Context. The classification of the minor bodies of the Solar System based on observables
has been continuously developed and iterated over the past 40 yr. While prior iterations …

Context. The sample of Solar system objects has dramatically increased over the last
decade. The number of measured properties (eg, diameter, taxonomy, rotation period …

Context. The Gaia mission of the European Space Agency (ESA) has been routinely
observing Solar System objects (SSOs) since the beginning of its operations in August 2014 …

Context. The populations of small bodies of the Solar System (asteroids, comets, Kuiper-Belt
objects) are used to constrain the origin and evolution of the Solar System. Both their orbital …

We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects
(NEOs) collected on the NASA InfraRed Telescope Facility as part of the MIT-Hawaii NEO …

Evidence is seen for young, fresh surfaces among Near-Earth and Main-Belt asteroids even
though space-weathering timescales are shorter than the age of the surfaces. A number of …

We successfully observed 191 near-Earth asteroids using the Arecibo Observatory's S-band
planetary radar system from 2017 December through 2019 December. We present radar …

Belt objects) are used to constrain the origin and evolution of the Solar System. Their orbital …

The identification of meteorite parent bodies provides the context for understanding
planetesimal formation and evolution as well as the key Solar System events they have …

Context. The study of planet-crossing asteroids is of both practical and fundamental
importance. As they are closer than asteroids in the Main Belt, we have access to a smaller …
