Alpha Equulei (α Equulei, abbreviated Alpha Equ, α Equ), officially named Kitalpha /kɪˈtælfə/,[5][6] is a star in the constellation of Equuleus.

[6] In Chinese, 虚宿 (Xū Sù), meaning Emptiness, is an asterism consisting of Alpha Equulei and Beta Aquarii.

[8] Consequently, the Chinese name for Alpha Equulei itself is 虛宿二 (Xū Sù èr, English: the Second Star of Emptiness).

[9] The overall appearance of α Equulei is a G-type giant[10] with an apparent magnitude of +3.92, but it is a spectroscopic binary consisting of two individual stars.

The primary star is a G7 giant about fifty times more luminous than the Sun.
