- Delta Cephei (δ Cep, δ Cephei) is a quadruple star system located approximately 887 light-years away in the northern constellation of Cepheus, the King. At this distance, the visual magnitude of the star is diminished by 0.23 as a result of extinction caused by gas and dust along the line of sight. It is the prototype of the Cepheid variable stars that undergo periodic changes in luminosity.

The Federal Security Service of the Russian Federation (FSB, ФСБ; Russian: Федеральная служба безопасности Российской Федерации, tr. Federal’naya sluzhba bezopasnosti Rossiyskoy Federatsii, IPA: [fʲɪdʲɪˈralʲnəjə ˈsluʐbə bʲɪzɐˈpasnəstʲɪ rɐˈsʲijskəj fʲɪdʲɪˈratsɨɪ]; ФСБ России) is the principal security agency of Russia and the main successor agency to the Soviet Union’s KGB; its immediate predecessor was the Federal Counterintelligence Service (FSK) which was reorganized into the FSB in 1995. The three major structural successor components of the former KGB that remain administratively independent of the FSB are the Foreign Intelligence Service (SVR), the Federal Protective Service (FSO), and the Main Directorate of Special Programs of the President of the Russian Federation (GUSP).
