    ㄜ,去天王星旅遊要帶什麼東西? 太空裝備。

    可以作什麼活動?不太清楚,還沒有人上去過。

    你們老師出的題目很好笑。

    Uranus is the seventh planet from the Sun and is the third largest in the solar system. It was discovered by William Herschel in 1781. It has an equatorial diameter of 51,800 kilometers (32,190 miles) and orbits the Sun once every 84.01 Earth years. It has a mean distance from the Sun of 2.87 billion kilometers (1.78 billion miles). It rotates about its axis once every 17 hours 14 minutes. Uranus has at least 22 moons. The two largest moons, Titania and Oberon, were discovered by William Herschel in 1787.

    The atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons. Methane in the upper atmosphere absorbs red light, giving Uranus its blue-green color. The atmosphere is arranged into clouds running at constant latitudes, similar to the orientation of the more vivid latitudinal bands seen on Jupiter and Saturn. Winds at mid-latitudes on Uranus blow in the direction of the planet's rotation. These winds blow at velocities of 40 to 160 meters per second (90 to 360 miles per hour). Radio science experiments found winds of about 100 meters per second blowing in the opposite direction at the equator.

    天王星是從太陽數來第七顆、倒數第三顆行星,也是太陽系第三大行星,軌道半徑為287,099萬公里 (19.218AU);赤道處直徑為51,118公里;質量是8.683x1025公斤。與海王星比起來,天王星體積較大但質量較小。 英國天文學家 William Herschel 在用他的望遠鏡有系統地搜尋之後,在1781年3月13日發現了天王星。

    天王星最特別的地方是天王星的自轉軸傾斜度為98度,幾乎橫躺在公轉軌道面上,如果我們在天王星,就會發現天王星會持續半個天王星年(42地球年)面對太陽,然後半個天王星年是黑夜(天王星繞著太陽照一圈需要84.01個地球年)。

    天王星與其他類木行星一樣主要由氫和氦組成,但天王星的大氣和內部都富含甲烷。天王星的最外層是由氫、氦和甲烷組成的大氣;大氣下面是由冰、甲烷和氨組成的內層;中心是由岩石組成的核。 已發現的天王星的衛星共有21個。
