Orange Star in Ursa Minor
Show on Sky Map
A view of the giant orange star
Kochab, from the point of view of two hypothetical bodies in close
orbit. Three thousand years ago, this star marked
Earth's Northern Celestial Pole, but shifts in
the planet's position have seen the Pole move away from
Kochab and towards Polaris.
The second brightest star in
Ursa Minor is an orange
giant lying just over one hundred light years from
Earth's Solar System.
Like all the stars of Ursa Minor, orange Kochab lies close to the Northern Celestial Pole.
The Galactic position and direction of Kochab relative to Earth's Sun. Note that, at this
extreme scale, the two stars are effectively in the same place.
The giant orange star
Kochab is one of the two Guardians of the Pole.
The other, far more distant Guardian
star Pherkad is just visible in the background of this image.
