ι Persei, Latinized as Iota Persei, is a single star in the northern constellation Perseus. This object is visible to the naked eye as a faint, yellow-white hued point of light with an apparent visual magnitude of 4.1. It is located 34.5 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +49 km/s. Iota Persei has a relatively high proper motion across the sky.
This is a late F- or early G-type main-sequence star with a stellar classification of around G0V. It is about 3–4 billion years old and is spinning slowly with a projected rotational velocity of 4 km/s. The star has 1.1 times the mass of the Sun and 1.4 times the Sun's radius. It is radiating more than double the luminosity of the Sun from its photosphere at an effective temperature of 5,921 K.
There is a 12.4-magnitude line-of-sight companion star that is not believed to be gravitationally associated with Iota Persei. This object is located at an angular separation of {{Val|154.4|ul=arcsecond}} from the primary along a position angle of 125°, as of 2014.
Naming
In Chinese, {{lang|zh|大陵}} ({{lang|zh-Latn|Dà Líng}}), meaning Mausoleum, refers to an asterism consisting of ι Persei, 9 Persei, τ Persei, κ Persei, β Persei, ρ Persei, 16 Persei and 12 Persei. Consequently, the Chinese name for ι Persei itself is {{lang|zh|大陵三}} ({{lang|zh-Latn|Dà Líng sān}}, {{langx|en|the Third Star of Mausoleum}}).{{in lang|zh}} [http://aeea.nmns.edu.tw/2006/0607/ap060711.html AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 7 月 11 日] {{Webarchive|url=https://web.archive.org/web/20120204114123/http://aeea.nmns.edu.tw/2006/0607/ap060711.html |date=2012-02-04 }}
