The name Cexing was proposed for Kappa Cas in 2025. After reviewing the literature and deliberation, WGSN adopted for the name for Kappa Cas for the Catalog of Star Names on 12 November 2025.

Cexing is a distant blue supergiant at a distance of about 1000 parsecs. The star served a spectral standard star of type B1Ia (Morgan, Abt, Tapscott 1978, "Revised MK Spectral Atlas for Stars Earlier than the Sun"). The star is a bright example of an Alpha Cygni-type variable star, as a hot supergiant showing variability at the ~0.07 mag level with a periodicity of 2.6 days. The star is a "runaway star" which is ploughing through its neighboring gas and dust, illuminating a bow shock nebula detected in the infrared by the Spitzer Space Telescope.
