<p>　寒い中，月と木星を直線で結んだ真ん中のちょっと右あたり，望遠鏡を使っているわけではないので，そのあたりをぐぐっと寄って，探して，捉えることができました。これでやっと，地球を除くすべての太陽系の惑星を手元に置くことができました。</p>



<p>　あふれ出そうな嬉しさで，気持ちがいっぱいです。年明け，この喜びを学生さんに話しても，何も伝わらないだろうな・・・と思いますが，今はそれは置いておいて！</p>

<p>　地球（Earth）が属する太陽系（Solar System）には，8つの惑星があります。恒星の太陽（sun）に近い順に，水星（Mercury），金星（Venus），地球（Earth），火星（Mars），木星（Jupiter），土星（Saturn），天王星（Uranus），海王星（Neptune）と並んでいます。</p>



<p>　この年末まで，地球を除く7つの星を一度に見ることができます。</p>
