Eridanus

In Greek mythology, Eridanus ("the river") was considered one of the rivers of Hades by Virgil VI, 659. Herodotus III, 115 associated it with the river Po because the Po was located near the end of the Amber Trail. Amber originated from the tears of the Heliades shed when their brother, Phaeton, died and fell from the sky into the Eridanus.

Eridanus (the river) is the sixth largest of the 88 modern constellations. It was also one of Ptolemy's 48 constellations. At its southern end is the first magnitude star Achernar (α Eri).

Another well-known star in Eridanus is Epsilon Eridani, which has been popular in science fiction because it is relatively close and relatively sun-like. It is now known to have at least one planet (see Extrasolar planet).
