Who named the stars first?
Johann Bayer was the first to use Greek letters for star names — and four centuries later, we use them still. Here is the constellation Taurus from Bayer’s Uranometria atlas of 1603. At least beginners aren’t alone in their confusion of star names.
How did Johann Bayer name stars in constellations?
Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star’s parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form.
