| dbo:abstract | HD 34968 is a binary star system in the southern constellation Lepus. The combined apparent visual magnitude of 4.69 is bright enough to be visible to the naked eye. The distance to HD 34968 can be estimated from its annual parallax shift of 8.7 mas, yielding a range of 374 light years. It is moving further away from the Earth with a heliocentric radial velocity of 31 km/s, having come within 118.6 ly some 3,686,000 years ago. The primary member, component A, is a magnitude 4.73 star. Houk and Smith-Moore (1978) gave this object a stellar classification of A0 V, indicating it is an ordinary A-type main-sequence star. Gray and Garrison (1987) classified it as B9.5 III and noted that the spectrum is slightly variable. It is 99.2%±2.6% of the way through its main sequence lifetime, with 3.34 times the mass of the Sun and 2.0 times the Sun's radius. The star is spinning with a projected rotational velocity of 84 km/s. It is radiating 245 times the Sun's luminosity from its photosphere at an effective temperature of 10,046 The fainter secondary, component B, is a magnitude 8.45 star at an angular separation of 4.1″ along a position angle of 279°, as of 2008.

(fr) HD34968 — подвійна зоря. Ця подвійна система має видиму зоряну величину в смузі V приблизно 4,7.Вона розташована на відстані близько 458,7 світлових років від Сонця. (uk) HD 34968 är en dubbelstjärna i den mellersta delen av stjärnbilden Haren. Den har en kombinerad skenbar magnitud av ca 4,69 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 8,7 mas, beräknas den befinna sig på ett avstånd på ca 374 ljusår (ca 115 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 31 km/s.
