Eridanus
Eridanus is the Celestial River. It's the second longest constellation in the sky. If you live in the Northern Hemisphere, you will only see the top half of the constellation.
The brightest star in Eridanus is at the very end. It's called Achernar. Can you find it on the image?
The best time to find Eridanus is from November through February. First find the bright star Rigel in Orion. See if you can find all the stars in the sky!
