摘要：根据火星和金星相对于地球的接近行星彗星轨道的数量，应该有充足的机会观测这两颗行星的流星活动。火星、地球和金星上接近行星的木星族彗星 (JFC) 的比例为 4:2:1，这表明与 JFC 相关的爆发在火星上比在地球上更频繁。接近行星的哈雷型彗星（HTC）的相对数量意味着这三颗行星的年度流星活动水平相似。我们确定了几个可能发生近彗星爆发的实例（Jenniskens, P.: 1995, Astron. Astrophys. 295, 206–235）。 2006 年夏天，欧空局金星快车航天器可能会在金星观测到与 45P/Honda-Mrkos-Padjusakova 相关的这种类型的双爆发。同样，日本 Planet-C 金星轨道飞行器可能会在 2011 年 7 月观测到与 27P/Crommelin 近日点经过有关的一次爆发。还有几个额外的机会可以从火星上观测到此类爆发。 2019 年至 2026 年与彗星 38P/Stephan-Oterma、13P/Olbers 和 114P/Wiseman-Skiff 相关。
Abstract.Based on the number of planet-approaching cometary orbits at Mars and Venus relative to the Earth, there should be ample opportunities for observing meteor activity at those two planets. The ratio of planet-approaching Jupiter family comets (JFCs) at Mars, Earth, and Venus is 4:2:1 indicating that JFC-related outbursts would be more frequent at Mars than the Earth. The relative numbers of planet-approaching Halley-type comets (HTCs) implies that the respective levels of annual meteor activity at those three planets are similar. We identify several instances where near-comet outbursts (Jenniskens, P.: 1995, Astron. Astrophys. 295, 206–235) may occur. A possible double outburst of this type at Venus related to 45P/Honda-Mrkos-Padjusakova may be observable by the ESA Venus Express spacecraft in the summer of 2006. Similarly, the Japanese Planet-C Venus orbiter may observe an outburst related to 27P/Crommelin’s perihelion passage in July 2011. Several additional opportunities exist to observe such outbursts at Mars from 2019 to 2026 associated with comets 38P/Stephan-Oterma, 13P/Olbers and 114P/Wiseman-Skiff.
