who discovered that the planets orbit the sun?
tycho brahe
nilakantha somayaji (1444–1544), in his aryabhatiyabhasya, a commentary on aryabhata's aryabhatiya, developed a computational system for a partially heliocentric planetary model, in which the planets orbit the sun, which in turn orbits the earth, similar to the tychonic system later proposed by tycho brahe in the late 16th century. in the tantrasangraha (1500), he further revised his planetary system, which was mathematically more accurate at predicting the heliocentric orbits of the interior planets than both the tychonic and copernican models.

the system has five stars and seven brown dwarf/protostars. all the stars orbit the white sun, which is a class a0 giant, 2.5 times bigger than sol and 80 times as bright. the "central planets" are the terrestrial worlds that orbit the white sun. farther out in this system the red sun and georgia share an orbit, along with the worlds orbiting these stars, referred to as "border planets". the fourth star kalidasa and its planets orbit next. after that, the fifth and last star blue sun and its planets orbit. worlds orbiting these last two stars comprise "the rim". planets too far away from the biozones of the main stars are sustained for habitability by a series of protostars. the protostars qin shi huang and lux orbit the white sun. murphy orbits georgia. himinbjørg and heinlein orbit the red sun, penglai orbits kalidasa, and burnham orbits the blue sun.
