五星聯(lián)珠or五星連珠?

On June 15, innermost planet Mercury had wandered about as far from the Sun as it ever gets in planet Earth’s sky. Near the eastern horizon just before sunrise it stands over distant Andes mountain peaks in this predawn snapshot from the valley of Rio Hurtado in Chile. June’s other morning planets are arrayed above it, as all the naked-eye planets of the Solar System stretch in a line along the ecliptic in the single wide-field view. Tilted toward the north, the Solar System’s ecliptic plane arcs steeply through southern hemisphere skies. Northern hemisphere early morning risers will see the lineup of planets along the ecliptic at a shallower angle tilting toward the south. From both hemispheres June’s beautiful morning planetary display finds the visible planets in order of their increasing distance from the Sun.
在6月15日那天,太陽系最內(nèi)圍的行星─水星,在地球天空游蕩到離太陽最大張角的位置。在這幅攝于智利里奧烏爾塔多山谷的黎明前影像里,水星出現(xiàn)在日出前的東方地平線附近,低懸在遠方的安第斯山峰上方。而其他6月可見的清晨行星,則出現(xiàn)在它的上方。在這片單曝光視野里,這些肉眼可見的太陽系行星,沿黃道面排列有如聯(lián)珠。影像里,向北傾側(cè)的太陽系黃道平面,陡峭地穿過南半球的天空。相較之下,北半球早起的人們,所見的行星排列則是以較小的角度向南傾斜。此外,從南北半球看出去,在6月之時,這些美麗清晨行星的排列順序,忠實的反應它們與太陽漸增的距離。
