14-21 Leonids per hour, at about dozens.

<P> Had many wonderful performance history of the Leonid meteor shower again. .Astronomical Society of Jiangsu Province to experts, the more favorable meteor shower observation time is 14 to 21 November, particularly after 23:00 in the evening of the 17th, the Leonid meteor shower will likely have an "outbreak." .By then, dozens of meteors per hour across the sky about. .</ P> <P> It is understood that the Leonid meteor shower of the parent comet is "Temple - Tuttle" (Tempel-Tuttle) comets. .When the comet flew perihelion, due to too much sunlight, so Comet parent material on the ice sublimation, projection countless comet dust or debris. .Orbit intersects the Earth and the comet, these particles and the Earth's atmosphere, friction, combustion, formation of a meteor shower. .Historically, there will be about once every 33.5 years, the Leonid meteor storm, the Leonid meteor shower in 2001 there have been more than 3,000 meteors per hour spectacle. .</ P> <P> Astronomical Society of Jiangsu Province, relevant experts, recent observations indicate that the Leonid meteor shower burst of fire when the common particularly bright meteor, the meteor in the night sky trailing a long trail, very nice. .</ P> <P> astronomers say, 14 -21 days, 40 minutes after sunset, amateur astronomers can observe. .Place the best choice in open lots, patiently wait for a meteor. .Note that the heyday of the 17 observations of the Leonid meteor shower, I happened to be the last day of full moon, the bright moonlight on observation of meteor shower bad. .</ P> <P> Purple Mountain Observatory, Chinese Academy of Sciences researcher, Wang thought to remind the majority of amateur astronomers, as human beings can not accurately calculate the current meteor shower parent comet dust particles in the distribution structure, which can not be like forecasting solar and lunar eclipses that of the meteor shower .make an accurate prediction of the occurrence and size. .Observed when the public should be psychologically prepared for this. .(End) </ P> <P align=center> Recommended articles: </ P> <P align=center> using technology to track the virus "suspects" </ P> <P align=center> 11 项 the most significant invention of the year .was "Time" report </ P> <P align=center> tip down: the ancient Egyptians will be flying technique </ P> <P align=center> medical miracle, HIV infection died of self-healing </ P> </ .p>.
