[15] In Chinese astronomy, Delta Capricorni is known as 壘壁陣四 (Lěi Bì Zhèn sì), meaning 'The Fourth Star of the Line of Ramparts'.

[23] In 1906 astronomer Vesto Slipher of Lowell Observatory discovered that Delta Capricorni A was a spectroscopic binary.

[24] The orbit was determined in 1921 by Clifford Crump using 69 radial velocity measurements obtained at Yerkes Observatory.

[32] Delta Capricorni A is an Algol-type eclipsing binary star, with an orbital period of 1.022768 days and an inclination close to the line of sight from the Earth.

[2] Delta Capricorni A has an overall stellar classification of A7m III, indicating that it is a giant star that has exhausted the supply of hydrogen at its core.

[34] According to astrology, Delta Capricorni's representation of a flexible tail is reflected in its association with both good and bad fortune alike.

[35] It was one of the fifteen Behenian stars of medieval astrology, associated with chalcedony, marjoram and the kabbalistic symbol .
