Perseuse tähtkuju öötaevas




Perseus Medusa peaga


Perseus (ladina Perseus, lühend Per) on põhjataeva tähtkuju, mis jääb suures osas Linnuteele ja on nime saanud vanakreeka mütoloogilise kangelase Perseuse järgi. Perseus oli Zeusi ja Danae poeg, kes tappis Medusa ning päästis Andromeda merekoletise Ketose käest.


Perseus on üks 48 Ptolemaiose loetletud tähtkujust. See katab tähistaevast 615 ruutkraadi ja on pindalalt 24. tähtkuju.[1] Eestis on see vaadeldav aastaringselt.[2]


Heledaim täht on α Persei ehk Mirfak, mille näiv suurus on 1,79.[3] β Persei ehk Algol on tuntud oma muutliku heleduse poolest, mis muutub 3,5 ja 2,3 tähesuuruse vahel 2,867 päevase intervalliga.




NGC869 ja NGC884


NGC 869 ja 884 (h ja χ Persei) moodustavad palja silmaga nähtava kaksiktäheparve. Eestis tunti seda Kadri Sõela nime all.[4]


Eesti rahvapärimuse järgi olid Perseuse tähtkujus Küünlapäevatähed, mis moodustasid Ridamuse ühe haru.
