It was Sir William Herschel who first recognized that it was not a star in 1781, making Uranus the first planet to be discovered with a telescope.

直到威廉赫歇尔爵士在1781年，才发现它不是一颗恒星，天王星因此成为第一颗被望远镜发现的行星。

Only a few decades later, the astronomer Sir William Herschel confirmed this idea by painstakingly cataloging the positions and distances of vast numbers of stars.

仅在几十年后，天文学家威廉·赫歇尔爵士通过煞费苦心地对大量恒星的位置和距离进行编目，证实了这一想法。
