What characteristic do stars in a constellation or asterism share?

There is normally no similarity between stars in a constellation or asterism other than the direction they are in relation to Earth. 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.

Answer
More specifically, all of the stars cluster orbit around some common point of gravity.

What is the difference between asterism and constellations?

A constellation. (Also an asterism does this.)
What is a smaller group of stars within a constellation.?
It can be called a star cluster, an open cluster or an asterism.

A group of stars such as the big dipper?
A grouping of stars, that isn't a constellation, is called an asterism.
What is small group of stars that forms a pattern within a constellation?
An asterism.
What is a small group of stars that forms a pattern within a constellation?
An asterism.
What is a small group of stars that form a pattern within a constellation?
An asterism.
What is an imagined group of stars?
That would be a constellation. There are 88 recognized constellations. A subset of a constellation or other set of stars is called an asterism.
What are a group of stars that form an image?
The group is known as a constellation.
How is it possible to change asterism in a constellation?
You can pick any group of stars that seem to form a certain shape. That would be an asterism.
A group of stars that forms an imaginary picture is called what?
A constellation. (Also an asterism does this.)
Group of stars that forms a picture is?
That is called an ASTERISM. (For a somewhat related concept, see also: CONSTELLATION)
What is a gruop of stars called?
The proper term for a group of stars is "asterism". They can also be known as a "cluster" and/or a "constellation".
