Gaia’s first asteroid survey

Animated view of 14 099 asteroids in our Solar System, as viewed by ESA’s Gaia satellite using information from the mission’s second data release. The orbits of the 200 brightest asteroids are also shown, as determined using Gaia data.

In future data releases, Gaia will also provide asteroid spectra and enable a complete characterisation of the asteroid belt. The combination of dynamical and physical information that is being collected by Gaia provides an unprecedented opportunity to improve our understanding of the origin and the evolution of the Solar System.

  1. So is that first glance, the greenish orbits, at about 0:15, the asteroid belt? And the other highlighted orbits, whitish, are Jupiter and then the inner planets? Just checking. I tried to find a description or scale here in the YouTube page, but I do not see one. I love this video!
