Škorpija (sazvežđe)
Škorpija (lat. Scorpius) je jedno od sazvežđa zodijaka, sa znakom 
, a pozicionirano je između Vage na zapadu i Strelca na istoku. Velika je konstelacija na južnoj polulopti, blizu središta Mlečnog puta.[1]

Zvezde uredi
Sazvežđe Škorpija sadrži mnoge sjajne zvezde:
- Antares (α Škorpije), crveni div magnitude +1,0, udaljen 650 svetlosnih godina i 11,000 puta sjajniji od Sunca
- Graffias (β1 Škorpije), dvostruka zvezda sa komponentama sjaja +2,6 i +4,9 magnituda, udaljena 530 svetlosnih godina
- Duschubba (δ Škorpije), magnitude +2,3, udaljena 400 svetlosnih godina
- Sargas (θ Škorpije), treća zvezda po sjaju u Škorpiji, udaljena 270 svetlosnih godina i magnitude +1,9
- Shaula (λ Škorpije), druga zvezda po sjaju, ima magnitudu +1,6. Šaula je plavi div udaljen oko 700 svetlosnih godina.
Ostale značajnije zvezde su ν Škorpije, ξ Škorpije, π Škorpije, σ Škorpije, τ Škorpije i υ Škorpije.
Značajni objekti uredi
Zbog blizine središta Mlečnog puta, sazvežđe je bogato galaktičkim objektima. Posebno se ističu zbijena zvezdana jata M6 i M7, kao i rasejana zvezdana jata M4, pored Antaresa i M80. Na južnom kraju sazvežđa, pored zvezde ζ² Škorpiona, nalazi se otvoreni skup NGC 6231.
Mitologija uredi
Škorpija, od svih sazvežđa, najviše podseća na životinju u svom nazivu. Prema grčkoj mitologiji, sazvežđe odgovara škorpiji koje je poslala boginja Hera da ubije lovca Oriona. Iako se sazvežđa Škorpija i Orion nalaze u istom mitu, oni su na nebu gotovo na nasuprotnim delovima nebeske sfere. Govori se da su ih bogovi tako smestili radi izbegavanja njihovog međusobnog kontakta.
