the best example would be a GLOBULAR CLUSTER ( very high relative density )

Constellations are a group of stars that APPEAR to be close to one another, because they are in almost the same position in the sky WHEN VIEWED FROM EARTH. They can in fact be very very far away from each other, and if you view the constellation from the side you can see the stars really have almost no spatial relationship.
A tight cluster of stars that remains tightly clustered when viewed from any direction (that is, stars that really are close together) is called a globular cluster. The Pleiades are a good example, there are hundreds of stars all packed together in a few light years. They are close together because they have just been formed very recently (in star lifetimes, that is): about 10,000 years ago, which makes them some of the newest stars visible from Earth. Being so young, they have not yet spread apart. They will eventually scatter, being pushed out into the void by the interactions of their solar wind. In another million years or so the Pleides will be scattering.

Cluster is the right term for a group of stars grouped close together. galaxies have more stars and some are far apart, a galaxy can have many clusters in the star formations within. Constellation is a shape made in the sky by a group of starts who often enough are not close but appear close to us by the way they are placed in the night sky.

Sorry to see incorrect answers on this !
They are called " Star Clusters "
Many of the stars in the universe are part of multiple star systems. Most appear to be part of a binary system where two stars orbit a common center of gravity. A few are even part of a triple star system. But some stars are also part of a larger group. They can be found together in associations known as star clusters. Star clusters are groupings of stars held together by a common gravitational bond. They vary greatly in size and shape as well as the number of stars. They also vary in age from just thousands of years to billions of years old. Gravity is the force that binds these cosmic swarms together. Star clusters are among the most spectacular objects in the sky. Many of these clusters can be seen with the naked eye on a dark night. Astronomers have divided star clusters into two main types according to their shape and number of stars. The can all be classified as either open clusters or globular clusters.

If by "the" huge group of stars you mean the band of starlight across the night sky, it's the Milky Way. You're looking at the galaxy we're in from about 60% of the way out from the center.
If you're looking for the generic name for a dense cluster of stars, perhaps you want "globular cluster". This is a dense, roughly spherical cluster of gravitationally bound stars, typically containing hundreds of thousands up to a few million stars.

a huge group of stars would be a cluster a constelation would be an arrangement of stars like The Big Dipper or Orion. And the Milky way is a galaxy in fact our galaxy although it may appear to be a cluster of stars in the midnight sky it is the arm of the Milky Way that you see.

That is a globular cluster; they are usualy in the halo of the galaxy and are made up of older, dimmer, metal-poor stars.

In the constellations, an example is the Pleides, or seven sisters... However they only appear close from our line of vision. They are actually very far apart from each other.

They are then called a CLUSTER.. usually though, it is called a STAR CLUSTER followed by a name
