Achird

Etymology and History
The proper name Achird was apparently first applied to Eta Cassiopeiae in the Skalnate Pleso Atlas of the Heavens published in Slovacia in 1950, but is not known prior to that.[1] Even Allen (1899) gives no historical name for the star. The origin is unknown; perhaps it refers to the girdle of the queen Cassiopeia from Greek mythology.

Located just 19 light years away, most of us even remember what we did when the light of this star left its surface. It is a Sun-like star in a binary system, so humans there would see two "suns" in their sky.
