The retrograde motion of planets is a unique feature of our Bhratian Astronomy, Astrology and
Almanacs. These texts describe that Mercury, Venus, Mars, Jupiter and the Saturn have retrograde motion, an apparent backward motion of these planets with respect to the fixed stars of the sky, on observed from the Earth. If analysed in depth, this retrograde motion of these planets, confirm that our Bhratian Astronomy is correctly based on Heliocentric concept only.

Heliocentric theory, but with perfect circular model was said to have been advanced first, by Nicholas Copernicus (1473 – 1543 A.D.) of Europe. Prior to that, in Europe, Claudius Ptolemy’s (~85 -165 A.D.) perfect circular model of Geocentric theory was followed. However, the ancient texts of our Nation like Veda and the astronomical texts clearly revealed not only the Heliocentric theory, but also the elliptical pathway of the planets with their calculations, much advanced than that of Nicholas Copernicus. If the astronomical facts scattered in these texts, are analyzed perfectly they will show that the Bhratian astronomy is based on Heliocentric theory only. Even the Navagraha temple construction in our Nation itself shows the Sun’s centre position, encircled by the other Graha (planets, satellite and nodes).
Value of π is a very essential and fundamental thing, in the calculations of area and
circumference of circles. It was first calculated in our Nation, Bharat and from here only, it spread to the rest of the world. We can show the direct evidences found scattered in the ancient texts our Nation and also the evidences showing its applications in the day-to- day life by our ancestors.
The various narrations and accounts pertaining to King Vikramaditya of Ujjain, found in the ancient texts of our Nation and the historical notes and writings of the foreign scholars and historians were analysed properly and thoroughly.

He started his Era in 57 B.C.E., when he conquered Nepal.
