HD 1606 är en ensam stjärna^[13] belägen i den mellersta delen av stjärnbilden Andromeda. Den har en skenbar magnitud av ca 5,87^[2] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 5,6^[1] mas, beräknas den befinna sig på ett avstånd på ca 580 ljusår (ca 179 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 4 km/s.^[6]

Egenskaper

HD 1606 är en blå till vit stjärna i huvudserien av spektralklass B7 V.^[3] Den har en massa som är ca 3,8^[8] solmassor, en radie som är ca 2,9^[9] solradier och har ca 245 gånger solens utstrålning av energi^[8] från dess fotosfär vid en genomsnittlig effektiv temperatur av ca 13 200 K.^[10]

Även om HD 1606 misstänks vara en variabel stjärna har ingen variation i dess magnitud kunnat slutgiltigt observeras.^[14]
