Delphinus 10 arcseconds from the primary. Struve 2725, called the "Ghost Double", is a pair that appears similar but dimmer. Its components of magnitudes 7.6 and 8.4 are separated by 6 arcseconds and are 15 arcminutes from Gamma Delphini itself. Delta Delphini is a type A7 IIIp star of magnitude 4.43. Epsilon Delphini, Deneb Dulfim (lit. "tail [of the] Dolphin"), or Aldulfin, is a star of stellar class B6 III and magnitude 4, at 330 ly. In Delphinus, in extremes of distance, Gliese 795 is the closest known star at 54.95 ly and rapidly moves east over a period of centuries
Delphinus bounds of the constellation since 1992. HR Delphini was a nova that brightened to magnitude 3.5 in December 1967. A nova was discovered by amateur astronomer Koichi Itagaki, Nova Delphini 2013. Giants within our galaxy in Delphinus aside from Delta, Gamma and Epsilon include: Its rich Milky Way star field means many modestly deep-sky objects. NGC 6891 is a planetary nebula of magnitude 10.5; another is NGC 6905 or the Blue Flash nebula. NGC 6934 is a globular cluster of magnitude 9.75. At a distance of about 185,000 light-years, the globular cluster NGC 7006 is at the outer reaches of
