Notes. (a)Orbital elements from JPL Small-Boby Database Browser web page (https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=2882MS4). (b)Physical properties obtained by Vilenius et al. (2012): area-equivalent diameter (D) and geometric albedo at V-band (pV); HV: average absolute magnitude at V-band; Stansberry et al. (2008) obtained D = 726.05 ± 123.05 km and 
for a value of HV = 4.0 using Spitzer data only. (c)Information from Tegler et al. (2016).(d)Apmag: object’s average apparent visual magnitude on August 8, 2020, from JPL website https://ssd.jpl.nasa.gov/horizons/app.html#/.
