Heraclides Ponticus (Greek: Ἡρακλείδης ὁ Ποντικός Herakleides; c. 390 BC – c. 310 BC)[1] was a Greek philosopher and astronomer who was born in Heraclea Pontica, now Karadeniz Ereğli, Turkey, and migrated to Athens. He is best remembered for proposing that the Earth rotates on its axis, from west to east, once every 24 hours.[2] He is also hailed as the originator of the heliocentric theory; although this is disputed.[3][4]
