This was 300 years before Copernicus, who died in 1543 A.D. Planets p.12 says that way back in 275 B.C. Aristarchus of Samos said the heavens revolve around the sun, not the earth, but everybody back then "knew" that was crazy.
Hii ilikuwa miaka 300 kabla ya Kopernika, aliyekufa mwaka 1543 BK Sayari uk. 12 inasema kuwa huko nyuma katika mwaka 275 KK. Aristarko wa Samos alisema mbingu hulizunguka jua, na si dunia, lakini kila mmoja enzi zile "alijua" kuwa jambo hilo lilikuwa uchizi.
