Persėjo žvaigždynas


Persėjas (Perseus, Per) – 24-as pagal dydį šiaurinio pusrutulio žvaigždynas Paukščių Take. Lietuvoje matomas rudenį. Žvaigždynas žinomas nuo seniausių laikų (aprašytas dar Ptolemėjaus). Persėjas randamas pratęsus Andromedos trijų žvaigždžių lanką Vežėjo kryptimi (į priešingą pusę nei Pegasas). Ryškiausios žvaigždės sudaro lankelį. Lietuviškas pavadinimas – Kūlėjai ir Spragilas (V. Straižio identifikacija). Ryškiausia žvaigždyno žvaigždė Algolis ryškumą keičia kas keletą dienų.


Nubrėžus liniją per ε Per ir ζ Per surandame Sietyną, o pratęsus lanką iš žvaigždžių γ Per, α Per bei δ Per, pataikome į Kapelą.
