Astrometric recovery and follow-up of near-Earth asteroids
Abstract
We discuss the astrometric observation of minor solar system bodies from Victoria with particular reference to 40 recently monitored near-Earth asteroids. The future encounter circumstances over the next 50 years have been calculated for some interesting individuals of this group. 1991 JW, whose orbit is the most similar to Earth's of any sizeable (>0.5 km) asteroid yet discovered, shows appreciable orbital evolution within this time interval.
