Will it has a dust ring around the Earth?

Will it has a dust ring around the Earth?

The Gaia spacecraft is ready to begin its observations in orbit around the country Lagrange point L2, despite some unforeseen inconveniences which resulted in a delay of a few months. Intended for galactic archeology, she maybe we already revealed a secret history of the solar system. Hit by a number of higher than expected micrometeorites, Gaia could be plunged into a dust ring that surrounds the Earth.

Launched December 19, 2013 by a rocket Soyuz from Kourou in French Guiana, Gaia began his journey to the Lagrange point  L2. With this instrument mainly dedicated to astrometry, a wide variety of results are expected. It can be used to conduct new tests of metric theories of gravitation , as that of general relativity by studying the deflection of light by the gravitational field of the Sun and planets in the Solar System .  can also detect secular variations in the gravitational constant .
