I believe the word you are looking for is "asterism."
A group of stars that form a picture is called a constellation. These patterns are recognized and named by different cultures around the world.
They're called constellations.
It is called a constellation.Constellations.Technically an asterism, but most people usually call it a constellation.
A group of stars that form a picture (at least in human eyes) is known as a constellation.
A group of stars that suggests a pattern is a constellation, but the picture is strictly in the mind of the viewer.
a constellation
When stars combine visually to form shapes or patterns in the sky, it is called a constellation. These groupings of stars often have been given names based on the shape they resemble, such as Orion or Ursa Major.
Constellations are not stars. Groups of stars that look like they form various objects or shapes are called constellations.
It has to do with the stars that cancer are alignded and form the crab picture
Groups of stars have different names depending on the size and nature of the group. A "really big bunch" of stars is a galaxy. A cluster of stars within a galaxy that are "sort of near each other" might be called a local group. There are examples where several stars might form what is called a multi-star system where they all rotate about a common "gravimetric center".
The Solar System is the name of our particular planetary system around our star; Sol. Many stars have been observed to have similar planetary systems and it can be assumed this is a common event in the Universe. Often neighbouring stars will form small groups called clusters, but the Universe is populated by huge groups of stars called galaxies which contain anything from a few million to trillions of stars.
"What is a constellation" - A visible group of stars, all in the same direction, that seem (to us) to form some picture."Are all the stars in the constellation the same distance" - No, they just happen to be in the same direction."Why do groups of stars continue to stay together" - They are extremely far away. They do move, but the distances are enormous, and it takes a while (say, a few thousands of years in the usual case) before we notice a movement."What is a constellation" - A visible group of stars, all in the same direction, that seem (to us) to form some picture."Are all the stars in the constellation the same distance" - No, they just happen to be in the same direction."Why do groups of stars continue to stay together" - They are extremely far away.
