What are pointer stars?
Pointer stars are stars which are used to find an area of the sky. For example, you might be looking for a dim galaxy or small star. You can use two bright stars on a map, find those in the sky, and then find the approximate position of what you are trying to look at by using the location and spacing of the more obvious pointer stars.
What characteristic do stars in a constellation or asterism share?

They are normally a collection of dimmer near by stars and brighter further away stars.An example of this is the constellation Centaurus. AlphaCentauri is the closest star system to earth. It has 3 stars, Proxima Centauri which is about 4.2 light years and Alpha Centauri A and B that are 4.3 light years away.On the other side Beta Centauri or Hadar is a bright star 350 light years away.There are however examples where some or most of the stars are connected.Take the asterism the big dipper or plough in the constellation Ursa Major. Merek (Beta Ursae Majoris), Phecda (Gamma Ursae Majoris), Megrez (Delta Ursae Majoris), Alioth (Epsilon Ursae Majoris) and Mizar (Zeta Ursae Majoris) all seem to be about the same distance from Earth (between 78 and 84 light years) and all seem to be moving in the same direction. They are known as the Ursa Major Moving Group.Only Dubhe (Alpha Ursae Majoris) and Alkaid (Eta Ursae Majoris) do not seem to be connected.
