And scientists keep finding more water wherever they look. On September 28, researchers reported that Dione - a small moon of Saturn - probably has a subsurface ocean, too.
而且,科学家还在不断发现水资源丰富的星球。9月28日,研究人员报告称,土星的一颗小卫星土卫四很可能也拥有一片次表层海洋。
To see just how Earth stacks up agains other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA’s Jet Propulsion Laboratory who’s crunched the numbers on just how much water might be out there.
为了弄清地球在太阳系海洋世界的实力,商业内幕网联系了美国宇航局喷气推进实验室的行星科学家史蒂夫•凡思,他运算出了其他星球的水量数据。
The to-scale graphic below uses Vance’s data to show the plausible volumes of water (both liquid and ice) for the nine ocean worlds verified so far:
下面的这张等比例绘制图运用凡思的数据显示出到目前为止已证实的太阳系九大行星海洋的理论水量(包括液态和固态水):
In order of how much water they have, from the least to the most, they are: Enceladus, Dione, Earth, Europa, Pluto, Triton, Callisto, Titan, and Ganymede.
按照拥有的水量排序,从少到多依次是:土卫二,土卫四,地球,木卫二,冥王星,海卫一,木卫四,土卫六和木卫三。
