Полярная звезда Polaris: The North Star

Двойная звезда φ Персея Phi Persei: Double Star
2.10.1999

It's clear who is the biggest star in this binary system. Based on recent results, this artist's vision of the double star Phi Persei, 720 light years away, shows a bright, rapidly rotating massive star surrounded by a disk of gas. A small companion star orbits 100 million miles away.
