Pi-1

Its story

Pi-1 Orionis opens the loose scatter of six stars that trace Orion's Shield, the curved arc the Hunter raises against the charge of the Bull. It is a young white star, only a hundred million years old, spinning on itself at 120 kilometres per second. At 116 light-years, it carries nearly twice the Sun's mass and shines with seventeen solar luminosities, marking the leading edge of Orion's celestial bow.
