Solar system science with ESA Euclid
Carry
With current survey design, about 150k SSOs (solar system objects), mainly from the astroid main belt, should be observed by Euclid. These obeys will all have high inclination. There is a potential for discovery of several 10k SSOs, in particular KBOs at high declination. Euclid observations will refine the spectral classification of SSOs by extending the spectral coverage provided by, e.g. Gaia and the LSST to 2 microns. The time-resolved photometry, combined with sparse photometry will contribute to the determination of SSO rotation period, spin orientation, and shape model. The sharp and stable point-spread function of Euclid will also allow to resolve KBO binary systems and detect activity around Centaurs. The depth of Euclid survey, its spectral coverage, and observation cadence has great potential for Solar System research. A dedicated processing for SSOs is being set in place to produce catalogs of astrometry, multicolor and time-resolved photometry, and spectral classification of some 1e5 SSOs, delivered as Legacy Science.
