摘要：
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.
