An inconspicuous summer constellation of Vulpecula is positioned just south of the Northern Cross, Cygnus.
The constellation has been established by Hevelius in 17th century, and is drawing a fox holding a bag of bird.
The constellation's name of "Little Fox" was called "Little fox and Goose" in the beginning.
It's considerably difficult to form the constellation because it has the brightest stars of only 4th magnitude.
But the constellation contains a famous planetary nebula of "Dumb-bell Nebula (M27)" around the central region,
the nebula has made the constellation's name comparatively known. |
