Delta1 Lyrae, its name Latinized from δ1 Lyrae, is a binary star system in the northern constellation of Lyra. It is dimly visible to the naked eye at night with a combined apparent visual magnitude of 5.56. The system is located at a distance of approximately 1,160 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −26 km/s. O. J. Eggen originally included this as a candidate member of the proposed Delta Lyrae cluster.

  • Delta¹ de la Lira (δ¹ Lyrae) és un sistema estel·lar binari a la constel·lació de la Lira, a uns 1.100 anys llum de distància de la Terra. Les dues estrelles completen una òrbita l’una sobre l’altra aproximadament un cop cada 88 dies. Són binàries espectroscòpiques, és a dir, la separació entre ambdues és molt petita i la seva velocitat orbital és molt elevada. El membre principal, el component A, és una estrella de la seqüència principal blanca blavosa del tipus espectral B2.5V. (ca)
  • Delta1 Lyrae (ζ1 Lyrae, förkortat Delta1 Lyr, ζ1 Lyr) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Lyran. Den har en skenbar magnitud på 5,56 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 3,3 mas, beräknas den befinna sig på ett avstånd av ca 990 ljusår (300 parsek) från solen. (sv)
  • Delta1 Lyrae (11 Lyrae) é uma estrela na direção da constelação de Lyra. Possui uma ascensão reta de 18h 53m 43.56s e uma declinação de +36° 58′ 18.2″. Sua magnitude aparente é igual a 5.58. Considerando sua distância de 1079 anos-luz em relação à Terra, sua magnitude absoluta é igual a −2.02. Pertence à classe espectral B2.5V. (pt)
  • 天琴座δ,又名BD+36 3307,HD 175426、SAO 67537、HR 7131,是天琴座的一颗恒星,视星等为5.58,位于銀經66.93,銀緯15.49,其B1900.0坐标为赤經18h 50m 13.9s,赤緯+36° 15.49′ 48″。这对双星是一个非常奇异的天体,主星是5.6等的蓝白色矮星,质量有太阳的8-10倍之大,9.8等的伴星质量小得多,但是已经进入红巨星阶段。由于质量偏低,伴星光度比一般红巨星要小一些,大约是太阳的10倍亮。这对双星类似于大陵五双星,质量小的伴星演化快,而大的主星还是主序星,极有可能是激烈的质量交流所致。 (zh)
