This list includes 23 Stars with proper names that start with A, from “Acamar (IAU)” to “Avior (IAU)”. They range from bright navigational stars to faint traditional names preserved by the IAU and historical catalogs.
Stars with proper names that start with A are stars whose accepted names begin with the letter “A”. Many names come from Arabic and Greek traditions, while Acamar illustrates a modern IAU adoption.
Below you’ll find the table with Proper name, Bayer/Flamsteed, Constellation, V magnitude, Distance (ly), and IAU status.
Proper name: The star’s widely used proper name helps you identify traditional and IAU-approved names quickly across catalogs.
Bayer / Flamsteed designation: Shows the star’s classical catalogue label so you can match it with older star charts and literature.
Constellation (full name + abbreviation): Lists the modern constellation and its IAU abbreviation so you can locate the star on maps.
Apparent V magnitude (mag): Gives brightness on the V scale to two decimals, helping you estimate visibility with or without optics.
Distance (ly): Shows the star’s distance in light years to one decimal, giving you a sense of physical scale.
IAU status / notes: Flags IAU-approved names and adds concise notes about historical names or naming conflicts you should know.
