ESA - Space Science - Gaia overview
Topic: Space 8:57 am EDT, Aug 10, 2007

Gaia is a mission that will conduct a census of one thousand million stars in our Galaxy. It will monitor each of its target stars about 70 times over a five-year period, precisely charting their positions, distances, movements, and changes in brightness. It is expected to discover hundreds of thousands of new celestial objects, such as extra-solar planets and failed stars called brown dwarfs. Within our own Solar System, Gaia should also identify tens of thousands of asteroids.
