Gould Belt
From Wikipedia, the free encyclopedia
The Gould Belt is a partial ring of stars about 3000 light years across, tilted towards the galactic plane by about 16-20°. It contains many O- and B-type stars. Gould's Belt is suspected to represent the local spiral arm of which the Sun, located approximately 325 light years from the centre, is a member. It is estimated to be 30-50 million years old, however its origin is unknown. It is named after Benjamin Gould, who identified it in 1879. [1] [2] [3]
