第2592期:The Planets Gather for a Show in the Evening Sky

All seven major planets form a kind of parade in the sky at the end of February. Although two of the planets are not visible to the unaided eye, all are on the same side of the sun during the evening hours.2月底，所有七个主要行星构成了天空中的一种游行。 尽管在傍晚时分，两个行星都不可见。This planetary grouping happens when the planets appear to line up in the night sky as seen from Earth. They do not form a straight line, but they do stretch across the evening sky this year.当地球从地球上看到的行星似乎在夜空中排队时，就会发生这种行星分组。 它们没有形成直线，但是今年他们确实遍布整个晚上的天空。The American space agency, NASA, says these astronomical gatherings are common. A parade of four or five planets visible to the unaided eye happens every few years.美国航天局NASA说，这些天文学聚会很普遍。 每隔几年就会发生四到五个行星的游行。A similar parade took place last June, but only two planets could be seen without the use of special equipment. Six planets were visible in January. Four were visible to the unaided eye. In recent weeks, Mercury joined the group.去年6月也举行了类似的游行，但没有使用特殊设备就可以看到两个行星。 一月份可见六个行星。 四个是无助的眼睛可见的。 最近几周，水星加入了该小组。Venus, Mars and Jupiter are all easily visible in the evening. Saturn is now very close to the setting sun and Mercury is close to the horizon, making both hard to see. Uranus and Neptune are the most distant planets. Uranus can be glimpsed with binoculars or a telescope under good conditions. But Neptune is now too close to the sun to be seen.维纳斯，火星和木星在晚上都很容易看到。 土星现在非常接近夕阳，水星靠近地平线，这使得两者都很难看到。 天王星和海王星是最遥远的行星。 天王星可以在良好条件下用双筒望远镜或望远镜瞥见。 但是海王星现在离太阳太近了，无法看到。Seeing the brightest planets is easy. Go outside on a clear night after sunset. The planets will shine brighter than the stars. Mars is a bright, reddish-orange light appearing high in the constellation Gemini. Jupiter is very bright and a little lower than Mars toward the constellation Taurus.看到最亮的行星很容易。 日落后的一个晴朗的夜晚去外面。 行星比星星更亮。 火星是星座的明亮，红橙色的光。 木星非常明亮，比火星驶向金牛座的火星要低一些。Venus, in the constellation of Pisces, is the brightest natural object in the sky besides the sun and moon.金星在双鱼座的星座中，是太阳和月亮以外的天空中最亮的天然物体。There are many stargazing apps available that can help identify the planets and bright stars.有许多观星应用程序可帮助识别行星和明亮的星星。The planets will slowly move lower and lower in the west throughout the spring.整个春季，行星将在西部缓慢移动。
