It is visible to the naked eye as a faint, white-hued point of light with an apparent visual magnitude of 4.29.[2] This object is located approximately 422\u00a0light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +6\u00a0km\/s.[4]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4  \u03bb Persei in optical lightThis object has a stellar classification of A0IVn,[3] matching an A-type subgiant star with “nebulous” lines due to rapid rotation. It is spinning with a projected rotational velocity of 196\u00a0km\/s,[8] which is giving the star an equatorial bulge that is an estimated 16% larger than the polar radius.[11] Unusually for a star of this type, spectra show weak emission features among the Hydrogen lines, which may be due to plage regions on the surface caused by an implied magnetic field.[12] The star is 345[9]\u00a0million years old and is radiating 348[5] times the luminosity of the Sun from its photosphere at an effective temperature of 10,585\u00a0K.[7]In Chinese astronomy, Lambda Persei is called \u7a4d\u6c34, Pinyin: J\u012bshu\u01d0, meaning Stored Water, because this star is marking itself and stand alone in Stored Water asterism, Stomach mansion (see\u00a0: Chinese constellation).[13]References[edit]^ a b c d e f Van Leeuwen, F.
