Yajnavalkya (c. 9th–8th century BC) recognized that the Earth is spherical and believed that the Sun was "the centre of the spheres" as described in the Vedas at the time." "He recognized that the Sun was much larger than the Earth, which would have influenced this early heliocentric concept." Source: http://en.wikipedia.org/wiki/Heliocentrism
