The asteroid-comet continuum
The practical distinctions between asteroids and comets, viewed as products of accretion on

The dynamical origins of the dark comets and a proposed evolutionary track
So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that
exhibit nongravitational accelerations inconsistent with radiative effects. These objects …
