The Astronomical Units of Time Measurement
We find Yuga cylces mentioned not only in astronomical works, but also in
mythological works in India.
Kali Yuga began on the midnight of 17th Feb 3102 BCE and the duration of
this Kali Yuga is said to be 4.32 K solar years. Dwapara is 2*Kali Yuga
years. Treta is 3*K Y and Krita Yuga is 4*K Y.
Krita Treta Dwaparascha Kalischaiva Chaturyugam
Divya Dwadasabhir varshai savadhanam niroopitham
Thus an Equinoctial Cycle, Mahayuga is equal to 4+3+2+1 = 10 KYs.
E C = 10 KYs.
A Greater Equinoctial Cycle ( Manvantara ) = 71 Equinoctial Cycles
There are cusps happening in between Manvantaras, each equal to a Krita Yuga
in duration. A Krita is equal to 4 KYs or 2/5 of a Maha Yuga. Since there
will 15 such cusps happening amongst the Fourteen Manvantaras, they are
equal to 15*2/5 = 6 Mahayugas.
Hence 14*71+6 = 1000 Mahayugas = 4.32 Billion Years

This is one Cosmological Cycle, called Brahma Kalpa.

From one second, it can be logarithmically shown, upto 10^22 seconds.
From 10^0 it goes upto 10^22 seconds. One day of Brahma is 4.32 billion
years and 100 years of Brahma therefore is 311.04 trillion years.
One Asu is 4 seconds, one Vinadi is 24 seconds and one Nadi is 24 minutes.
60 such Nadis make up one day. This is the Sexagesimal division of a day
into 60 Nadis ! In Astronomy, one degree is sixty minutes and one minute is
sixty seconds. Hence sexagesimal division is justified ! 365.25 such days
constitute a year and Hindu calculation goes upto 311.04 trillion years !
Mean and true planetary longitudes in the Zodiac is computed by Nine Orbital
Elements, in Indian Astronomy.
Mean longitude of Planet, Graha Madhyama , M
Daily Motion of the Mean Longitude, Madhyama Dina Gathi, Md
Aphelion, Mandoccha, Ap
Daily Motion of Aphelion, Mandoccha Dina Gathi, Apd
Ascending Node, Patha, N
Daily Motion of Ascending Node, Patha Dina Gathi, Nd
Heliocentric Distance, Manda Karna, radius vector, mndk
Maximum Latitude, L, Parama Vikshepa
Eccentricity, Chyuthi,e
In Western Astronomy, we have six orbital elements
Mean Anomaly, m
Argument of Perihelion, w
Eccentricity, e
Ascending Node, N
Inclination, i, inclinent of orbit
Semi Major Axis, a
With the Nine Orbital Elements, true geocentric longitude of the planet is
computed, using multi step algorithms.
There is geometrical equivalence between both the Epicycle and the Eccentric
Models.
The radius of the Epicycle, r = e, the distance of the Equant from the
Observer.
