Tau Eridani

Tau Eridani (τ Eri, τ Eridani) is a group of fairly widely scattered stars in the constellation Eridanus.

They form an exception to the general rule that stars that share the same Bayer designation are close together: τ1 is nearly 20° away from τ9 (Pi Orionis is another example of this).

All of them were member of asterism 天苑 (Tiān Yuàn), Celestial Meadows, Hairy Head mansion.[10]
