221 Eos
221 Eos /ˈiːɒs/ is a large main-belt asteroid that was discovered by Johann Palisa on January 18, 1882, in Vienna. In 1884, it was named after Eos, the Greek goddess of dawn, to honour the opening of a new observatory that was hoped to bring about a new dawn for Viennese astronomy. Based upon its spectral characteristics, this object is classified as a K-type asteroid. The orbital properties show it to be a member of the extensive Eos asteroid family, which is named after it.
