Uranus was the first Planet to be discovered in modern times.
天王星是在現(xiàn)代第一顆被發(fā)現(xiàn)的行星。
Although it is just possible to see Uranus with the naked eye under ideal circumstances, it was the musician and mathematician Sir William Herschel who formally identified Uranus In March 1781.
在最理想的情況下可以用肉眼看到天王星,在1781年3月音樂家,數(shù)學(xué)家威廉•赫歇爾爵士正式確認(rèn)天王星。
Uranus is a giant gas planet. It is 51200km in diameter, but is made of 83% hydrogen and 15% helium.
天王星是一顆巨大的氣體行星。直徑51200公里,但是卻由83%的氫和15%的氦組成。
The strange thing about Uranus is that it is tilted over on one side to 98º. This means that Uranus rolls around the Sun on its side.
奇怪的是, 天王星的自轉(zhuǎn)軸可以說是躺在軌道平面上的，傾斜的角度高達(dá)98°。這意味著天王星將面對(duì)太陽。
For one half of a Uranus' year, about 42 years, the ‘North' of Uranus is facing the sun and is in constant sunlight while the ‘South' is in darkness.
天王星在前42年，在至日前后時(shí)，北部一個(gè)極點(diǎn)會(huì)持續(xù)的指向太陽，南部另一個(gè)極點(diǎn)則背向太陽。
Then for next 42 years the situation is reversed and the "Southern" hemisphere gets all the light.
然后另一個(gè)42年情況逆轉(zhuǎn),南半球會(huì)指向太陽。
Uranus has a faint ring system, also discovered by Herschel.
天王星有微弱的環(huán)系統(tǒng),也是被赫歇爾發(fā)現(xiàn)。
It has over 27 satellites, most of them not much bigger than large rocks, but 5 of them have been given names taken from Shakespeare.
它有超過27個(gè)衛(wèi)星,但它們大多數(shù)都不比巖石大,但5顆已經(jīng)被命名，這些命名全部取自莎士比亞。
Uranus has only ever been visited once by a space craft, NASA's Voyager 2 flew past in 1986. There are currently no plans to visit Uranus in the near future.
天王星只有一個(gè)人類訪客,美國宇航局的航行者2號(hào)在1986年曾經(jīng)抵達(dá)。目前在不久的將來還沒有計(jì)劃去參觀天王星。
