Notes. For the whole celestial sphere, we report the current number of known SSOs (now, at the time of the writing on 2017 June 28), the expected number of observable objects (S) at the limiting apparent magnitude of Euclid (VAB< 24.5), and the solar elongation (Ψ = 91.0 ± 1.5°). Using the fraction of known SSOs within the area of the Euclid Wide survey (fW) and calibration frames (fC), we estimate the total number of discoveries (E,d) and observations (E,o) by Euclid. The absolute magnitude corresponding to a probability of 100%, 50%, and 1% that SSOs will be within the detection envelop of Euclid are also reported.
