I've been observing the stars and I have found some lists on internet that sort them by its apparent magnitude (m), so you end up with lists of brightest-stars like this one: https://www.star-facts.com/brightest-stars/

The problem is that I would like to sort them beyond 300 (The maximum amount that I've found on internet sites), but I don't know where can I find (or if it even exist) such a list. The star number 300 (Xi Serpentis) has a apparent magnitude of 3.54, but there are some other stars like: Atlas (m = 3.62) that have apparent magnitudes bigger of 3.54. I would like to know what position stars like these they occupy

The Yale Bright Star Catalogue lists stars brighter than about magnitude 6.5.

It is available as a compressed text file documented in the readme file

I've also made a google sheets version sorted by magnitude

There is lots of information here, the visual magnitude is in the column which begins 6.70\6.29\4.61

The entry for Atlas is

1178 27    TauBD+23  557  23850 76228 142    2786   1345    034312.8+234452034909.7+240312167.01-23.23 3.63  -0.09 -0.36 -0.05   B8III              +0.018-0.047 -.026+009SB1O  212  1.5   0.0 A   3*

Showing that it has a visual magnitude of 3.63

  • $\begingroup$ Just out of curiosity, how many stars were in that catalogue at the time of this answer (since the question is specifically looking for more than 300 stars). $\endgroup$

  • $\begingroup$ Thanks, but how do I make sense of its columns? The brightest star is Sirius in Canis Major and I don't see any information that resembles that. What are the meaning of the columns? $\endgroup$

    $\begingroup$ Yes, Excel can import text files, the structure of the BSC is based on fixed width columns So the Catalogue number is the first four characters, the "name" is characters 5-14, the magnitude is in characters 103-107 and is a signed floating point value with optional sign and two decimal places. $\endgroup$

It's serious overkill, but https://www.usno.navy.mil/USNO/astrometry/information/catalog-info lists many catalogs and their current recommended/usability status.

Unfortunately, it's not 100% complete as it doesn't list the Yale Bright Star Catalog or even GAIA2 (https://gea.esac.esa.int/archive/) which contains over one billion stars.
