TESS is expected to perform an all - sky survey focused on finding transiting rocky planets around nearby stars, planets that could then be studied in further detail by NASA's James Webb Space Telescope, which would launch no sooner than 2018.
Earth and the other planets of our solar system suffer occasional impacts when comets are disturbed from their orbits around the sun by the gravity of nearby stars and gas clouds.
By the time Webb is operational, Clampin says, another NASA mission, the Transiting Exoplanet Survey Satellite (TESS), slated for launch in 2017, will already be producing a short list of other potentially habitable rocky planets around nearby small stars.

Re 51 Tom P — watched the video; and I agree that the sun does wobble around the center of mass of the solar system; the center of mass itself is not tending to wobble around the sun because conservation of momentum applies to the solar system as a whole (except of course for the forces applied to it by nearby stars, the rest of the galaxy, etc, but those are not varying so fast and so the center of mass should generally be moving along rather smoothly on the same timescale as planetary motions).
