The name "Dubhe" comes from the arabic for "bear" and is one of the two "pointer stars" we use to locate Polaris, the North Star. There's a lot going on in its neighbourhood: it is orbited by another star Dubhe B as well as a close pair of two other stars, named Dubhe C. Dubhe is about 124 light years from us, so light you're seeing left the star in about 1884.
And here's one last cool fact: because the earth actually "wobbles" very slowly (this is called "Precession") Polaris hasn't always been the star closest to the northern celestial pole. In fact, about 5100 BC, Dubhe was the "North Star," and will be again in 20,500 AD. If someone is reading this at that time, would you please hike out to Blackfoot and change the cache names for me? Thanks much. :-)
