Smaller objects regularly inhabit the Earth's orbit, usually leaving after a few months to continue on their celestial(天上的) journeys. The discovery is considered a major breakthrough for space research because scientists had been working toward visiting asteroids(小行星) outside of Earth's orbit for research. While these temporary moons are too small for a shuttle landing, they are prime for research from a relatively close distance. However, it's still to be determined whether the 1 / 3 精品文档 announcement will capture the public's attention like previously revealed New Moons. Either way, it should be a decidedly more pleasant experience for all involved. The new paper titled The population of natural Earth satellites, from Cornell University's Mikael Granvik, Jeremie Vaubaillon and Robert Jedicke states that these secret moons enter and exit the Earth's orbit without notice. At any given time, there should be at least one natural Earth satellite of 1-meter diameter orbiting the Earth, Granvik writes. Scientists have confirmed at least one such temporary moon, discovered by the Catalina Sky Survey in Arizona in 2006. Our results are consistent with the single known natural 2006 RH120, a few-meter diameter object that was captured for about a year starting in June 2006, the report says. 上一篇英语: 癌症疫苗研究获重大突破下一篇英语: 每 个恒星都有行星围绕查看更多关于科技Science的文章网友 同时还浏览了: 2 / 3 精品文档 什么是雅思机经,如何巧用雅思机 雅思写作评分任务完成情况 雅思写作评分标准:连贯与衔接 雅思写作评分标准:词汇资源 雅思写作评分标准:语法的多样性 雅思考试合格标准 3 / 3
