Astronaut Kimiya Yui captured from ISS the Polaris (North Star). Polaris is a star in the northern circumpolar constellation of Ursa Minor. It is designated α Ursae Minoris (Latinized to Alpha Ursae Minoris) and is commonly called the North Star. With an apparent magnitude that fluctuates around 1.98, it is the brightest star in the constellation and is readily visible to the naked eye at night. The position of the star lies less than 1° away from the north celestial pole, making it the current northern pole star. The stable position of the star in the Northern Sky makes it useful for navigation.
皆さん、おはようございます！
今週も皆さんと共に頑張る為に、少し珍しいタイムラプス映像を紹介いたします。
こちらは、北極星が沈んでいく様子です。ISSでは、赤道を通過するたびに、昇ったり沈んだりするのです。おおぐま座の大きなひしゃくを目印に北極星を探しながらご覧ください。 pic.twitter.com/vpUGZwmh9u— 油井 亀美也 Kimiya.Yui (@Astro_Kimiya) September 28, 2025
