Delta Capricorni (δ Cap / δ Capricorni), also traditionally named Deneb Algedi and or Scheddi, is a quaternary star system approximately 39 light-years away in the constellation of Capricornus (the Sea Goat).The primary star in the system is a white giant star and the combined light of its four members makes it the brightest "single" star within the constellation. the object is a mildly "active late-type star"
[3] This notation indicates that the K-line matches the temperature of an A5 star, the hydrogen spectral type matches an F0 star, and the metallic absorption lines match an F2 star. There are five meteor showers associated with Capricornus: the Alpha Capricornids, the Chi Capricornids, the Sigma Capricornids, the Tau Capricornids, and the Capricorniden-Sagittarids. light.

Fixed star Deneb Algedi, Delta Capricorni, is a 2.8 magnitude binary star system in the Tail of the Sea Goat, Capricornus Constellation.The traditional name Deneb Algedi comes from the Arabic term ذنب الجدي (ðanab al-jady) which means the tail of the goat.
