Question by VS Prasad: Why did ancient Indians designated Moon as a planet?
Precession of earth’s axis: The Vedic seers came up
with the value of 25,870 years. How these ancient
people were able to make these calculations, however is
“as great a mystery as the origin of life itself”.
There are many texts like Khagola-shastra in ancient
India. The original findings of ancient India were:
(1) The calculation of occurrences of eclipses
(2) Determination of Earth’s circumference
(3) Theorizing about the theory of gravitation
(4) Determining that sun was a star and
determination of number of planets.
Aryabhata wrote that 1,582,237,500 rotations of the
Earth equal 57,753,336 lunar orbits. This is an
extremely accurate ratio of a fundamental astronomical
ratio (1,582,237,500/57,753,336 = 27.3964693572), and
is perhaps the oldest astronomical constant calculated
to such accuracy.
It is known to modern science that mass of any
satellite in our solar system is less than a 20th part
of the planet. In case of our moon, it is more than a
10th of the mass of earth. Such a case should be
designated as a ‘twin-planet system’. Such systems were
found around some other stars also. Our moon does not
rotate around the center of the earth. Both of them
rotate around a common geometric center determined by
the momentum of each.

Because they were ignorant. There ideas were false not based on scientific evidence.
