香港月出时间: 5月5日 6:04 pm (GMT +8) 香港月没时间: 5月6日 5:32 am (GMT +8) 月亮近地点: 5月6日 12:34 pm (GMT +8) 相等于 5月5日 11:34pm (EST) "超级月亮" 是满月 (或新月) 与近点月同时发生的近点朔望月。这是描述月球在椭圆轨道上绕着地球公转，行经近地点之时，同时又在日地联线上的专有名词。 此种结合的超级月亮被认为会引发海洋、地壳和潮汐的变化，例如地震、火山爆发和海啸发生风险的增加。但是，这种关联性一般是难以令人信服的。 超级月亮说法始见于1979年，为占星家理查德·诺勒所定义。经多年修正后，该天象指的是：新月或满月时期，月球与地球间距离较平常为近，换言之，也就是地球与月球间距离低于或接近35.4万公里 (220,000英里)。 http://zh.wikipedia.org/wiki/超级月亮 A "supermoon" is the coincidence of a full moon (or a new moon) with the closest approach the Moon makes to the Earth on its elliptical orbit, or perigee, leading to the technical name for a supermoon of the perigee-syzygy of the Earth-Moon-Sun system. The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions. However, the evidence of such a link is widely held to be unconvincing. The Moon's distance varies each month between approximately 357,000 kilometers (222,000 mi) and 406,000 km (252,000 mi) due to its elliptical orbit around the Earth (distances given are center-to-center). The Moon will be at its closest point in orbit to the earth and the Sun, Earth and Moon will be aligned. The moon will appear about 16% larger and 30% brighter. http://en.wikipedia.org/wiki/Supermoon
