  • 19 Lyrae, som är stjärnans Flamsteed-beteckning är en ensam stjärna i den mellersta delen av stjärnbilden Lyran, som också har variabelbeteckningen V471 Lyr. Den har en genomsnittlig skenbar magnitud på ca 5,93 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 3,5 mas, beräknas den befinna sig på ett avstånd på ca 940 ljusår (ca 289 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet av ca -30 km/s och kan komma så nära solen som 167 ljusår om ca 8,5 miljoner år. (sv)
