Upsilon 2 Eridani · Eridanus
What is Theemin
Theemin flows among the long curves of Eridanus, the celestial river that the ancients identified with the Nile or the Po, depending on the culture. It is a yellow G-type star, similar to our Sun but more evolved, about 214 light-years away. The light crossing the river tonight set out around 1812, the year Napoleon retreated from Moscow under the snow.
