Zet

Its story

Zeta Mensae lives in Mensa, the only constellation named after a feature of the Earth: South Africa's Table Mountain, from where Lacaille charted the southern sky in the eighteenth century. It is a white giant spinning at 200 km/s, fast enough to flatten it into an oblate shape some 26 percent wider at its equator than at its poles. It shines at 414 light-years, almost touching the south celestial pole.
