The Myth of Eridanus

This constellation is related to the Greek mythology. The constellation is related to Phaëton, who was the son of Helios, the sun god and Clymene, the Oceanid. Phaëton kept pleading for his father’s permission as he wanted to drive his father Helios’s chariot across the sky. Helios agreed to it, but as there was the track where wheel marks were present, he advised Phaëton to follow those tracks. After Phaëton mounted the chariot, the horses sensed driver as being lightweight, so the horses flew upwards and left the familiar track behind. As Phaëton was inexperienced, he could not keep the horses in control and so the reins slipped. And then the chariot fell very close to Earth, due to which lands caught fire, both on Heaven and Earth.
