Notes. The gravitational parameters of the 16 main-belt asteroids are extracted from the header of the JPL ephemerides DE441 (https://ssd.jpl.nasa.gov/ftp/eph/planets/ascii/de441/). The gravitational parameter of Pluto is taken from Brozović et al. (2015). The values are reported in the units of the gravitational parameter of the Sun, corresponding to GM⊙ = 1.32712440040944 × 1011 km3 s−2.
