On Confirmed and Suspected Binary Asteroids Observed at the Center for Solar System Studies
Abstract
The analysis of observations made at the Center for Solar System Studies from 2020 September to 2021 January led to the discovery that the Vestoid asteroid 3865 Lindbloom is a fully synchronous binary. The orbital period is 26.016 h and the ratio of the effective diameters is 0.65 < Ds/Dp < 1.0. Assuming a bulk density of 2 g/cm, Dp <= 7.2 km, Ds >= 4.6 km, and the center-to-center separation is 20 km. Other objects presented here were found to have secondary periods: 4503 Cleobulus, (22056) 2000 AU31, 25465 Rajagopalan, (46818) 1998 MZ24, (48205) 2012 TQ78, 2013 PY6, and 2020 PD1. Of those, only 1998 MZ24 and 2013 PY6 might be said to show mutual events due to a satellite.
