逐月之旅

英文原文:Explanation: How big is planet Earth's Moon ? Compared to other moons of the Solar System, it's number 5 on the largest to smallest ranked list , following Jupiter's moon Ganymede , Saturn's moon Titan , and Jovian moons Callisto and Io . Continuing the list, the Moon comes before Jupiter's Europa and Neptune's Triton . It's also larger than dwarf planets Pluto and Eris. With a diameter of 3,475 kilometers the Moon is about 1/4 the size of Earth though, and that does make it the largest moon when compared to the size of its parent Solar System planet. Of course in this serene, twilight sea and skyscape, August's rising Full Moon still appears small enough to be caught in the nets of an ancient fishing rig. The telephoto snapshot was taken along the Italian Costa dei Trabocchi , on the Adriatic Sea. 说明: 地球的月球有多大[2]? 若将太阳系的卫星依大小排序[3],月球排名第五,仅次于木星的盖尼米德(Ganymede)[4]、土星的泰坦(Titan)[5]、以及木星的卡利斯托(Callisto)[6]与木卫一(Io)[7]。继续往下,月球则大于木星的欧罗巴(Europa)[8]与海王星的崔顿(Triton)[9]。它的体积甚至超越了矮行星[10]冥王星(Pluto)与阋神星(Eris)。 月球的直径约为 3,475 公里,相当于地球的四分之一。也正因如此,若将卫星与其母行星相比,月球是太阳系中相对比例最大的卫星。 然而,在这幅宁静的暮色海天景致中,八月升起的满月看起来仍是那么小,仿佛能被古老的渔网捕捉。这张长焦距摄影作品取景于意大利亚得里亚海沿岸的「Trabocchi 海岸[11]」。
