HD 92209 eller HR 4170, är en möjlig dubbelstjärna^[11] i norra delen av stjärnbilden Kameleonten. Den har en skenbar magnitud av ca 6,29^[2] och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 3 på ca 5,4 mas,^[1] beräknas den befinna sig på ett avstånd på ca 600 ljusår (ca 184 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 18 km/s.^[5]

Egenskaper

HD 92209 är en orange till röd jättestjärna av spektralklass K2 III.^[4] Den har en massa som är ca 1,2^[7] solmassa, en radie som är ca 14,4^[8] solradier och har ca 81 gånger solens utstrålning av energi^[11] från dess fotosfär vid en effektiv temperatur av ca 4 500 K.^[9] Stjärnan är möjligen en spektroskopisk dubbelstjärna.^[11]
