Eri - Eridanus the River

Taurus the Bull is easily spotted. Its head is the Hyades, a V-shaped cluster of stars. His horns point outward from the V. Aldebaran is the red eye of the Bull as he charges down upon us.

A tiny, faint constellation, located south of Orion, barely visible from 35 degrees north latitude in December and January.

South of Aries and Pisces, one of the largest constellations. Trace to the second-magnitude star Beta-Ceti (Diphda, near the flukes) by following a line southward from Alpheratz (the corner of Pegasus and Andromeda) through gamma-Pegasi, across Pisces and Cetus.

The River Eridanus flows northward (like the Nile) from the bright star Achernar (Arabic for "End of the River") to Kursa (beta-Eridani) near Rigel in Orion. Eridanus is the longest (not largest) constellation, spanning over 50 degrees of declination, and its many faint stars glitter like reflecting light off the surface of its waves.

A small constellation of faint stars nestled within a bend of the river (Eridanus), low in the south.

Hydrus has only three stars above the fourth magnitude.Hydrus is the Little Snake, not to be confused with Hydra, the big one.

Three stars in a row make up Orion’s belt, within a rectangle of four bright stars representing his shoulders and feet. At sunset in the autumn, Orion’s belt appears to rise straight up on the horizon. The sword hanging from his belt includes M42, the beautiful Orion nebula.

Since Orion’s belt of three bright stars lies upon the celestial equator, Orion is visible from every inhabited part of the globe.

Partially visible during early October low in the south from 35 degrees north latitude.
