An observational investigation of the comet-asteroid connectionRecent observations indicate that comet nuclei and certain asteroids, particularly near-Earth asteroids (NEA) and the distant asteroids, may have much in common. The authors investigated the possible connection between comets and asteroids via two methods. A spectroscopic survey of two groups of asteroids that may be related to comets, namely the NESs and Trojan asteroids, indicates that we cannot dispel the hypothesis of a main-belt origin NEAs, while the Trojan survey shows that the Trojans and the known comet nuclei are spectrally similar over the wavelengths examined. Results of attempts to determine the mass loss rates of NEAs indicate that we cannot exclude the possibility that low-activity comets exist in the NEA population and have escaped detection simply because their small sizes result in mass loss rates which are below the detection limit.
