The Quest of Astronomers to Find the Distance of Sun

Archimedes, a Greek mathematician and philosopher, estimated the distance of Sun from Earth as 10000 times the radius of Earth

  • Hipparchus gave an estimate of 490 times Earth’s radius
  • Ptolemy considered the distance to be 1210 times Earth-sun distance
  • Johannes Kepler realized these distances were significantly low
  • Kepler’s law of Planetary Motion allowed astronomers to calculate the relative distance of the planets

Hanuman Chalisa

Distance between Sun and Earth = 12000 x 1000 yojanas = 96 million miles = 153.6 million kms

  • Assumptions
  • assumed yuga to mean the number 12000 based on the time calculation system of Vedic period
  • approximated 1 yojana = 8 miles based on what Srila Prabhupada has mentioned in his purports
  • However, there is still disagreement among scholars as to whether it is 5 miles or 8 miles

Srila Prabhupada writes in one of his purports:

Modern scientific calculations are subject to one change after another, and therefore they are uncertain. We have to accept the calculations of the Vedic literature. These Vedic calculations are steady.

  • Whether or not modern ones are better may remain a mystery for others, but as far as we are concerned, we accept the VedIC calculations to be correct.

The distance between Sun and Earth is yuga-sahasra-yojana = 12000 x 1000 yojanas

Yojana is a Vedic measure of distance and approximately equals to 8 miles (according to the 14th century scholar Parameshvara, the originator of drgganita system).
