早安,這裡是太空人林琳(編號BT127),今天我要介紹的是有名的八大行星。
太陽系中,除了最亮的恆星太陽以外,還有八顆大行星,它們本身都不會發光,只能反射太陽光。我們通常把八大行星分成兩類:離太陽最近的水星、金星、地球、火星皆屬於類地行星,外層為岩石、核心是金屬,跟地球居住的環境類似;而後接續排列的木星、土星、天王星和海王星皆屬於類木行星,主要組成為氫與氦,嗯......看類木星球的組成,應該連外星人都無法居住吧?
因為太陽引力的關係,這八大行星會各自以不同的速度,在自己的軌道上圍繞著太陽轉動——八大行星的另一個特點,就是能淨空它們軌道附近的區域。其中體積最大的是木星;而距離太陽最遙遠的海王星表面溫度最低。
Good morning, I’m Lin, an astronaut (No. BT127). Today, I’m going to introduce to you the eight planets.
In our solar system, besides the bright star, the Sun, there are eight planets. They do not emit light but can only reflect sunlight. We normally divide the eight planets into two categories: the terrestrial planets which comprise Mercury, Venus, Earth, and Mars are nearest to the Sun, and have rocky outer layers and metallic cores, similar to the living environment of Earth; these are followed by the Jupiter-like planets, comprising Jupiter, Saturn, Uranus, and Neptune. Their main composition is hydrogen and helium; perhaps even the aliens would not be able to live on them.
Because of the gravitational force of the Sun, the eight planets revolve around the Sun in their own orbits at different speeds. Another characteristic of the eight planets is that they can clear the neighborhood near their orbits. Jupiter is the largest in size while Neptune, which is the furthest from the sun, has the lowest surface temperature.

佇地球人蹛ê太陽系,除了kng-iànn-iànn ê恆星hîng-tshinn 太陽,皮卡貝捌用太空船內底ê偵查tsing-tsa設備siat-pī觀察行星,發現in本身攏袂發光,只是反射日頭光,因為太陽吸引力,這八粒行星會照(tsiàu)家己ê軌道踅太陽--另外一个特別ê所在,這八粒行星會清除家己軌道附近ê物件,太陽系行星運動ê情形,浩大hō-tāi壯麗遮爾仔出眾tsiòng。
皮卡貝落尾有傳信息問teh太空站ê林琳八粒行星ê資訊,伊講地球人共八粒行星分做二類:
較倚太陽ê岩石質(gâm-tsioh) ê行星:水星tshinn、金星、地球、火星,外層是岩石,核心是金屬。紲落來是木星、土星、天王星、海王星主要組成是氫khin佮氦hāi ê巨行星,看起來只有岩石質行星較適合多羅曼斯人kah地球人來活動。
補充觀察重點:第一,這八粒行星當中體積上大ê是木星;第二:離太陽上遠的是海王星,伊表層ê溫度嘛較低。
這就是對八粒行星ê觀察,over。
