Answer 2

The Dipper is something else to astronomers: It's a star cluster seen closeup. With the exception of Dubhe and Alkaid -- the first star in the cup and the last star in the handle -- the inner five stars of the Dipper share the same motion through space. Astronomers call this the Ursa Major cluster. In all, the cluster includes about 17 bona fide members. It may be larger still. Another 100 stars (including Sirius) are known to be moving in approximately the same direction in space as the Ursa Major cluster.

Moreover, these stars all have about the same ages, implying they were all born out of the same stellar chrysalis. This larger group of stars is known collectively as the Ursa Major stream.

At any rate, the five inner Dipper stars comprise the heart of the nearest star cluster to Earth, the center of which lies about 80 light-years away.
