- Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural, and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, whilst its western boundary is defined in various ways. Most definitions include the countries of Belarus, Russia, Ukraine, Moldova and Romania while less restrictive definitions may also include some or all of the Balkans, the Baltic states, the Caucasus and the Visegrád group.
- Acamar (stars.astro.illinois.edu)
ACAMAR (Theta Eridani). Eridanus, the River, the embodiment of the Greek’s “River Ocean,” unlike real rivers has two ends. It now terminates in the brilliant first magnitude star Achernar (Alpha Eridani), the name from an Arabic phrase that means “the end of the river.” But Achernar is too far south to be visible from Greece. The original end of the river was the star we still call Acamar, which derives from the same phrase and means the same thing.
