a physical grouping of stars in called a cluster. however if u mean a cluster you can see with your eyes you probably mean a constellation
hope this helps :)
A grouping of stars with a loose and disorganized appearance, containing no more than a few thousand stars, is called an open cluster. These clusters are typically young and are held together by gravitational forces. They are spread out across the sky and are great objects for amateur astronomers to observe.
An asterism, which is a grouping of stars that form a recognizable shape.
A star pattern is a design or arrangement of stars in the sky that forms a recognizable shape or image. These patterns are created by connecting the brightest stars in a constellation with imaginary lines. Star patterns have been used throughout history for navigation, storytelling, and cultural symbolism.
A grouping of eggs in a nest is called a clutch.
A solar system is a star with planets orbiting it. A constellation is our view of several stars in patterns. Most constellations are just different stars that are very far apart, but from our point of view they seem close.
A loose grouping of a few thousand stars is called a cluster. The stars in a cluster have similar characteristics, which means that they have a common origin.
I think you are referring to a cluster of stars.

A misty group of stars is referred to as a star cluster. Star clusters are groups of stars that are gravitationally bound together and can be classified as either open clusters (loose grouping of stars) or globular clusters (more densely packed grouping of stars).
Grouping of stars in constellations is completely arbitrary as it depends solely on our point of view (stars in particular constellation aren't really near together and can be separated by great distances - in fact stars belonging to two different constellations may be closer together than stars in just one of them) and was influenced by our mythological views. Grouping of planets in a solar system at least has an actual basis: planets are gravitationally bound to a star and are located nearby.
An apparent grouping of stars (as the Big Dipper) is an asterism, formerly called a constellation. (A constellation is now a bordered area of sky, equivalent to a state on a political map). Stars which are actaully associated, may be a cluster, a nebula or a galaxy.
Grouping stars by brightness
A constellation is a grouping of stars that people say looks like a person or a an object.
They are a less formally defined grouping of stars.
Depending on size, that's probably either a globular star cluster (a vaguely spherical grouping of tens of thousands of stars within a galaxy), or a galaxy (an elliptical, disc-shaped or irregular grouping of billions of stars - including several globular clusters).
We use the word "asterism" for a grouping of stars that isn't one of the 88 "official" constellations recognized by the International Astronomical Union, the IAU. The most famous asterism is the central part of Ursa Major; we call it the "big dipper".
