How can i find the name of a specific star?

Answer 1

Star charts are available on the internet that give the identity of "named" stars. The vast majority are simply identified by an alphanumeric designation established by the IAU.

Answer 2

A star can have MANY different "names."
All the BRIGHTER stars are commonly referred to by any
of the following three designations
1. Common name "Polaris"
2. Bayer name "Alpha Centauri"
3. Flamsteed name "61 Cygni"

Very dim stars visible only in very powerful telescopes won't have common, Bayer, or Flamsteed names and may only
have names given in one or more of dozens of specialty star catalogs:
SAO "SAO 1227"
PPM "PPM 217"
HD "HD 33"
HR "HR 127"
GSC "GSC 123,433"

Some dim stars will be in only one catalog others will be in multiple catalogs and a few will be in practically all of them.

To find the name of a specific star in the sky first identify what constellation it is in then look it up in a star chart either online or at the library.

You can't really see a star much dimmer than magnitude 5.5, so if you are using a computerized star chart change then settings to show only those stars with magnitudes greater than 5.5. This will make ID much easier. If your star is rather bright set the program to display magnitudes greater than 4.0 and you should have it easily.
