Proper name: Shows the star’s common proper name so you can recognize the traditional identity used in literature and star charts.
Other designation: Lists common catalog or Bayer/Flamsteed IDs so you can cross-reference scientific catalogs and observing guides.
Constellation (full name + IAU abbr.): Gives the constellation name and IAU abbreviation so you can quickly place each star on the sky map.
Distance (ly): Provides distance in light-years to one decimal so you understand relative distances between stars at a glance.
Apparent V magnitude: Shows V-band brightness to two decimals so you can assess how bright each star appears from Earth for observing.
