Eridanus is one of the most extensive constellations, however most of its stars are fairly faint and half the constellation extends below -30, which means much of North America and Europe cannot see many of its stars.

On the other hand, if you live in Central America or equivalent latitude you'll be able to enjoy the entire journey.

It's quite an adventure to set out at the river's source, lambda Eridani, next to Rigel (beta Orionis), and to follow its course through the twists and turns, as far as you can until (probably) it disappears over the horizon at some point.

I encourage you to follow each stop along the way. You'll be amazed at how easily you can follow the river's progress, even with the naked eye.

So get ready to set out on that adventure -- click on beta Eridani (upper lefthand corner) to begin your trip down the fabeled Eridanus.
