Zeta Cancri

Zeta Cancri (ζ Cnc, ζ Cancri) is a star system in the constellation Cancer containing at least four stars. It has the traditional name Tegmine (Tegmen) "the shell (of the crab)". The star system is approximately 83.4 light years from Earth, and has a combined apparent magnitude of +4.67. Since ζ Cancri is near the ecliptic, it can be occulted by the Moon and, very rarely, by planets.

In Chinese, 水位 (Shuǐ Wèi), meaning Water Level, refers to an asterism consisting of ζ Cancri, 6 Canis Minoris, 11 Canis Minoris and 8 Cancri. Consequently, ζ Cancri itself is known as 水位四 (Shuǐ Wèi sì, English: the Fourth Star of Water Level.)
