Main Objectives
Gaia will conduct a census of a billion​​ stars in our Galaxy, monitoring each of its target stars about 70 times over a five-year period. It will precisely chart 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 Solar System, Gaia should also observe hundreds of thousands of asteroids.
