VENUS-INTERCEPTING METEOROID STREAMS

This study is motivated by the possibility of determining the large-bo dy meteoroid flux at the orbit of Venus. Towards this end, we attempt to estimate the times at which enhanced meteoric activity might be obs erved in the planet's atmosphere. While a number of meteoroid streams are identified as satisfying common Earth and Venus intercept conditio ns, it is not clear from the Earth-observed data if these streams cont ain large-body meteoroids. A subset of the Taurid Complex objects may produce fireball-rich meteor showers on Venus. A total of 11 short-per iod, periodic comets and 46 near-Earth asteroids approach the orbit of Venus to within 0.1 au, and these objects may have associated meteoro id streams. Comets 27P/Crommelin and 7P/Pons-Winnecke are identified a s candidate parents to possible periodic meteor showers at the orbit o f Venus.
