Eridanus Constellation

Eridanus (Pronounciation:Iri-dan-us, Abbrev:Eri, Latin:Eridani) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Eridanus takes up 1137.919 sq. degrees of the night sky which equates to 2.76% of the night sky. The constellation gets its name as it name means River Eridanus . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

Eridanus is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere. The brightest star in Eridanus is Achernar. There are 11 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Legend of the Constellation

Eridanus, the river was where Phaethon fell into when he was knocked out of his chariot basket. Phaethon had taken his father Helios` chariot and rode it across the skies both too high and too lower. As it was scaring the people below, Zeus threw fire bolts at the chariot to stop him. The chariot stopped but Phaethon fell out and into the river.

Meteor Showers

There are 14 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

List of Named Stars in Eridanus without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
