Stars In Eridanus

Orbit Unlimited.

A star is named by a Greek letter and a constellation. Thus, Alpha Centauri is the brightest star in Centaurus whereas Epsilon Eridani is the fifth brightest star in Eridanus. But why does Joshua Coffin differentiate Epsilon Eridani from e Eridani? is e not Epsilon (E in Greek)? No. Apparently e is Eta (H in Greek). (They had stopped teaching Greek in the senior classes in school by the time I got there.)

A few years back, a Latin tutor gave us this transliteration:

iota, i;

delta, d;

epsilon, e;

alpha, a -

 

- idea.

 

An important word all the way from Greek through Latin into English.

 

Addendum: No, I got that wrong about Eta. See The Greek Alphabet. I don't know what Coffin was getting at.
