It takes the Solar System about 225–250 million years to complete one orbit of the galaxy (a galactic year), so it is thought to have completed 20–25 orbits during the lifetime of the Sun and 1/1250th of a revolution since the origin of humans. The orbital speed of the Solar System about the center of the Galaxy is approximately 220 km/s. At this speed, it takes around 1400 years for the Solar System to travel a distance of 1 light-year.
The Milky Way and the Andromeda Galaxy are a binary system of giant spiral galaxies.The Milky Way is orbited by two smaller galaxies and a number of dwarf galaxies. In January 2006, observation of stars rising close to perpendicular to the plane of the spiral arms of the Galaxy have led to the proposition that a Dwarf Galaxy may be currently merging with the Milky Way.
Our Milky Way Galaxy is only one of billions of Galaxies in the observable Universe.
Since 1976, the Winter Solstice Sunrise has been occuring within orb of conjunction to Galactic Centre. The Winter Solstice of 2012 marks the closest accuracy that this conjunction will reach. These 30+ years have seen an unprecedented acceleration of transformation and evolution. Collectively we have moved from an industrial culture to an information culture. This specific alignment to Galactic Centre only occurs every 26,000 years in relation to the Procession of the Equinoxs'. The symbol below is the Mayan 'Hunab Ku'. This symbol represents Galactic Centre, or, 'The Black Sun'. The Mayan Long Count ends at the Winter Solstice 2012.
