Den har en skenbar magnitud av ca 4,59 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 19,2 mas, beräknas den befinna sig på ett avstånd på ca 170 ljusår (ca 52 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 10 km/s.liocentrisk radialhastighet på ca 10 km/s.
, HD 23319 (h Eridani) is an orange-hued sta … HD 23319 (h Eridani) is an orange-hued star in the constellation Eridanus. It has an apparent visual magnitude of 4.59, which is sufficiently bright to make it visible to the naked eye. The distance to HD 23319 can be estimated from its annual parallax shift of 19.2 mas, which yields a range of about 170 light years. It is moving further away from the Earth with a heliocentric radial velocity of +9.9 km/s. This is an aging giant star with a stellar classification of K1.5 IIIb CN0.5, where the suffix notation indicates the spectrum shows a mild overabundance of the cyano radical. It is a red clump giant, indicating it is on the horizontal branch and is generating energy through helium fusion at its core. The star has 1.2 times the mass of the Sun and, at the age of 4.6 billion years, has expanded to 11 times the Sun's radius. It is radiating 63 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,581 K.re at an effective temperature of 4,581 K.
