87.969 x 4.152 = 365.247       
SI system based on 86400 seconds for one day
       at the equator the acceleration of the observer is 9.8144
                at Meru the acceleration of the observer is 9.8216
             at the pole the acceleration of the observer is 9.8322

                                                                      
                             
At the Kali both suns are 7 hours
Red line is
today 12
degrees from 0
Mesha
At o Mesha (Aries 1144 - 1244) the
Winter Solstice was closest to the sun,
10,000 years it was oppisite so that
winter had the most distance from the
sun. The last Ice Age Ended 10,000
years ago.
Siddaantas gives Jupiter 364220 and a
yuga 4320000  
4320 / 364.22 = 11.8616
364.22 / 4.15 orbits per earth orbit =
87.7
