摘要
The Apollo asteroid 1983 TB has an orbit very similar to the Geminid meteor stream and it is most likely that the two are related. If this is so then 1983 TB could be the degassed nucleus of the responsible comet, thus establishing a probable evolutionary connection between the two groups of objects. Since its orbit nearly intersects the Earth's orbit, close encounters may be expected which will provide good observing conditions for this interesting object. In this communication, we present orbital calculations determining the future orbital behaviour of 1983 TB, highlighting good observing times. © Royal Astronomical Society • Provided by the NASA Astrophysics Data System.
