Galaxies are grouped by their shape into spiral, elliptical and irregular galaxies. The Milky Way is a spiral galaxy, more precisely a barred spiral: a flat disc of stars, gas and dust with spiral arms winding out from a central bulge crossed by a bar of stars. The Sun lies in one of its arms, the Orion Arm, about 26,000 light years from the centre.
