Which constellation, Orion, Sirius, Pegasus, Andromeda or Cassiopeia is the odd one out and why?

I thought Sirius was a star. But I also thought Pegasus was a mythical winged horse, Andromeda was a strain, and Cassiopeia was a disease or a polynesian foodstuff. So I'm gonna say Orion.Which constellation, Orion, Sirius, Pegasus, Andromeda or Cassiopeia is the odd one out and why?andromeda-it is not a constellation/star. the others are stars which make a constellationWhich constellation, Orion, Sirius, Pegasus, Andromeda or Cassiopeia is the odd one out and why?Sirius, which is the chief star of the constellation Canis Major.



In Greek mythology the others are all figures from Greek mythology who were placed amongst the stars.



Sirios, on the other hand was born a star, she was a daughter of the Titan Atlas, and a sister of the seven stars of the Pleiades and the five Hyades. Her proper name was Maera.Which constellation, Orion, Sirius, Pegasus, Andromeda or Cassiopeia is the odd one out and why?Sirius is a star, not a constellationWhich constellation, Orion, Sirius, Pegasus, Andromeda or Cassiopeia is the odd one out and why?
