環のある惑星、土星
Saturn, the planet with a ring

繊細で愛らしい表情をたたえ
楽しげに環を傾ける土星

カッシーニの空隙（くうげき）が
きりりと黒いラインを描く

望遠鏡を覗き込む子どもたちが
一番目を輝かせる惑星です

Saturn's ring looks like a disk with stripes on it.
The ring is several hundred thousand kilometers long, but is only one hundred meters thick.

Through telescope, children would be most excited to find the straw-hat planet.
