Monoceros



Abbreviation: Mon
Genitive: Monocerotis
Right Ascension: 7.15 hours
Declination: -5.74 degrees
  Monoceros, the Unicorn, is the almost invisible unicorn. I don't know of any direct mythologies attached to this constellation. It was 'officially' invented in 1690 as Monoceros. Even though Monoceros is devoid of any legends attached to it, it does boast of having the two most massive stars, yet, discovered. The two blue-giants are estimated to be some 55 times the size of the sun, and revolve around each other. Together they are known as Plaskett's Star, the reference I have for them, indicates that they are located at the head of the unicorn.

Monoceros is a modern constellation, generally supposed to have been charted by Bartchius as Unicornus; but Olbers and Ideler indicate the constellation is actually much older, with it appering in works as early at 1564, and Scaliger is reported to have found it on an ancient Persian sphere.
