29 Persei, som är stjärnans Flamsteed-beteckning, är en ensam stjärna^[14] belägen i den norra delen av stjärnbilden, Perseus. Den har en skenbar magnitud på ca 5,16^[3] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 5,1^[1] mas, beräknas den befinna sig på ett avstånd på ca 640 ljusår (ca 200 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet av ca –1,5 km/s.^[7] Stjärnan ingår i stjärnhopen Alfa Persei.^[15]^[16]

Egenskaper[redigera | redigera wikitext]

29 Persei är blå till vit stjärna i huvudserien av spektralklass B3 V.^[4] Den har en massa som är ca 7^[9] solmassor, en radie som är ca 4^[10] solradier och utsänder ca 960^[8] gånger mera energi än solen från dess fotosfär vid en effektiv temperatur på ca 16 100 K.^[8]
