We have obtained polarimetric measurements of asteroid (101955) Bennu, a presumably primitive near-Earth object (NEO) that is the target of NASA's sample return mission OSIRIS-REx. During our observing campaign, Bennu was visible from Earth under a wide range of illumination conditions, with phase-angle in the range 16 to 57 degrees. Together with (3200) Phaethon and (152679) 1998 KU2, observed very recently, Bennu is the only existing example of a primitive NEO observed in polarimetric mode… Expand

Unusual polarimetric properties for interstellar comet 2I/Borisov
TLDR
Polarimetric observations of comet 2I/Borisov are performed using the European Southern Observatory Very Large Telescope to derive the physical characteristics of its coma dust particles, and it is shown that the polarization of 2I / Borisov is higher than what is typically measured for Solar System comets.
